Public bug reported:
I am on a Dell Precision 5520 running 18.10 with default settings,
nvidia drivers, and updated this morning. The bug started yesterday or
the day before.
I have the laptop set to suspend on lid close. Since yesterday, when I
open the lid and the display comes back on, the lock screen doesn't
display. I see the dock bar on the left, the menu at the top, and either
all black or whatever I was working on in the middle. I can move the
mouse, but cannot interact with anything in the dock or the main
display. I CAN interact with the power dropdown at the top right, where
I can select a "pause" logo- which will cause the power to go off (fully
suspending the machine presumably)... and from there when I wake it back
up, the lock screen is properly displayed. I have ALSO tried mashing
function keys to restart the GUI, and a couple times some combination of
alt-ctrl-shift and some function keys have gotten me to a working login
screen (and after typing my password, back to my working session) but it
hasn't worked that way when trying to do it scientifically and press the
buttons slowly to figure out which ones caused it.
