I checked that page, but the issue it describes did not seem to be present. Using the information from it, however, I removed and reinstalled the fglrx packages (it said they contain the hacks necessary to ensure this is all correct). This made no difference.

I found this page describing the exact issue on Ubuntu. As per its suggestion, I downloaded the latest driver from ATI and tried to install. I attempted to make a deb, but the script failed on this (cp unable to stat /usr/X11R6/modules/linux error). I then just used the non-distro-specific install. This has allowed me to load X again, but things do not seem to be quite right.

If I attempt to verify the install worked:

Code:

$ fglrxinfo 
X Error of failed request:  BadRequest (invalid request code or no such operation)
  Major opcode of failed request:  144 (GLX)
  Minor opcode of failed request:  19 (X_GLXQueryServerString)
  Serial number of failed request:  10
  Current serial number in output stream:  10

On the other hand, `ldd /usr/bin/fglrxinfo' seems to look correct. My window manager (pekwm) is now behaving *very* slowly when I move windows, and I cannot seem to play videos (mplayer). Well, I can play them and the audio stream works, but there is no video stream. Otherwise, X seems normal now (I am able to post this direct from my PC with Iceweasel).

EDIT:
Oh, I almost forgot. I tried to use `module-assistant a-i fglrx' too, but there is an error here too (which seems to be a known bug).
