Within about 2 minutes gdm/Xorg hard crashed, the screen was black, and the system was unresponsive to the usual keyboard entries (i.e., ctrl-alt-F2, ctrl-alt-bksp, ctrl-alt-delete). I did not get the "gdm Ooops something has gone wrong" screen. I had to hard power reset the system. On rebooting, I see this in /var/log/messages.
