LibreOffice Shortcut Keys Made Easy

Saturday 21st of November 2020 02:46:00 PM

Here's a colorful poster to learn LibreOffice quicker and easier for everyone. This is a table of selected shortcut keys of four office suite programs namely Writer, Calc, Impress, and Draw. Actually I made this for my computer course in Indonesia but I believe it's also good to share here. You can share this table, print it, place it on your favorite places, and practice a lot. Happy learning!


Download: PNG (2800x2900)Edit: SVG (1 MB)
Description: I made this with Inkscape after being inspired by somebody shared similar table for Microsoft Office. I wish this helps everyone in general and my students in particular.

How To Install Trisquel 9.0 Etiona

Wednesday 11th of November 2020 05:57:00 PM

This tutorial explains step by step to have your computer with Trisquel 9.0. Don’t worry this is intended for beginners so everyone can try. You will prepare at least two disk partitions and going through about twenty minutes to finish it. For your information, different to Ubuntu, Trisquel supports 32 bit as well as 64 bit computers and I encourage fellow Lenovo ThinkPad owners to try it happily. You can practice this guide either normally, in dualboot mode, bios legacy and uefi, or into external storage device. Last but not least, you can also do this inside a virtual machine like AQEMU. Now let’s go! (Trisquel 9 computer on its installation process)Subscribe to UbuntuBuzz Telegram Channel to get article updates.

Summary 
  • Set Language
  • Set Keyboard
  • Set Network
  • Set Partitioning Mode
  • Create Partitions and Start Installing
  • Set Timezone
  • Set User Login
  • Wait
  • Finish

 

Preparations
  1. Download Trisquel. Choose 32 bit edition if your computer is sold before 2011, or choose 64 bit instead if your computer either has 4GB RAM or comes with Windows 10.
  2. Create Trisquel bootable USB flash drive, a medium to install the OS into your computer, by writing the ISO file into it. For this purpose, you can use Unetbootin program on Windows and Mac, or GNOME Disk Utility which is preinstalled built-in on most GNU/Linux.
  3. Create 3 hard disk partitions by size and filesystem respectively, 500MB FAT32 and 1GB linux-swap and >=20GB EXT4 which will be EFI, SWAP, and ROOT partitions respectively. For this purpose you can use GParted Partition Editor program which is preinstalled built-in on Trisquel itself and almost all other GNU/Linux distros.
  4. If you plan a dualboot, backup your important data from Windows partitions to external storage correctly.
  5. If you plan USB flash drive instead of hard disk drive installation, I recommend you to use EXT2 instead of EXT4 filesystem.
  6. For complete beginners, ask person with computer knowledge near you to guide you while practicing this tutorial and doing mentioned backup.

 (Computing showing its hard disk with total capacity of 22GB with 3 partitions already prepared: first is EFI 500MB fat32, and second is SWAP 1000MB linux-swap, and third is ROOT 20GB ext4)


Booting

Plug your bootable USB in and boot your computer up into USB.

When your computer boots up, you should eventually see Trisquel 9.0 screen giving you options either to TRY or to INSTALL. Use arrow key up and down to select and press Enter to go. Select 'Try Trisquel without installing'. Continued below.

  (Trisquel initial boot screen before the installation) Now you landed into its beautiful desktop, either you access GParted here, or you immediately go to the installation process if you are ready. If you already have the required partitions, find on desktop an item Install Trisquel, double click it and the installation starts.(Advantage of choosing TRY instead of INSTALL is that you can run other programs before doing the actual installation, like browsing your files and partitioning)

Step 1

Select English and Continue.


Step 2

Select English (US) keyboard layout and Continue.


Step 3

Unselect Download updates option and Continue.


Step 4

Select Something Else option and Continue.


Step 5
 
  • 1) Create EFI System Partition
  • 2) Create SWAP partition
  • 3) Create ROOT partition 
  • 4) Set bootloader location
  • 5) Start the installation 

 

1) Creating EFI Partition:

Skip this step if your computer is BIOS Legacy not UEFI.

  • Select the smallest size partition you prepared.
  • Click Change.
  • Do not change Size:.
  • Set Use As: FAT32 file system.
  • Enable Format the partition if allowed.
  • Set Mount point: /boot/efi
  • OK



2) Creating SWAP partition:

  • Select the middle sized partition prepared.
  • Click Change.
  • Do not change Size.
  • Select use as: swap area.
  • Enable format file system if possible.
  • OK.


3) Creating ROOT partition:

  • Select the largest partition prepared.
  • Click Change.
  • Do not change Size.
  • Set Use as: EXT4 Journaling Filesystem.
    (For USB Flash Drive installation, select EXT2 Filesystem instead.)
  • Enable Format the partition option if possible.
  • Set Mount point: /
  • OK.
 

4) Set bootloader location:


  • Below the bootloader option, select /dev/sda hard disk drive if your ROOT partition is under /dev/sda too.
  • For USB Flash Drive installation, do not set bootloader location into hard disk drive but into the USB flash drive. So if your ROOT partition is under /dev/sdb flash disk drive, then set bootloader into /dev/sdb too. 


5) Start the installation:

  • Click Install Now
  • Check carefully everything appeared then on screen.
  • If everything in that summary is OK, no mistake found, then click Continue.
 
Step 7

Select your timezone by clicking one point on the map or typing your city name.


Step 8

Create user login for yourself and then co
ntinue. Here’s a convenient example:

  • Username: master
  • Password: master
  • Hostname: master
  • Login automatically: yes


Step 9

Wait for the whole process while enjoying Trisquel’s beautiful slideshow. This should not take more than about 20 minutes.


