Public bug reported:
First, let me provide necessary information about system or packages
System: Ubuntu 18.04.1 LTS
Package version: gnome-shell 3.28.3-0ubuntu0.18.04.2
The problem started 3-4 weeks ago (probably after updating several
packages via `apt update; apt upgrade`
After *almost all* screen unlock or resume from sleep events, this is what
happens:
* I briefly see the desktop screen (which is security or privacy problem I
guess)
* then login screen comes up, asking for the password
* after I put the password there is a wait (5-10 seconds)
* after that there are two possibilities:
1. there's brief flash in screen and then screen goes black. i can not fire
up tty consoles and i have to use SysRq Magic keys to reboot the system
2. if it does not crash, I login the system, I see the programs/windows but
they're unresponsive for 10-30 seconds. after unresponsive time, gnome-shell
restarts and only then system starts to function normally. Then apport-bug is
started for gnome-shell, I try to send the crash reports.
I'm not sure this is gnome-shell or gdm3 or Xorg problem. But, apport-
crash always starts collecting data about gnome-shell, thus I filed
report against gnome-shell. I also filed bug report against xorg
(https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1797124).
Let me provide additional info that might help;
- I have nvidia drivers installed in system
- gnome-shell produces tons of journal entries (this apport-crash reports are
huge, nearly 150 MB and I cannot upload them)
