What about the Alt+SysRq method? Do these in order to try and get a working system from a lock: Alt+SysRq+K (saK = Kills all processes attached to the current vt) Alt+SysRq+E (tErm = Send SIGTERM to all processes) Alt+SysRq+I (kILL = Send SIGKILL to all processes) Alt+SysRq+S (Sync = Synchronize with disk; flush write caches) Alt+SysRq+U (Unmount = Remounts all filesystems r/o) Alt+SysRq+B (reBoot = Reboot the system) In Linux, Ctrl+Alt+Del is handled by userspace applications while Alt+SysRq+<Key> combinations are handled entirely within the kernel. Next time you are using text vt, try Alt+SysRq+/ or Alt+SysRq+<SPACE> to get a listing of Alt+SysRq commands. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