Finish

Once finished, Trisquel will say Installation Complete on screen and click Restart Now.


Final Result

Here’s Trisquel 9.0 computer ready to use.

 Enjoy software freedom!

How To Install Ubuntu 20.10 Groovy Gorilla

Friday 23rd of October 2020 04:09:00 PM

This tutorial explains Ubuntu 20.10 Groovy Gorilla computer installation. You will prepare at least two disk partitions, finishing it all in about twenty minutes, and enjoy! Let's start right now.



Subscribe to UbuntuBuzz Telegram Channel to get article updates.


About This Tutorial


This tutorial is practicable for normal installation as well as dualboot, UEFI, and even external drive ways. 

  • Normal: most computer users will need this.
  • Dualboot: users who wants both Ubuntu and Windows in one computer will need this. This needs separate partitions prepared beforehand.
  • UEFI: users with >=2011 computers will need this. This needs one additional partition called efi.
  • External: for users who want to install, not only make bootable, Ubuntu into a pendrive or external hard disk drive. The only difference is where you put the bootloader on.


Preparations


Ask experienced knowledgeable computer users near you guidance in following this if you have no prior experience in partitioning and doing backup.

Partitioning example

First preparation, Download Ubuntu 20.10 and create a bootable flash disk drive using tools like Unetbootin or Rufus, GNOME Disk Utility, or GLIM.

Second preparation, with GParted on LiveCD, create three hard disk partitions: 

  • first one tiniest, a FAT32 by 100MegaByte with label FOR EFI;
  • second one a little bit larger, a FAT32 by 1GB with label FOR SWAP; and
  • third one the largest, a FAT32 by >=20GB with label FOR ROOT.

For Dualboot mode, make sure you properly backed up important data from Windows and its data partitions to external storage drive. For BIOS Legacy users, you do not need and simply ignore the making of EFI partition above. For UEFI users, you do need to make those three partitions. For disk partition size, I recommend a 100GigaByte ROOT for serious and permanent use. For external installation, you can install Ubuntu into a USB Flash Drive or similar device by choosing correct bootloader location as explained in partitioning section below.


Booting & Entering Setup

Make sure your BIOS ready, now boot up your computer to USB > then, select Try It instead of Install It on Ubuntu selection screen > you see a pink orange desktop with a gorilla picture, that is "preview" or LiveCD session, then double click Install Ubuntu 20.10.

 1. Select Language


First page, select English and continue.

2. Select Keyboard


Second page, select English (US) and continue. You can change it later to Arabic, Japanese, Chinese, etc. anyway.

3. Select Networking


Third page, select 'I don't want to connect' and continue.

4. Select Normal


Fourth page, select Normal Installation instead of Minimal and continue.

5. Select Manual Partitioning


Fifth page, select Something Else also known as Manual instead of others and continue. You might be asked to do unmounting then do it.

6. Create Disk Partitions & Bootloader


Here you will utilize 3 partitions you have created beforehand.

  • 1. Create EFI partition(*): click the smallest sized partition > Change > switch Use as: to EFI System Partition > OK.
  • 2. Create SWAP partition: click the middle one > Change > switch Use as: to swap > check mark Format the partition > OK.
  • 3. Create ROOT partition: click the largest one > Change > switch Use as: to EXT4 Journaling Filesystem(**) > check mark Format > select mount point / > OK.
  • 4. Select bootloader install(***): choose the same disk address where you made ROOT partition above, for example, choose bootloader /dev/sda if your ROOT is /dev/sda1.   
  • 5. Click Install Now. 

 

*) BIOS Legacy users do not create this.

**) Choose EXT4 for hard disk, but instead choose EXT2 for installation into USB flash disk. 

***) For external install, do not choose internal hard disk address but choose your external drive address where your ROOT partition is made.


7. Fill User Profile


Here you determine own timezone then username & password pair.

  • 1. Timezone: click a point on the world map to choose yours. As example, mine is Asia/Jakarta, Indonesia. Go next. 
  • 2. Username: determine username > determine computer's name > determine password > determine either Login Automatically to mimic most Windows computers (for convenience) or Login with Password as usually Ubuntu user's do (for security) > go next.


8. Wait


Now you will only need to wait up to fifteen minutes while enjoying beautiful slideshow. You can have a cup of coffee or chit chat with friends here. The secret is, here thanks to you chose Try It (aka LiveCD) earlier, you can even write documents or play audio as you can run all the programs on your screen.


Finish


Once finished, Ubuntu 20.10 says Installation Complete so click Restart Now to enjoy your new computer. Congratulations!

Lenovo ThinkPad Booting GNU/Linux USB

Thursday 22nd of October 2020 01:23:00 PM

Lenovo ThinkPad users can boot USB drives finely. As Ubuntu Buzz often publishes booting articles, now let's learn how to practice that on computers using ThinkPad as example. By making this tutorial I hope I give abilities to all computer users who didn't know yet they can do this amazing thing. Let's go!

Subscribe to UbuntuBuzz Telegram Channel to get article updates.


What Is Booting

Computers work by a mechanism called booting that is finding the storage and reading the operating system. When user starts up his computer he does booting. Operating system is an important software set stored in storage without it computer does not work. On PC and laptop, an OS normally stored in hard disk drive (HDD) however in fact there were OSes stored in floppy disk drive also known as diskette (FDD), in Compact Disc (CD) or Digital Versatile Disk (DVD), and in modern days even in USB flash drive (USB).

