Public bug reported:
With the mapping of Super+P to video
mode(https://bugs.launchpad.net/ubuntu/+source/gnome-settings-
daemon/+bug/694910) I have unintentionally switched video modes several
times and, whilst cycling through the modes to get back to my original
setting, the system crashes, being unresponsive over a pre-existing ssh
connection, with audio playback looping over the last couple of seconds
of playback, and no reaction to keyboard input - except for holding down
the power button for several seconds.
Now I think about it, I haven't tried the sysreq magic yet - I will do
on the next one - but the crash exists, and I can reproduce by cycling
video modes with Super+p.
