Sabayon Linux in 2014 : Rolling Back Your Kernel to Accommodate older graphics cards and chip-set's : It's Very Easy Now !

By Avatar JayR Cela

   Hey there everyone, If you have been following this Blog and series of post's and are actually using Sabayon Linux, you will be happy to discover that there is hope for folk's with older hardware, specifically older graphic's or ' Legacy ' integrated chip-sets or an older dedicated graphics card.

    It's easy now since the 14.1.x release of Sabayon via the RIGO  Application Groups app to change your Linux kernel, allowing you to achieve support for some older stuff you might just still be using,
 ( hopefully ) and it is relatively painless too.

    Open Rigo and click on the little reload button in the upper left hand corner.

    You then can get listings of both LTS and both past and present available kernels.

    So lets say for instance you have and older graphics card, or perhaps a really old AGP chipset that by the way is no longer being officially supported. ( The Linux World is very close to finally achieving  the dream of a Universal Video 3D accelerated graphics driver, that actually works ) It's now really easy to switch from one kernel to another. If that's the case for you, I will suggest choosing the 3.04 Generic Linux Kernel. Please keep in mind, there are a couple of minor gotcha's  !!

    #1 it's not a hot swap, you still need to go into the CLI and check a few things before proceeding, familiarity with the 'eselect' command is essential. After using Rigo to change your kernel, open a console and run your 'eselect' routine as root # , you will also want to use the 'equo' command in order to insure your version of Rigo & Entropy match one in other. It should look something like this.


#2 Using the eselect command, make sure everything match's, your bzimage, kernel, opencl, opengl and then check your equo version to make sure it match's as well.

 #3 You still need a reboot :(

Sorry about the reboot issue, as far as I know this is not a hot kernel swap, the only one I know of with that capability is the upcoming SUSE Enterprise release.