What Is a USB Drive

A USB storage device sometimes called USB pendrive, USB stick, or flash disk, or whatever else. It is a digital storage that connects to computer through USB standard.

Goal

To run an operating system stored in a USB drive.

Making Bootable USB

An operating system should be inserted into a bootable drive in order to make computer runs it. To create one, use one of these tools.

 

Insert Drive

Plug your pendrive stick to USB port on your computer.


Start The Computer

Turn your computer on. 

Setup BIOS

(1) Press special key to enter your BIOS. As example, on Lenovo ThinkPad it is F1, on Acer it is F2, and on ASUS it is Del, on your computer it depends on what message appears quickly under manufacturer logo when you boot up.

(2) Go to Booting section and make sure computer chooses USB as its first device to boot before HDD and CDROM. 

(3) Save and Reboot. On most computers, the key is F10.

Run Operating System

Now you see GNU Operating System runs. Your screen should see the appearance of GNU/Linux distro you run. On my example my Lenovo ThinkPad runs Ubuntu.


Shutdown and Restart Quickly

Different to Windows or macOS, GNU/Linux has special keyboard shortcuts called Magic SysRq. It works as long as kernel is staying at the memory and not in panic condition. To shutdown instantly, press Alt+Printscreen+REISUO. To restart immediately, press Alt+Printscreen+REISUB. These Magics work with all Debian and Ubuntu distros family. Known distros without these are Fedora and openSUSE.

For the 20.10 Groovy Gorilla I use the image not officially released yet or more specifically “final freeze” development version. The image file is named groovy-desktop-amd64.iso by size 2.8GB dated 15 October 2020.


Ubuntu Computers


Right now Dell, Lenovo, Star Labs, and LaptopWithLinux sell their Ubuntu PCs and laptops preloaded. We can now purchase ThinkPadand XPS high end laptops with 20.04 LTS. We have choices with LabTop and Clevo lines of laptops preloaded with Ubuntu too. Not only them, fortunately Tuxedo and Slimbook, the vendors who made Kubuntu Focus hardware a reality, sell their computers with Ubuntu preloaded too. We can expect they all OEM vendors will ship Groovy Gorilla as well later. The availability of OEM computers like that will lift the burden on end-users to do manual installation just like what manufacturers do with Windows computers for decades.


Booting


Ubuntu Groovy gives three installation options namely Ubuntu, Ubuntu (safe graphics), and OEM Install (for manufacturers). 


Automatics
Once installed, Ubuntu Groovy just works on my ThinkPad laptop. All hardware detected automatically. This will make Microsoft users happy.
Appearances


Here’s how Groovy Gorilla looks like.


Identity


Ubuntu has unique identity just like Microsoft Windows and Apple MacOS have their owns. Groovy user sees their computer by its looks. Top and left panels with such Yaru colors blended between purple orange. Now all icons are displayed equally without classification into Frequent and All. Now icons arrangements can be drag and dropped manually.



Applications


Just like any earlier Regular releases, 20.10 updates its applications so they are the latest and greatest right now. As you can see below, it brings LibreOffice Seven the greatest Free Libre Open Source Software office suite today along with latest Rhythmbox Player, Mozilla Firefox and Thunderbird, and built-in Ubuntu Desktop Guide.


Now making documents got more excitements thanks to Seven.


Connectivity


Networking works smoothly. Wifi, ethernet, and bluetooth doing their jobs seamlessly on my ThinkPad T430. Everything is instantly detected once Groovy has been installed without requiring additional driver discs or such.

Login Screen
Here's how we logging in to Ubuntu computer on 20.10.


As simple as always without any noticeable changes. However, technically speaking, Ubuntu by default runs under X11 mode while Wayland mode is available to choose from the gear button as depicted in picture above.

Installation


Ubuntu successfully keeps its easy install tradition. Imagine to install an OS only under fifteen minutes, that’s Ubuntu for you, without hassle of separate driver discs neither antiviruses. Groovy finishes very quickly continuing its great tradition.



Resource Utilization


Surprisingly, Groovy uses only about 800MiB memory after a fresh install far better than 1000MiB on the previous releases with GNOME desktop. Its CPU utilization is also quiet.  It even works well on a virtual machine with 2 CPU and 1.5GiB memory done with the friendly tool AQEMU.


ThinkPad Specials 


For Lenovo users especially ThinkPad owners, as i use T430 here's my experience with Ubuntu 20.10. It is a happiness.

  • Touchpad: works.
  • TrackPoint: works, the point and its three red buttons.
  • Keyboard: works, plus Fn and Ctrl keys can be swapped from the BIOS.
  • Fn combinations: work
  • Special keys: everything works: mute, up/down, mic, 
  • Speakers: work, both left and right.
  • Indicators: work, wifi - disk - battery - moon.


Afterword


I am excited to review Groovy. I am satisfied. As we could see in this article, everything just works as expected. I wish you find same excitements with Groovy. What do you think about Ubuntu 20.10, o dear readers?

How To Install QStarDict with English-Indonesian on Ubuntu 20.04 LTS

Saturday 17th of October 2020 04:13:00 PM

There was a really good desktop dictionary program StarDict available on Ubuntu for years. It means a lot for education! Unfortunately, it was no longer available on 18.10 "Cosmic Cuttlefish" and later since it got discontinued. That means 18.04 LTS users can still install it but 20.04 LTS users lost it. Fortunately, we have its modern replacement named QStarDict with same functionalities available for 20.04. This tutorial explains how to get it to your system and supplies example in adding dictionary data and finally how to use it.

 

 Thanks to free software community StarDict now lives again!

