Hi,

I had a Linux partition set up on my X5000 and was working OK. However, a few weeks ago I ran a software update and after rebooting, now I only get a screen of grey garbage.

As there any means to fix this, or will I need to reinstall from scratch?

Which kernel and which Linux distribution do you use?

Which graphics card do you have? I experienced exactly the same with my R7 240 (Oland chip set), after I had updated Ubuntu 16.04! Last night I found a solution... I edited the "/etc/X11/xorg.conf" and "/etc/X11/xorg.conf.cyrus" files (have not yet tested which of them is really used in booting) and changed the line

Driver "radeon"

to

Driver "fbdev"

After that, my Ubuntu 16.04 booted again normally with R7 240. (A HD 5450 worked ok also without this change).

But what is peculiar, Mate Remix 2017, which is basically Ubuntu 17.04, does not work with my R7 240 even though there is 'fbdev' in the xorg.conf, or even if I replace the whole X11 directory with that of 16.04...

@Roland ,

There is an issue with the Mesa version on Mate Remix 2017 .
See the instructions linked below for making it work by replacing the Mesa .
You may have to use your Radon HD 5450 to do this .

I'm not sure. It's the one you posted here: http://forum.hyperion-entertainment.biz ... =58&t=3577

My graphics card is a Radeon HD7850 Pitcairn Pro.

The problem is caused by an upgrade to Mesa.
It will not boot with a Radeon HD Southern Island card unless the /etc/X11/xorg.conf device section is changed from radeon to fbdev.
you can boot the original installer (which has been updated with the fbdev) and use it to replace your hard drive installation's /etc/X11/xorg.conf file.
You can copy it for the same location on the installer /etc/X11/xorg.conf or download from here :
https://drive.google.com/open?id=0BxoZd ... FdWRkFZSU0
copy it to /etc/X11/xorg.conf .

Or if you opt to do a new installation download the installer again as it has been updated to prevent the problem happening .

Thanks, much obliged, back to normal.

Do you have any tutorials on doing really, really, really basic stuff like changing the kernel? There's so much I have no idea how to accomplish.
