is Sync, Unmount, reBoot and is the lowest-level commands you can send to the kernel when it has crashed.

There is no event defined for video-switching, but the BIOS is still trying to perform the switch.

Can you drop to a console with:

  Ctrl-Alt-F1

and then run:

  sudo tail -f /var/log/messages

whilst trying to pressing the Fn-F8 key combination. Does anything get displayed on the console?
