Ubuntu 14.04 LTS 32-bit vs. 64-bit Performance

Filed under
Ubuntu

Going back years we have run 32-bit vs. 64-bit Linux benchmarks. While the results seldom change, we keep running them as the question of choosing between a 32-bit and 64-bit Linux distribution image is still a popular question... These tests drive in a surprising amount of traffic and I continue to be flabbergasted by the number of people still asking this question when nearly all modern x86 Intel/AMD hardware fully supports x86_64 and it generally means much better performance. Usually the only caveat in not using a 64-bit Linux image is if running a system with less than 2GB of RAM.

Ubuntu AIO DVD (all-in-one), a collection of the most important Ubuntu 14.04 LTS flavors made available on April 17, 2014, is now ready for download.

Filed under

One of the best reasons to upgrade to Ubuntu 14.04 LTS is by far the new Linux kernel stack that comes with the new version. Ubuntu 14.04 includes the 3.13.0-24.46 Ubuntu Linux kernel which is based on the v3.13.9 upstream stable Linux kernel, which is one of the newest ones made available.

Radeon: Mesa 10.1 vs. Mesa Git On Ubuntu 14.04

Filed under
Graphics/Benchmarks
Ubuntu

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.

First Linux Kernel Update Arrives for Ubuntu 14.04 LTS, Upgrade Now

Filed under
Linux
Ubuntu

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.

Testing a new laptop with openSuSE, Fedora, Linux Mint and more

Filed under
Red Hat
SUSE
Ubuntu

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.

    Gedit is the default text editor on Ubuntu and just about a bajillion other Linux distros — but it’s also unmaintained. Did you know that? I didn’t. Not until a reader mentioned it to me earlier today. And, sure enough, head over to Gedit page on the GNOME Wiki and you can see for yourself that the project is “no longer maintained” and is “looking for new maintainers”.
  • Going to GUADEC 2017
    This year I am also giving a presentation about the application story in Endless OS. Our infrastructure, our changes to GNOME Software, our heavy use of Flatpak, etc. Hopefully you’ll find it interesting.

    I know many of you have wanted to test running Wayland on NVidia. The work on this continues between Jonas Ådahl, Adam Jackson and various developers at NVidia. It is not ready for primetime yet as we are still working on the server side glvnd piece we need for XWayland. That said with both Adam Jackson looking at this from our side and Kyle Brenneman looking at it from NVidia I am sure we will be able to hash out the remaining open questions and get that done.

  • My first year in the Fedora Project
    Yesterday I completed an incredible first year in the fedora project, I noticed it because I was awarded with one badge for it (egg badge). I arrived a month ago through whatcanidoforfedora, who told me that it was a good idea to go to ambassadors, commops and infrastructure, I tried first in ambassadors and immediately I was kicked :P. being member of any major parts of the fedora project requires a lot of patience and work. that was my first learning about the the project.
