Sorry...no. Everything graphical running in Xorg, dies with it. Had the same here, switched to a console (Ctrl-Alt-F1 - that stil did work) and did a "reboot" as Root. Of course, doing a "pkill" adter a "ps -A" would allow the application to take action, if it could do that. A pkill is pretty ... final...
And...no, it's not a stupid question...stupid questions dont exist...
