Those messages are a result of Xorg crashing - i.e. various X11 apps 
complaining that Xorg has gone away ...

Any Xorg crash details will be in /var/log/Xorg.?.log - however, if Xorg 
has restarted since the crash, then the error should be in 
/var/log/Xorg.?.log.old

The error may also be in one of the log files in /var/log/gdm/
