I just finished playing xmame in full screen mode, and coming out of full screen mode messed something up. X died, and gdm was respawned.
However, interestingly, the virtual consoles 1-6 are now screwed; if I switch to them I see a mess of mostly green and black in graphics mode. Everything still works; I can log in and out there, but I can't see anything useful. What's gone wrong here, and how can I reset them without rebooting? Thanks, Neil.
