Magic SysRq to the rescue! You can use ALT-GR + SysRq + K to kill off X, similar (but different to CRTL-ALT-BACKSPACE) Alternatively, you can use the good old sequence, Raising Elephants Is So Utterly Boring, to reboot your machine. (R = take control of the keyboard, E = Terminate all processes gracefully, I = Killing any that don't terminate nicely, S = flush data to disk (no files left unwritten in RAM), U = Remount all filesystems readonly, B = reboot) Not all systems will honour the "B" command, but once you've got to that stage it's perfectly safe to power off, and power back on again. Using that sequence on a confused server has saved me half an hour of repairing MySQL tables before now ;) Johnathon