Subscribe to UbuntuBuzz Telegram Channel to get article updates.

 Install QStarDict


Do command line below:

$ sudo apt-get install qstardict festival

Add Dictionary Data
StarDict divides its program and its dictionary data to work for you. It means after you install the program you must install the dictionary files yourself. There are so many language files available such as Indonesian-English as well as English-Indonesian since StarDict had been around since very long time. QStarDict works the same way. Here's how to add dictionary data by example Indonesian><English.
  1. Download English-Indonesian dictionary files at GitHub
  2. Extract it.
  3. Copy its folder contents.
  4. Paste them into your ~/.stardict/dic/ folder. 
  5. If it doesn't exist then create it and paste them. 
  6. Correctly placed items look like picture below. 

Run QStarDict


Find QStarDict on your start menu and run it. Picture below shows my QStarDict easily found at Kubuntu start menu, panel, and desktop.


Search A Word


On its window, type a word in English and you see list of Indonesian words displaying automatically on the fly. Try the same thing from the other side Indonesian to English. Picture below shows an example, suppose I don't know the meaning of the word distribution then I type that on QStarDict and I can see the meaning in Indonesian pemberian.


Scan On Screen


This is the coolest feature of QStarDict. 

Open an English webpage and try to double-click a word. Conversely, try it on an Indonesian webpage. To enable or disable this feature, give or remove check mark on Scan option by right-clicking QStarDict icon staying at system tray.

It can also scan document.

Yes, it can scan PDF as well.



Spell a Word with Voice


It is another cool feature of QStarDict as it can speak out loud every English word. For example, Indonesian students can learn English pronounciation word by word at home this way. Do a scan like above and click the speaker icon.


Note: if you don't hear anything, install the package festival as mentioned above.

Afterword
That's all. I hope you enjoy learning languages on computer by using QStarDict. Thank you very much Huzheng for creating StarDict the best desktop dictionary ever. Thank you Alexander for creating QStarDict its continuation. See you on the next tutorial!

Dell Ubuntu, Lenovo Fedora, and Slimbook Elementary OS

Friday 16th of October 2020 03:17:00 AM

This year good news coming one after another. Everything starts with Fedora announcing Fedora on Lenovo ThinkPad laptops, then Ubuntu announcing Dell XPS Focal Fossa, and now elementary OS announcing both Slimbook and Pine64 PineBook laptops. Now everybody globally can find Ubuntu, Fedora, and elementary OS preloaded on branded laptops and PCs. This means GNU/Linux desktop goes mainstream. I am happy to see this. I really want to sum them up in one article so everybody sees these great moment. For everyone who loves Free Software community here's the news for you!


Subscribe to UbuntuBuzz Telegram Channel to get article updates.



Dell XPS and Ubuntu

 

Following Ubuntu LTS release April this year, Canonical, the company behind Ubuntu, announces the availability of Ubuntu preloaded Dell XPS laptop. Read the official news. Visit purchase webpage.



Lenovo and Fedora

 

Following latest Fedora GNU/Linux release June this year, The Community announces the availability of Fedora Workstation preloaded Lenovo ThinkPad laptops. Read the official news. Visit purchase web page. Watch the unboxing video by Fedora leader Matthew Miller.



Slimbook and Elementary OS

 

Following latest update of elementary OS this September, and welcoming the next version 6.0, elementary OS announces a very good news that Slimbook the Apple-like European computer maker now ships their MacBook-like laptops and iMac-like workstations  with elementary OS preloaded. Personally, when I look at the picture for the first time, I think it is pretty suitable for the workstation to have elementary OS and that is exactly what I want to see for years. Read the official news.  Visit the purchase webpage Pro X laptop and Apollo workstation.


Surprise, not only Slimbook but apparently also Pine64 the ARM technology laptops and smartphones maker wants to join the retailer group and will make Pinebook laptops preloaded too. It is still in development between two parties and you with ARM knowledge can participate too before the real shipment begin. What makes Pinebook became a best seller is thanks to ARM technology used you can imagine a standard laptop but with battery efficiency and low weight of a smartphone then no wonder everyone knows wanted it. Before elementary OS, Manjaro has been successfully shipped with Pinebook and we are now wishing the real thing happens soon with elementary. However the photo is already available at elementary website and it is so appealing. Read the official news


Afterword

 

We are glad to see these good news. I agree with what Fedora Magazine said, this is really "good opportunity to grow our community" both in technology and in business. I also agree with Valentin David in his presentation at GUADEC 2020 that GNOME should be "Preinstalled on hardware", citing a GUADEC 2012 quotation, to expand our community further. That's why I see these news all are good and I want to witness more. I wish more computer models will be supported by Lenovo for Fedora, more models for Ubuntu by Dell, and soon the real things will be ready for PineBook elementary OS. Further, I expect ASUS, FUJITSU, TOSHIBA, and other vendors will also join our community to ship GNU/Linux operating systems with their computers. It would be lovely to see greater job vacancies opened thanks to these. Finally, here's my summary I hope you will like it.

How To Use AQEMU Virtual Machine on Ubuntu

Thursday 15th of October 2020 04:19:00 PM

We are fortunate to have a good virtual machine tool AQEMU on GNU/Linux operating systems. With AQEMU on your Ubuntu computer, you can virtualize any operating systems very easily. It can replace and works similarly to the proprietary tool VirtualBox or VMWare step by step as you can see in this tutorial. Now let's learn virtualization!

Subscribe to UbuntuBuzz Telegram Channel to get article updates.

