Recovering from stuck graphics

• If your graphical session is stuck and you can no longer type in your terminals, don't reboot!

• It is very likely that your system is still fine. Try to access a text console by pressing the [Ctrl][Alt][F1] keys (or [F2],[F3] for more text consoles)

• In the text console, you can try to kill the guilty application.

• Once this is done, you can go back to the graphic session by pressing [Ctrl][Alt][F5] or [Ctrl][Alt][F7] (depending on your distribution)

• If you can't identify the stuck program, you can also kill all your processes: kill -9 -1 You are then brought back to the login screen.
