Ah yes, the "magic keys." Holding down Alt and SysRq (which is the Print Screen key) while slowly typing REISUB will get you safely restarted. REISUO will do a shutdown rather than a restart. I don't know about Debian (because currently not installed), but in Ubuntu this useful feature is disabled by default. It can be turned on easily enough. As root open file /etc/sysctl.d/10-magic-sysrq.conf and comment out or modify the line that says: kernel.sysrq = 176 (note: might not be "176") and change it to: kernel.sysrq = 1 Reboot, and you're done. Another ctrl-alt combination that's disabled in Ubuntu is the ability of ctrl-alt-backspace to break out of X and take you to the login prompt. You can enable it by adding the following line to .bashrc and .bash_profile: /usr/bin/setxkbmap -option terminate:ctrl_alt_bksp cheers, Robert
