In my continued research on this problem, I have found two very similar if not the same bug in #46557 and #48318. One of which indicated using "AlwaysRestartServer=true" for GDM in /etc/gdm/gdm.conf. Ubuntu gdm.conf recommends entry in /etc/gdm/gdm.conf-custom which over-rides gdm.conf. That didn't work for me.
I will continue to use an older version of xorg-driver-fglrx until this gets fixed. I hope it's soon. -- Lockup problems with both the free xorg ATI driver and the proprietary fglrx driver, using various ATI cards https://launchpad.net/bugs/30447 -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
