Fix Logout issue on Dell D600 on Ubuntu

Was having an issue with Edgy Eft on a Dell D600 using a compiled version of the FGLRX driver (version 28.8), Radeon Mobility 9000. When logging out, I would be greeted with a blank screen. The following fixed the issue:

$ sudo vi /etc/X11/gdm/gdm.conf

then scroll down end edit/add the following line:

AlwaysRestartServer=true
