I suggest that you attach the last several Xorg.n.log's from /var/log in order to look for why the X server would have crashed.

It does not matter what applications are running - sometimes I get it when I have only the browser running, sometimes during playing a video and sometimes when doing something in Eclipse. It started about 2-3 weeks ago. The only trace in the logs I was able to find is: [+1980.37s] DEBUG: Process 1391 exited with return value 1 [+1980.37s] DEBUG: X server stopped [+1980.37s] DEBUG: Removing X server authority /var/run/lightdm/root/:0 [+1980.37s] DEBUG: Releasing VT 7 [+1980.37s] DEBUG: Display server stopped [+1980.37s] DEBUG: Stopping display [+1980.37s] DEBUG: Session 2068: Sending SIGTERM [+1980.49s] DEBUG: Session 2068 exited with return value 0 [+1980.49s] DEBUG: User session quit [+1980.49s] DEBUG: Display stopped [+1980.49s] DEBUG: Active display stopped, switching to greeter [+1980.49s] DEBUG: Switching to greeter [+1980.49s] DEBUG: Starting new display for greeter [+1980.49s] DEBUG: Starting local X display [+1980.49s] DEBUG: Using VT 7 [+1980.49s] DEBUG: Logging to /var/log/lightdm/x-0.log [+1980.49s] DEBUG: Writing X server authority to /var/run/lightdm/root/:0 [+1980.49s] DEBUG: Launching X Server [+1980.49s] DEBUG: Launching process 7495: /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch [+1980.49s] DEBUG: Waiting for ready signal from X server :0 [+1980.78s] DEBUG: Got signal 10 from process 7495 [+1980.78s] DEBUG: Got signal from X server :0 [+1980.78s] DEBUG: Connecting to XServer :0 [+1980.78s] DEBUG: Starting greeter Unfortunately I was not able what was process 1391 in that case. Maybe the attached logs will help you discover it. I am able to reproduce it so if you need any additional logs I should be able to get them right after the next crash.
