When using fglrx, screen turns to garbage once mythfrontend starts - fine beforehand
I am re-asking this question here under the correct title, as the discussion has been in https:/
I tried switching to the non-free drivers through the "Restricted Drivers Manager". Now I just get coloured dots and shapes instead of a desktop etc. X seems pretty stuffed on both D-Sub and HDMI.
What is the easiest

I think you might have a driver conflict if you are having these results. I
suggest checking to make sure you are actually using the correct drivers
# sudo dpkg -l | grep xorg-driver-fglrx
If you get nothing back fglrx is not installed. If it does come back with
the package info, try the following:
# sudo dpkg -l | grep ati
There should not be any ati packages other than the Ati Catalyst Control
Centre. If there are packages driver packages installed, do this:
# sudo dpkg --purge <package_name>
Then edit your xorg.conf and make sure in the device section:
Driver "fglrx"
Then restart gdm:
# sudo /etc/init.d/gdm restart
If its still not working try a reboot just for good measure.
-Nick
# sudo apt-get install --reinstall xorg-driver-fglrx

Thank you very much for your help, Nick.
That didn't fix my problem. There was a xserver-
I watched more carefully this time, and the desktop comes up okay, but as soon as Mythfrontend starts, the screen goes crazy - it is like some of the pixels (only some, most of the screen is black) from a band down the left side have been stretched across the whole screen. For example, if I move to the second virtual desktop (Ctrl + Alt + Right) and click in the top left corner, a group of white dots drops down (the applications menu) across the full width of the screen.
Any further help would be excellent. If we can't sort out Fglrx, is there an easy way to go back to the stock ati driver short of reinstalling?
Is the non-free driver likely to improve performance even though no video formats are specifically accelerated (no UVD support etc.)?

I've changed back to ati by doing a sudo apt-get -f install and then changing the xorg.conf to read "ati" in the device section.

Nick, I found this, which sounds like it could be my problem:

do you think that is likely to be it? How do I best:
Insert the following into a startup script so that it is run before mythfrontend:
export LIBGL_ALWAYS_
Thanks in advance!
