I also note that something similar used to happen in Hardy, though I can't recall whether the cursor would flash or not. Note that this doesn't happen every time either, usually only maybe after a few days to a couple weeks. But like one of the other people people here have said, the user will be switched from myself to my wife multiple times per day. So in almost every case, this bug only surfaces after quite a few user switches.

The user switching to is not logged in yet. Expected behavior: Click current user up top> from the drop-down click the user wanting to log in > brought to the lightdm log in screen and log that user in Instead: Click current user up top> from the dropdown click the user wanting to log in > brought to a black screen with a blinking cursor From here, you cannot type or initiate any keyboard shortcuts other than Ctrl +Alt+F(1-6) to reach tty1 etc, or Ctrl+Alt+F7 to return to the user that you were originally trying to switch from. Ctrl+Alt+F8 will bring you back to the black screen. This happens pretty often so I should be able to test anything needed. Thanks!
