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.
I'll have to print this out. I used to use a couple of them, but did not know most of them. I still would have been surprised if they worked (I tried a lot of other things), but they are certainly worth a try if it happens again.
