Most of the performance changes to be found between Mesa 10.1 stable and the current Mesa Git code just past the 10.2 branching was around the HD 7850 graphics card that uses the RadeonSI Gallium3D driver while the other three graphics cards used the R600g driver. With R600g and our assortment of Linux gaming and OpenGL benchmark tests run, we didn't see any better performance in the code beyond where it's at with Mesa 10.1.
Every now and then, Canonical issues Linux kernel updates for all the operating systems that are being supported at that time. In this case, there are five distributions that have received this new upgrade, but it's interesting to note that not all the OSes share the same kernel, which means that it was a problem common to all, regardless of the version.
In order to install Linux from a bootable USB stick I need to be able to get to the Boot Selection menu, but on Acer systems with UEFI firmware, this is a bit tricky. The Boot Menu key (F12) is disabled by default, so I first have to boot to the BIOS Setup Utility, by pressing F2 during the power on or reboot cycle. Then in the Main setup screen there is an option to enable "F12 Boot Menu".
That's one trick down, but there's another one which might be required. Depending on what version of Linux you want to install, and perhaps how you feel about Secure Boot, you might want/need to disable that. In the BIOS Setup Utility, on the Boot menu there is an option to disable Secure Boot - but I can't get to it: moving the cursor down just skips over it!
I can change boot mode from UEFI to 'Legacy BIOS', but that isn't what I want to do. I learned (the hard way) with my previous Acer Aspire One, that I have to go to the Security menu and set a "Supervisor Password" before it will let me disable Secure Boot mode. I'm sure this makes sense to someone, but whoever that is, it isn't me.
In this case I am going to start by installing Linux with Secure Boot still enabled, so I don't really have to do this, but I went ahead and set a supervisor password anyway, because I will eventually want to turn off Secure Boot anyway.
Telegram is a messaging application similar to WhatsApp and uses the internet to send and receive messages between its clients. We, Linux users, love open source products and Telegram founders claim that they will eventually open source the code. More on this can be read from “Why not open source everything? . Apart from the open source affinity, a few more reasons to use Telegram are :
cross platform compatibility

Ubuntu 14.04 has now been released. It is one of the biggest milestones for Canonical before it moves towards full-fledged convergence. Being an LTS release, Ubuntu 14.04 Trusty Tahr focuses on security, stability, and performance. It builds on all the previous Ubuntu releases and makes sure that it makes up for as much technical debt as possible.
Ubuntu fanboys and fangirls are definitely impressed about this release. After all, Trusty Tahr is probably the most trustworthy release coming out of Canonical. We too are excited about the new changes. That's why, we've compiled a list of some of the most compelling reasons that make Trusty Tahr better than previous versions of Ubuntu.
Lubuntu 14.04 LTS Trusty Tahr is an official derivative of Ubuntu 14.04 LTS based on the Lightweight X11 Desktop Environment (LXDE). On this release, as the Xubuntu 14.04 Trusty Tahr, Lubuntu 14.04 also come with LTS version, it mean will be supported for 3 years.
With aims to provide a very lightweight distribution, complete, easy to use for desktop and very functional operating system, Lubuntu 14.04 LTS trusty tahr can work on old or low-resource PC and laptops that meets the minimum requirements because the LXDE desktop environment that used lubuntu is very light, optimized and easy to operate.
For the longest time, Ubuntu Unity users have wanted a bit more leverage from the Unity Launcher. As it stands, it's a means to launch applications and get to the Unity Dash. But with the creation of a new tool, Drawers, you can easily organize related items (files, applications, websites, folders, etc.) using "mini dashes" and "quick lists" -- similar to the Stacks feature in OS X. Drawers allows you to organize files together onto the Launcher and even create a Dash-like app menu for quick access to your applications.
For now, the Linux kernel available is 3.13.x, which is the same from Ubuntu 14.04 LTS. The system is basically identical with the previous one, even if there are some changes that have been implemented already.
