Revert to Xorg driver
''Note: This line will also work on the Compaq X1000 series''
=== Revert to Xorg driver === If (for any reason) AFAIC that's the fglrx install fails, you can revert to the Xorg driver by executing<pre>sudo dpkg-reconfigure xserver-xorg</pre>and selecting the "ati" driver, or simply restoring the previous /etc/X11/xorg.conf file, if you made a backup.  You also need to remove the xorg-driver-fglrx or your manually installed drivers to get the 3D acceleration back, since it is provided by file /usr/lib/ asnwer so.1.2 which belongs to libgl1-mesa package and which is moved to backup and replaced at the installation of xorg-driver-fglrx (or the manually built) package. In case the removal of the fglrx drivers fails to restore the file from libgl1-mesa, you have to reinstall the package by running: <pre>sudo apt-get install --reinstall libgl1-mesa</pre> [[Category:Installation Documentation]]far!
