So I upgraded my workstation from 12.04 to 12.10 and apparently broke my graphics driver in the process. I have 2 monitors connected and they were mirrored and in the wrong resolution under Gnome and XFCE4.
I tried installing the fglrx package but it errors out trying to install fglrx-amdcccle saying that it could not find the previous driver. I then tried catalyst 12.8 which failed with this error:
I thought it had to do with the older drivers not being compatible with the 3.5 kernel so I tried using the beta 12.9 but get the same error.
[Warning] Uninstall : inst_path_default or inst_path_override
does not exist in /etc/ati. This suggests that the AMD driver
is not installed, the AMD driver is only partially installed,
or the current AMD driver installed is an older version than the
one this script was designed for. Both files listed above are
required for determining where installed files are located.
To force uninstallation of the driver by guessing where the
uninstallation files are located, set the force option
re-run /usr/share/ati/fglrx-uninstall.sh (this is not recommended).
After trying to force the fglrx driver to install I was able to (somehow) get dual screens working in Gnome but not XFCE4.Things just don't seem right. For example the driver listed under System Settings -> Details -> Graphics says "Unknown".
Any help in how I could fix this would be greatly appreciated.
