Public bug reported:
I close the laptop lid and let it suspend. On resume, the whole desktop
is frozen for a while. Nothing works during this time, no CAPS LOCK
indicator LED, neither TTY switching. Then the screen goes dark and I
see the LightDM login screen. I was logged out.
This is a regression, since it wasn't reproducible on Ubuntu 19.04.
How reproducible?
100% of the time.
I am not totally sure it was LightDM's fault. It is my best guess based
on the behavior I witnessed.
See logs.