What Is Virtualization


Virtualization is running an operating system on top of other operating system. The result is two or more operating systems running at the same time. To do virtualization, people use tools like Xen, VirtualBox*, VMWare*, Fusion*, or Virtual PC*. However, GNU operating systems with Linux kernel have advanced virtualization technology named AQEMU which is a complete solution similar to VirtualBox or VMWare. In a virtualization, the OS that runs the virtual machine called host or hypervisor, while the OS that is running in that virtual machine is called guest.

*) Proprietary software.


Summary

 

To do virtualization with AQEMU you will do 5 steps:

  • 1) Creating a new virtual machine.
  • 2) Creating virtual memory.
  • 3) Creating virtual hard disk drive.
  • 4) Adding OS image.
  • 5) Run virtual machine.

 

Get AQEMU


On Ubuntu operating systems, you can get it from Software Center. Example below is AQEMU found in Discover the software center on my Kubuntu computer.


Run AQEMU


Find AQEMU blue logo on your start menu and run it.

Example above is AQEMU found on Kubuntu start menu and also appeared on desktop wallpaper area. That means AQEMU has been installed on my Kubuntu computer. The start menu has been changed into classic style and AQEMU is located under System category. Your GNU/Linux computer should lookssimilarly.


Initializing AQEMU


Before anything, when you first launch AQEMU, you should do the initial setup. It asks you two things which are first create a hidden directory for everything, and second find the actual QEMU installed program on your system. Important: it is better to choose directory path in the largest free space disk drive you have as virtual hard disk files will be stored in this directory by default.


  1. By default, AQEMU displays a .aqemu folder path which is located in your home directory. In this example I let it be the default which is located in my home directory in my 20 GB filesystem disk drive. Click Next.

  2. It asks for where the QEMU program is exactly located in your computer. Click Search button and it will instantly find them. For example, in my Kubuntu they are located in two folders /usr/bin/ and /bin.

  3. It shows “finished” message. That means everything is okay and now you are ready to do virtualization.

  4. Successful AQEMU initial setup will look like picture above. It is AQEMU window with all buttons and an empty virtual machine list with all tabs displayed vertically.


1. Creating a Virtual Machine


First thing to do is creating a virtual computer or also known as a virtual machine.


  1. Go to menubar VM > Add VM > Add New VM > first page showing choices > select Typical > go Next.

  2. By default, AQEMU supports four different operating systems which are GNU/Linux, FreeBSD, Windows, and MacOS plus ability to generate your own support for another OS if you wish. Because this tutorial wants to virtualize Trisquel which is GNU/Linux, we will select Linux 2.6 template. On this second page, select Template > select Linux 2.6 > go next.

  3. On the third page, select KVM > go next. If you cannot select KVM here, enable Intel-VT or AMD-V virtualization feature on your BIOS and try again.

  4. On fourth page, give name to your virtual machine. Name it gnu. Go next.

  5. On fifth page, determine how much virtual hard disk size for your virtual machine. Normally GNU/Linux desktops are fine with just 20 GB. This hard disk is represented as file by size you chose in your computer hard disk drive. Go next.

  6. On sixth page, so that your guest OS can connect to the internet, select User Mode Network and go next.

  7. Finished everything on seventh page. Now click Finish.

  8. AQEMU with one virtual machine created will look like this. Pay attention to the five tabs presented vertically [Info] [VM] [Media] [Display] [Network].


2. Creating Virtual Memory


Second thing to do is determining how much memory for your virtual machine taken from your real computer memory. Select your VM name gnu > open the tab [VM] > set the memory to 1500 MB > Apply. 


By making virtual memory, your computer will share several GB memory for host and several GB other for guest. Bigger memory size means more applications to run on the guest but also fewer task can do on the host. For virtualizing modern operating systems like Ubuntu Desktop and Microsoft Windows, today >=1.5 GigaByte or 1500 MegaBytes virtual memory is good. For lightweight and old operating systems like Lubuntu or Windows 98, half gigabyte or >=512 MegaByte is enough. For example, as I want to run Trisquel 9 Etiona which runs well under 1GB memory, I determine here 1.5 GB for virtual machine so my host computer still has the rest 2.5 GB.


3. Creating Virtual Hard Disk


Thirdthing to do is creating a new virtual hard disk. Imagine this as hard disk drive where you install the operating system into. If you already made your virtual hard disk in previous step, skip this. If you want to change or move it to another disk partition, do this. 


  1. First thing is to see whether your VM has a virtual hard disk or not. Select your VM name from the list > open the tab [Media] > your virtual hard disk should exists there with the name HDA (/path/to/file). If it does not exist, or if you want to change it, go to next step. If you see everything is OK, skip this section and go to next section.

  2. To create new one, select existing HDA > click Manage Devices Properties (pen on paper button) > Properties dialog appears > click Create (green plus button) > Create dialog appears > click Browse > name the virtual disk image file > place the image file in computer disk drive with most free space > OK > select Format: qcow2 > determine size 20 GB > click Create. For example, I placed my file in my data partition New Volume (/media/master/New Volume/gnu-virtual-hard-disk-drive.img).

  3. A dialog appears informing that the virtual hard disk drive creation was created successfully.

  4. You went back to Properties dialog. Here you see your virtual hard disk drive image file is correctly located in the path you have created. In my example, it is /media/master/New Volume/gnu-virtual-hard-disk-drive.img. Close Properties dialog.

  5. AQEMU with a virtual hard disk drive set properly.


4. Adding OS Image


This is where you insert operating system image file you desire. For example, here I insert Trisquel GNU/Linux. The file extension is .iso by size 1.7GiB and my Kubuntu categorized it as raw CD image as you can see below.

