Public bug reported: This started about a week ago, I started getting very frequent problems with lockscreen and switching users. After using either of them never brings the system back. Most of the time I just get a black screen (sometimes with mouse cursor).
The system seems to respond to keyboard but the display is broken. I have no clue whether it's xorg, lightdm or anything else. This never happened until a few days ago.
