Alt-SysReq-K after Unity crash causes LVDS to fade into funky colors and force a restart

Binary package hint: unity

This is something I've experienced with Compiz in the past, but this happens reliably with Unity.

Restart is the only option unless you have an open, focused Nautilus window and restart Unity manually with /usr/bin/unity or /usr/bin/compiz.

I'll attach a photo the next it happens.
