I'm running the latest desktop Ubuntu, and my system seems to have frozen -- the pointer moves when I move the mouse, but nothing else is happening; even the clock is stopped. tty1-6 work just fine, though; it's just the GUI.
Normally I'd just restart, but I have an open file in gedit with a lot of unsaved changes -- inexplicably, the auto-save hasn't worked for ages. Is there a way to go into another console, log in with the same account, and access processes in a GUI console, either to just send a "save" command or just retrieve the open file text?
ETA: I know how to get the process ID with lsof and have done so. I suspect there may be something I can do with disown or the like.
