This same thing has happened to me more than once. I was just trying to open OpenOffice and my X session stopped. I was left with a login screen. As you can imagine, this is very annoying.
When I logged back in, I was left with the following in /var/log/syslog: Sep 17 13:45:55 linux13 gdm[4043]: WARNING: gdm_slave_xioerror_handler: Fatal X error - Restarting :0 Sep 17 13:45:55 linux13 kernel: [2342653.228830] pidgin[15703]: segfault at 9728000 ip b7da5253 sp bff87300 error 6 in libX11.so.6.2.0[b7d76000+ea000] -- segv in xserver with xserver-xorg-video-radeon https://bugs.launchpad.net/bugs/367567 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