  1. Make sure you know where you store the OS image file. For example, my Trisquel image by 1.7GiB size is stored in Downloads folder in my home directory.

  2. Go back to [Media] tab > click Add Devices CD (CD button) > Properties dialog appears > click folder button > Open File dialog appears > browse and find the image file > select the image file > Open > you went back to Properties dialog > OK.

  3. AQEMU with a virtual hard disk drive and an ISO image file means ready to run virtualization.


5. Running Virtual Machine


Select your VM name > go to menubar VM > Start (Ctrl+S). Now you should see the operating system runs. This results in two operating systems running where one as host and another one as guest. In this example, my Kubuntu is the hostwhere my Trisquel is the guest. This is the stage where you start the fun. You can install the operating system or simply preview it (LiveCD). For Windows and macOS and alike they can only be installed and cannot be previewed. But for GNU/Linux OSes they can be installed as well as previewed (LiveCD) and my Trisquel is one.



6. Stop Virtual Machine


To stop virtual machine, go to virtual machine window menu bar Machine> Power Down. To restart, select Resetinstead of Power Down. Alternatively, inside the virtual machine simply use Shutdown or Restart button available on the operating system. It is just like real computer, you can rebootor shutdown it.

 

Afterword


That’s all with AQEMU use basics. Thisdoesn’t give you more techniques like USB connectivity or advanced ones like networking but I wish it’s enough for beginners to start their virtualization life. By making this article I want people to recognize the free software AQEMU as the alternative to the proprietary VMWare or the – unfortunately– currently nonfree VirtualBox. 

 

My Lenovo ThinkPad and Ubuntu

Wednesday 14th of October 2020 03:55:00 PM
At Saturday 10 October 2020 finally I purchased Lenovo ThinkPadthat I wanted for a long time. It replaces my old laptops Asus and Acer which are already unusable for all my works especially here at Ubuntu Buzz. Now I have a decent computer to write Ubuntu articles I love here. As an avid Ubuntu user, of course I tested it immediately with 20.04 and it made me so happy everything runs faster and better. I feel it is perfect. It is a T430 from 2012 with Intel Core i5 and four GB memory and 320 GB hard disk drive plus its trademark red trackpad and everything else. I found it new by price Rp2,5 millions or roughly $169 so I think I’m lucky. I now can recommend ThinkPad to everyone especially those who want laptop to run GNU/Linux and Free Software. To share my happiness with you, below I listed details of my ThinkPad with important notes.

My Thinkpad Summary


It is dream comes true laptop to me. Its design looks cool. It works perfectly with latest Ubuntu and Kubuntu LTS. It works very well with latest Trisquel Etiona too but the wifi does not work along with the bluetooth. The display is just like what I want a fine non shining one so now I can photograph my display just fine. The important part is my ThinkPad does not have NVIDIA Geforce nor ATi Radeon which makes me very happy I feel free from troubles. It lasts for 3.5 hours according to my test at its first days which is very good for me.


Specification


  • Processor: Intel Core i5
  • Memory: 4GB
  • Hard disk drive: 320GB
  • Video card: Intel HD Graphics 4000
  • Booting firmware: UEFI and BIOS Legacy 
  • Ethernet: Intel Gigabit
  • Wifi: Intel Centrino Advanced-N 6205
  • MMC/SD card port: yes 
  • Bluetooth: yes
  • CDROM: DVD+-RW Ultrabay

How To Install Ubuntu With ‘D Drive’-like Data Partition

Monday 12th of October 2020 03:18:00 PM

Actually it is very easy to install Ubuntu alike operating systems with data storage partitions similar to Drive D: to mimic tradition of Windows computers. What you need to do is just install Ubuntu like usual but create one additional large partition without attaching mount point to it. The result is you will always see one data partition ready to use just like you usually found while using Windows. Just because apparently many people asked it then I make this tutorial to help. As stated it is for Ubuntu alike, you can also practice this to Fedora, openSUSE, Manjaro, and others.

 (A Kubuntu laptop with New Volume displayed as data partition)

Preparations


Prepare separate disk partitions. Don’t just create system partitions, but also create data partitions. This kind of setup is actually what traditionally Windows Computers are where C is for system and D is for data.


Installation


Do operating system installation like normally we do it. But the only difference is let the data partition without mount point. If you don't know how, here are installation guide examples which includes explanation on dualboot and uefi modes:

 

Finish


Finish the installation like usual. Nothing special.

Error Messages


Here is the error message you may encounter:

W: Failed to fetch [URL] Unable to connect to [URL]
W: Some index files failed to download. They have been ignord, or old ones used instead.

Picture below shows the error my computer experiencing:

Cause


In my case, it is caused by my repository is no longer working anymore. Inactive repository makes your Trisquel computer unable to get software and updates resulting to error above.  (To my inactive repository''s maintainers in India I say my gratitude and respect you gave me greatest things ever on computing.)

Fix


Change your download source from the inactive one to an active one. To do so, open Software & Sources > click the Download from button > click Select Best Server > wait for a while > finally pick the one that selected automatically by the computer. For example, in my case as I live in Indonesia, computer picked me the United States one as the fastest for me. See picture below.

Then simply do a reload or $ sudo apt-get update command line. Fixed Trisquel computer in this case should shows normal output lines without error message above like picture below. You can even see download speed, size, and time.

Proof

 

Test it! Try to install a new application. In my computer, I tried to install KeePassX a nice password manager and it works successfully. You can do it either by Synaptic Package Manager or command line $ sudo apt-get install keepassx .

