Optimised authentication methods for Ubuntu Desktop

Filed under
Ubuntu

Still counting on passwords to protect your workstation? When set up properly, alternatives to passwords provide a streamlined user experience while significantly improving security. These alternative authentication methods can also easily be combined to create a custom and adaptive authentication profile.

This whitepaper introduces three popular authentication methods that provide a solid alternative to passwords. Perhaps you’d like to configure your laptop for login using a YubiKey hardware token connected to a dock. Another option could be to login with a Duo push notification when not connected to the dock, but use a Google Authenticator one-time password when no network is available. Maybe you need a separate hardware token just for ssh authentication, and you always need to keep a long, complex password for emergency authentication should all other methods fail. All of these scenarios can be easily configured within Ubuntu.

Debian vs Ubuntu in 2020- The Ultimate Showdown

Filed under
Debian
Ubuntu

As a computer software distribution package, Ubuntu and Debian are utilized in two ways...

Desktop Operating System
Server

Although they are similar in many ways, they have their differences. Ubuntu is based on the testing branch of Debian and often, Debian involves too many manual works and so it is not recommended for beginners. While Ubuntu is easy to use for beginners, it is not as stable as Debian in its built. Let us have a comparison between Debian vs Ubuntu.

Ubuntu MATE 20.04.1 for Raspberry Pi Now Has a Second Beta Ready for Testing

Filed under
Ubuntu

Martin Wimpress published a new beta version of the upcoming Ubuntu MATE 20.04.1 images for Raspberry Pi devices, which you can download and test right now on the tiny computer.

Ubuntu MATE 20.04.1 for Raspberry Pi promises major new features, such as support for the latest Raspberry Pi 4 SCBs, better graphics, experimental USB booting, basic rendering for the Firefox web browser by default, support for the rpi-eeprom utility for updating the Raspberry Pi 4 bootloader EEPROM, and a new configuration tool.

Based on the recently released Ubuntu 20.04.1 LTS (Focal Fossa) operating system, the upcoming Ubuntu MATE 20.04.1 for Raspberry Pi release is now in its latest stages of development, with a second beta version ready for public testing.

Since beta 1, the team fixed Wi-Fi issues that occurred on the first boot during the initial setup wizard and dropped the gpu_mem memory option that lets you specify how much memory the GPU can use from the config.txt file for better performance.

The beta 2 is also powered by the same Linux 5.4 LTS kernel used in Ubuntu 20.04.1 LTS, and uses the latest MATE 1.24 desktop environment and most the core apps that are also available in the Ubuntu MATE 20.04.1 LTS release for PCs.

Ubuntu 18.04.5 LTS Released with Linux Kernel 5.4 LTS from Ubuntu 20.04 LTS

Filed under
Linux
Ubuntu

Ubuntu 18.04.5 LTS comes six months after the Ubuntu 18.04.4 LTS point release and two and a half years after the release of Ubuntu 18.04 LTS (Bionic Beaver), which is normally supported until April 2023, though the end of life is planned for April 2028 due to Canonical’s new 10-year support policy.

The good news for those still using Ubuntu 18.04 LTS (Bionic Beaver) is that Ubuntu 18.04.5 LTS brings yet another kernel and graphics stacks bump. This time, it runs the Linux 5.4 LTS kernel and Mesa 20.0.8 graphics stack from Ubuntu 20.04 LTS (Focal Fossa).

Debian and Ubuntu Leftovers

  • Jonathan Carter: GameMode in Debian

    About two years ago, I ran into some bugs running a game on Debian, so installed Windows 10 on a spare computer and ran it on there. I learned that when you launch a game in Windows 10, it automatically disables notifications, screensaver, reduces power saving measures and gives the game maximum priority. I thought “Oh, that’s actually quite nice, but we probably won’t see that kind of integration on Linux any time soon”. The very next week, I read the initial announcement of GameMode, a tool from Feral Interactive that does a bunch of tricks to maximise performance for games running on Linux.

Ubuntu 18.04.5 and 16.04.7 LTS Release Candidate ISOs Now Ready for Public Testing

Filed under
Ubuntu

After last week’s release of Ubuntu 20.04.1 LTS as the first point release in the Focal Fossa series, Canonical is now working on new point releases for its long-term supported Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 16.04 LTS (Xenial Xerus) operating system series.

Your reaction right now would be like… wait, Ubuntu 16.04.7? Why? Aren’t there only five point releases during the life cycle of an Ubuntu LTS series? Yes, you’re right, Canonical usually bakes only five ISO point releases for each LTS series, but sometime they have to release emergency ISOs because of some nasty bugs.

It happened last year with Ubuntu 16.04.6 LTS and Ubuntu 14.04.6 LTS (now ESM) to patch a critical security vulnerability in the APT package manager, which allowed attackers to execute code as root or possibly install malicious apps and crash the system.

Ubuntu

As you should probably know, Linux powers the majority of the web we see today. This is mainly because Linux systems are inherently more secure and stable than other systems. There are several types of Linux distributions for powering servers. Some notable ones include Ubuntu, Red Hat, Debian, and CentOS. Ubuntu, in particular, has been enjoying a surge in popularity as a server distro in recent times. In this guide, our editors have outlined why the Linux Ubuntu server is outgrowing many of its competitions. Stay with us throughout this guide to learn why Ubuntu shines as a server distro.

AMD Ryzen Embedded SBC Review with Ubuntu 20.04

Filed under
Reviews
Ubuntu

DFI GHF51 Ryzen Embedded SBC runs about as well in Ubuntu 20.04 as it does in Windows 10. Everything basically works and performs well. Our testing shows AMD Ryzen Embedded R1606G processor to offer slightly better performance than the top of the line Intel Gemini Lake Pentium J5005 processor.

I also had one of the same issues as in Windows: one Seagate USB hard drive would not work reliability at all with transfer stalled. That’s probably just a hardware incompatibility, as the drive works with other platforms, and other USB storage devices achieve normal performance when connected to DFI SBC. I also noticed some artifacts with one 3D graphics benchmark, but those did not show up in other 3D accelerated programs.

DFI GHF51 is an impressive piece of hardware as it packs lots of CPU and GPU power in a form factor similar to Raspberry Pi 4 SBC. I’d like to thank DFI for sending a review sample. If you plan to buy in large quantities to integrate the board into your product, you could contact the company via the product page. It’s used to be available as a sample on the company’s DFI-ITOX online store for $378, but it has been taken down since last time.

Open Hardware: Arduino, RISC-V and 96Boards

  • Arduino-controlled robot arm is ready to play you in a game of chess

    If you’re tired of playing chess on a screen, then perhaps you could create a robotic opponent like Instructables user Michalsky. The augmented board runs micro-Max source code, enabling chess logic to be executed on an Arduino Mega with room for control functions for a 6DOF robotic arm. The setup uses magnetic pieces, allowing it to pick up human moves via an array of 64 reed switches underneath, along with a couple shift registers. The Mega powers the robot arm accordingly, lifting the appropriate piece and placing it on the correct square.
