Re: What should be done when Ubuntu crashed?
There's a bunch of stuff I usually do when Ubuntu(or just Xorg) crashes. First I try to access the command line with ctrl+alt+F2 or whatever F-key different than F7 since that's the one you just crashed. If I manage to access it, I usually see command
to see if any process takes 100% of CPU, and then kill it. Otherwise, I run command
to restart Xorg and go back to login screen.
sudo /etc/init.d/gdm restart
If I fail to access the command line, I try ctrl+alt+backspace, and as this usually fails too, I open up my second PC and try to access my ubuntu box via ssh. From there, I can restart my xorg with the command above. If this fails, then there's not much to do but a hard-reset. Sometimes I just push the powerbutton once and ubuntu starts the normal shutdown-process.