Have a nice day!

Save Webpages You Care About to Archive.org

Wednesday 7th of October 2020 04:34:00 PM

Archive.org is the time machine of the internet. You can find on it any web page ever published since 1996. Think Google but you can go back to any point in history of every result. You can also be part of the time machine or contributing to it. This article invites you to try The Internet Archive and contribute by saving pages you love to be a history everyone can read. Believe me it is fun!

Subscribe to UbuntuBuzz Telegram Channel to get article updates.What Is Archive.org? 

Go to www.archive.org it is the Internet Archive. It currently holds 400 billions web pages according to Wikipedia as well as three millions movies, four hundreds thousands of computer programs, and seven millions audio files. Yes Internet Archive is not only a search engine, but also a giant storage of digital files. The point in this article is that Wayback Machine, the time machine within Internet Archive, can bring us back to a point in history for any web page ever published. That means it can reveal dead websites too. You can imagine how much benefits you can get from using it correctly, say, for historical or even crime proving purposes.


Wikipedia Uses Archive.org 

Ever read Wikipedia's references? You might saw links that followed by words "archived from the original" and if you follow the link you'll find the web page in a point in history. If you look closer, actually archived web pages there are in the Internet Archive. Check for example references on Ubuntu. That's an excellent example how Internet Archive benefits us.

Searching

 

Type the address of website you like in www.archive.org. Then you will see history of that website saved within Internet Archive. For example, if you enter the address ubuntu.com you can see history of Ubuntu website from time to time since first introduction 2004. Try other websites too!

1) Go to Internet Archive

2) Search for ubuntu.com like below. This is an example. You can type any other web URL address.

3) You see full history of ubuntu.com web page shown as a calendar. There are blue and green bubbles showing when the time Internet Archive saved them.



4) Pick one history point available among the colored bubbles. You can also see the Internet Archive's URL address of that page. Feels familiar? Yes, it is how Wikipedia gets its archived references.

5) You see ubuntu.com website in that point of history. Here is Ubuntu website in 2006 as is without any alteration saved perfectly by Internet Archive.

Quick Search

 

You can do searching above without visiting archive.org. Visit a website and click the button to see its history or last archived instantly from the Internet Archive. Very convenient, right? See last section to get that button on your web browser.


Is A Web Page Archived?

You can see whether a webpage you visit is already archived or not. Also, you can see whether the archive is up to date. Later on, you can contribute to the internet history by helping save web pages to Internet Archive! To check a web page, click the button and let it loads a bit to see last archived date.


Saving


Everyone can archive webpages to the Internet Archive! Visit a webpage and click Archive Page button and it archived instantly. As a result, now everybody can visit the webpage's history on the Internet Archive. You can share the URL address to your friends. You can repeat this process to any other web page. Pretty interesting, right?


The Button 

Actually it is an addon called Save To The Wayback Machine. that can be installed to Mozilla Firefox. Go to the addon page and click install there and voila you got the button we discuss above. Following picture is the screenshot of addons installed on my web browser and the emphasized one is the Save To. That's all. Finally, I hope you find fun learning internet history!

Happy archiving!

What To Do When Your Computer Fails

Tuesday 6th of October 2020 02:39:00 PM
This is a note I took based on my experience with computer failure. You can imagine worst situation when everything is closer to an end. It feels frustrating and can lead to despair. You may already found the signs that your hard disk drive, display, touchpad, USB ports, are already in worse condition. Before your machine die for sure, you can learn something from my reflections below as now mine died. It died after worked for me since 2016 almost nonstop everyday. I hope you would never experience any of my story and only got solutions and the good things if anytime things going worse.

