ctrl-alt-f1 terminal stuck in mirrored display mode

view story

http://askubuntu.com – I have a dual monitor setup. Lately it's been giving me grief. Today I noticed that when I "ctrl-alt-F1" to get a terminal, the terminal is mirrored display mode. Preferable would be to only see it on the primary display, of course. Within the "System Settings | Displays" I've actually got the secondary display disabled. Any idea how to fix this? Ubuntu 12.04LTS. (HowTos)
