Public bug reported:
Sometimes, while using my computer, everything on the screen just
freezes (but audio keeps playing) and then a couple seconds later,
everything is black (and audio stops at this point), and then I am
brought back to the login screen. In addition, the numlock light on my
keyboard is lit up, but numlock is actually turned off, requiring me to
hit the numlock key again. I don't know if using two HDMI monitors at
once is relevant or not.
