Q:

How to enable ctrl-alt-backspace using console?

How do I enable ctrl-alt-backspace using console? I have problems with X.org and often server gets stuck with black screen. I'm trying to solve this issue, but I can't find a way to kill X. ctrl-alt-F(n) does not switch to a terminal.

A:

Ctrl+Alt+Backspace is deprecated, use the Magic SysRq Key for restarting X instead, which is Alt+Print+K.
Alternately, if you can switch to the tty consoles, you could try to use sudo killall X for killing off X.
Sidenote: Be aware that the killall command kills all processes with the given name only under Linux. Under BSD f.e., it will kill all processes...which is a rather bad thing to do.
