Kicking Linux's Tires

Test-Drive From a CD

In times past, the only way to see if Linux would work on a given PC was to install the OS. Times change. These days there are many so-called Live CD versions of Linux that boot and run from a CD-ROM.

Now, here comes the question that's arrived in my inbox so many times, I'm embarrassed for not having spelled out the answer before.

Question: "How do I download a stinkin' CD?"

Answer: Linux Live CDs and installation CDs are often made available for download as files with an .iso extension. These files are a snapshot image of a CD-ROM's file system. You grab the ISO file, feed it to your CD-burning software of choice, and a few minutes later you've got a shiny disc that will actually do something cool.

Set Up a Dual-Boot System

If you like what you see, or you wanna see the real deal, why not set up your machine to dual boot? At power-up, you'll get to choose between Windows or Linux. On the Linux side, you'll have the increased performance of a true installation (as opposed to running from a CD), the ability to install additional software, a home directory to call your own, and so forth.

Partioning the Drive

Most Linux installers default to using two partitions: one for the operating system and all user data, and one for the swap partition. (A swap partition is akin to Windows' swap file; Linux just happens to use a separate partition for virtual memory.) But there's a better way: Create one partition for the operating system, one for user data, and one for swap space. This way, if you ever need to reinstall Linux, you don't lose all your files and settings: You can tell the installer to format the OS partition, but leave others alone. In this fashion, you're far more protected from unintentional system hosings if you're the type to get under the hood and tinker around with your new OS. Your worst-case scenario is a reinstall that won't kill off your data.

Ubuntu 16.04.2 LTS Delayed Until February 2, Will Bring Linux 4.8, Newer Mesa

If you've been waiting to upgrade your Ubuntu 16.04 LTS (Xenial Xerus) operating system to the 16.04.2 point release, which should have hit the streets a couple of days ago, you'll have to wait until February 2. We hate to give you guys bad news, but Canonical's engineers are still working hard these days to port all the goodies from the Ubuntu 16.10 (Yakkety Yak) repositories to Ubuntu 16.04 LTS, which is a long-term supported version, until 2019. These include the Linux 4.8 kernel packages and an updated graphics stack based on a newer X.Org Server version and Mesa 3D Graphics Library. Read more

Calamares Release and Adoption

  • Calamares 3.0 Universal Linux Installer Released, Drops Support for KPMcore 2
    Calamares, the open-source distribution-independent system installer, which is used by many GNU/Linux distributions, including the popular KaOS, Netrunner, Chakra GNU/Linux, and recently KDE Neon, was updated today to version 3.0. Calamares 3.0 is a major milestone, ending the support for the 2.4 series, which recently received its last maintenance update, versioned 2.4.6, bringing numerous improvements, countless bug fixes, and some long-anticipated features, including a brand-new PythonQt-based module interface.
  • Due to Popular Request, KDE Neon Is Adopting the Calamares Graphical Installer
    KDE Neon maintainer Jonathan Riddell is announcing today the immediate availability of the popular Calamares distribution-independent Linux installer framework on the Developer Unstable Edition of KDE Neon. It would appear that many KDE Neon users have voted for Calamares to become the default graphical installer system used for installing the Linux-based operating system on their personal computers. Indeed, Calamares is a popular installer framework that's being successfully used by many distros, including Chakra, Netrunner, and KaOS.
