Hi, I also saw the other e-mail exchange with Brian where you concluded to purge all "fglrx"-related packages. Similarily, there seem to be "nvidia" packages on your system. Try
dpkg -l | grep -i nvidia Purge them also. Then have a look which xorg-video drivers are left: dpkg -l | grep xorg-video Leave only xserver-xorg-video-radeon on the system. And have a look if there's still an "glx-alternative" package left, like glx-alternative-mesa. This could also be purged. Regards, jvp.