Keep Your Mind Calm
From freedom came elegance. From calm came reasons. From patience came solutions. When I got a trouble I keep talking to myself to calm. Only calm mind can solve a thing. Anger or despair alone cannot. I do not have particular attachments to slogans but GNU/Linux Mint’s slogan came first while I writing this so I put it here and thank you Clement Lefebvre!
Purchase A Capable Computer
First thing is to have a good computer. This is a thing we should do far before everything. A good one is a durable, tested, well acknowledged by capable people. I know I admire Purism Librem laptops until I think to have one, as well as System76’s and Entroware’s but they are expensive to me for now (with respects to them). For my next life, personally I wish I could buy Lenovo Thinkpad for sure as a replacement to the broken one. For a long time I learn about Software Freedom it is Thinkpad that is often praised by activists, and even more awesome than that, all certified laptops by Free Software Foundation in their Respects You Freedom are Thinkpad. I wish that for not only the hardware quality but also the best compatibility to GNU/Linux operating systems compared to other brands. Currently I see either the T430 or the X200 family is desirable. With a good computer you will find good life just any other people for decades long.
Backup
The failed part of my computer is hard disk drive. The problem is that all my data is there and no backup. I regret I didn’t do backup. My excuse is reasonable as I do not have external storage to store copies of files I have as they are gigantic. If only I had a spare external disk drive, I would had them all backed up right away. For my next life, I think I should encrypt all my data in a compressed archive and upload them anyway to online storage (perhaps multiple of them) I trust.
Fix Charger, Don’t Overcharge, Don’t Undercharge
This is electricity trouble. It was already a solved issue for me but when I got this trouble it was devastating. I could not work at all. I could not teach either. If you ever find anomaly with your charger, buy a new one correctly (expensive) or go to an electro technician to fix it up (cheap). I did the latter and it was really a solution. If you live with batteriess, don’t overcharge and don’t undercharge either. Overcharge by keep charging even though battery is full. Undercharge by keep using computer until it runs out of power without shutdown. Overcharge is bad to your battery. Undercharge is bad for your hard disk drive and your data.
 Use Non Journaling Filesystem
I believe I must use ext II for my next hard disk drives and not ext IV. I am a person who do not need much technology so even old one but works well (and prolongs my disk drive lifespan) will sufficient to me rather than the new ones that not. I am not interested in butterfly or cow. You cannot save anything if the hardware itself fails. I work heavily (much more heavier than average people) in data so filesystem that writes less is better than filesystem that writes more. Ah, and, actually my hard disk drive mentioned above is a solid state disk. I already used this trick for my SanDisk usb flash drives as I do not have spare storage I use them instead as places to install operating systems I was reviewing and as I said they work very well. 
Do Not Throw Away Components
Before this case, I already had another broken laptop, my first one. Fortunately I didn’t trash it. It is Asus X44C but it has a component worth keeping that is Atheros wifi compatible to Trisquel. It is truly a blessing. It means I can swap it (“cannibal”) to another laptop and I can run any of all GNU/Linux distros works with the wifi out of the box without worries. There are some possibilities other componets still worth keeping too, say, the LCD monitor can be sold with good price. 
Don’t Overheat
Heat kills. Overheat can destroy your hardware. I believe one of the causes of my hard disk drive failing is heat as Indonesia got very hot lately at noon and in fact this computer is already old. I do have a small usb fan but I don’t use it often as the cable is too short and my touchpad is unusable. For my next life, I plan to purchase a decent usb fan worthy for my laptop.
Don’t Use Failing Dongles
I have a reliable usb wifi I used for years. I like it. It was truly convenient. Unfortunately around the rising of Corona it showed anomaly so bad it made every of all operating systems I use (GNU/Linux) need to be forced shutdown. The worst, it occured very often randomly without predictable pattern and when it occured I always couldn’t do reboot or even reisub to save health of my hard disk drive. Since I removed it such problem never occurs again. I believe it was caused by either hardware bug or some physical failure. If you have failing dongle like that, stop using it, replace it with a new one if you can.
Buy Keyboard Immediately
If your keyboard shows signs of breakage, replace it right away. No matter whether you are an author like me, online teacher, programmer, designer, government worker, or simply computer user, your keyboard is your computing life. It is not a problem in my current case, but I had experienced broken ones three times, and every time it was disaster. Trust me it is counter-productive.
Bubble Wraps
It is a good idea to layer the inner parts of laptop bag with bubble wraps. Bubble wraps are shockbreakers. No matter it is ssd or hdd inside, your laptop deserves safety from shocks and bubble wraps can help and they are very cheap. Use some simple adhesive tapes to install them.

Summary
It is good to have good computer since the beginning. Whenever a hard disk starts failing, do not wait to backup. Whenever we can afford to buy good computer or replacing peripherals, do it immediately. Finally, I wish you all good computing life!

Richard Hughes: fwupd 1.5.2

If you’re running 1.5.0 or 1.5.1 you probably want to update to this release now as it fixes a hard-to-debug hang we introduced in 1.5.0. If you’re running 1.4.x you might want to let the libcurl changes settle, although we’ve been using it without issue for more than a week on a ton of hardware here. Expect 1.5.3 in a few weeks time, assuming we’re all still alive by then. Read more

Xfce Virtual Machine Images For Development

The openSUSE distributions offer a variety of graphical desktop environments, one of them being the popular and lightweight Xfce. Up to now there was the stable tested branch available in Tumbleweed already during install. Furthermore, for interested users the development OBS repository xfce:next offered a preview state of what’s coming up next to Tumbleweed. Xfce Development in openSUSE Thanks to the hard work of openSUSE’s Xfce team there is a third option: Xfce Development Repository aka RAT In a playful way, a rat is meant to represent the unpolished nature of this release: a rat is scruffy looking compared to a mouse (the cute and beloved mascot of Xfce). And the RAT repository provides packages automatically built right from the Git Master Branch of Xfce upstream development. The goal of this project is to test and preview the new software so that bugs can be spotted and fixed ahead of time by contributing upstream. The packages pull in source code state on a daily basis and offer a quite convenient way to test and eventually help development. So this is where the team builds and tests the latest and unstable releases of Xfce Desktop Environment for openSUSE. Read more

Radeon RX 6800 Series Performance Comes Out Even Faster With Newest Linux Code

Last week we delivered AMD Radeon RX 6800 / RX 6800 XT Linux benchmarks and the performance was great both for Linux gaming as well as the OpenCL compute performance. But for as good as those Big Navi numbers were on the open-source Linux graphics driver stack, they are now even better. That launch-day testing was based on the Linux state in the second-half of October when the cards arrived and initial (re-)testing began in preparing for the Radeon RX 6800 series reviews -- not only the Radeon RX 6800 series but re-testing all of the other AMD Radeon and NVIDIA GeForce graphics cards for the comparison too. Thanks to the rate of the open-source graphics driver progression and the newest code always being available, now just days after launch the numbers are even more compelling for Linux gamers with the slightly newer Linux 5.10 and Mesa Git compared to just weeks ago. In particular were the last minute NGG fixes and other Big Navi tweaks along with an important Radeon RX 6800 (non-XT) fix. There has also been other RADV improvements and more that accumulated in Mesa 21.0-devel this month. On the kernel side, Linux 5.10 is still at play. Both the old and newer Mesa snapshots were also on LLVM 11.0. Read more Also: Intel: AMD Gimps On Battery-Powered Laptop Performance - But DPTF On Linux Still Sucks - Phoronix