“Our Trusty kernel has been pocket copied to seed Utopic. We have opened the ubuntu-utopic kernel tree. The master-next branch is currently tracking the v3.15-rc3 kernel. We likely won't upload a v3.15 based kernel until a few more -rc releases come out,” said Canonical’s Joseph Salisbury in the mailing list.
Xubuntu 14.04 LTS Trusty Tahr is an official derivative of Ubuntu 14.04 LTS, released with many improvement and updates. Come with LTS (Long Term Support) version Xubuntu 14.04 will be supported by xubuntu team and developer for 3 years. Without adding tons of new features, Xubuntu focuses on stability, simple, light and fully customizable.
Xubuntu 14.04 LTS Trusty Tahr uses the Xfce desktop environment instead of Unity 7, so it works very well as a lightweight alternative to regular ubuntu desktop. On this release Xubuntu developers have introduced the new Whiskermenu a more modern menu with the ability to easily launch your favorite applications, as well as have a useful search bar and various customizations. You can also find the new Xfwm4 4.11 which includes support for Sync VBlank, Xfdesktop 4.11 and other updates.
That means that if you use Ubuntu 12.10, you should upgrade to Ubuntu 13.10 (Ubuntu 13.04 has already reached end of life) and then (recommended) to 14.04. That's because after May 16 2014, "Ubuntu Security Notices will no longer include information or updated packages for Ubuntu 12.10".
It's also important to mention that PPA maintainers will no longer be able to upload packages for Ubuntu 12.10 after that date.
Everyone knows that Ubuntu is not one of the most customizable operating systems, which is one of the problems that often come up in the Linux community. This is where the Ubuntu Tweak software will really help its users make head or tails of the Ubuntu Linux distro in a way that very few applications can.
The idea was audacious: Combine Android, the most popular mobile version of Linux, with Ubuntu, the leading Linux desktop operating system, on a single smartphone that swapped between the two depending on whether the device was docked. Alas, Ubuntu for Android seems to have moved off the active roster as Canonical focuses on its own Ubuntu Touch project, and a new exchange on a Ubuntu project-tracking website seems to suggest Ubuntu for Android may be dead. (See update below.)
Linus Torvalds is back in the news, but this time it's good. Torvalds tops the news tonight for being the recipient of a prestigious award. LibreOffice 4.1.6 was released today with about 90 fixes and squeezably fresh Tails 1.0 is making headlines. And our final story tonight, The Register is reporting that upgrading Ubuntu 13.10 to 14.04 "may knacker your Linux PC."
Ubuntu for Android sounds like a great idea. According to the official website, Ubuntu for Android provides a full desktop experience, including office software, web browsing, email and media applications, on Android phones docked to a screen and keyboard.
Canonical didn't put too much effort in this project after it was officially announced and besides a vague late 2012 launch date, there is not much information about it. Users don't even have access to a Beta and they can't really test it.
The Ubuntu developers have already started working on the next Ubuntu version, and the first development images have been produced. Don't expect too much from the new Ubuntu build, at least not yet. It will be a couple of months until some major changes are visible.
If you boot it right now it still says Ubuntu 14.04, so you can see that this is only a placeholder for the features that will get implemented along the way.
With Ubuntu 14.04 LTS there is improved support for multi-GPU laptops (commonly what's branded as NVIDIA Optimus configurations) where there is a discrete NVIDIA GPU used for high performance workloads to complement the low-power Intel integrated graphics. Ubuntu 14.04 LTS features better support for these Optimus / DRI PRIME configurations on both the open and closed-source graphics drivers. Here's the Ubuntu 14.04 multi-GPU experience along with some OpenGL benchmarks and power consumption numbers between the different configurations.
Now that Ubuntu 14.04 LTS is out the door, I tested it out on a ASUS Zenbook Prime ultrabook with an Ivy Bridge class Intel Core i7 3517U CPU that has HD Graphics 4000 plus a discrete NVIDIA GeForce GT 620M 1GB GPU.
