Public bug reported:

Frequent crashes when I;
* unlock the screen
* resume from suspend

Usually, I see the login page, I put my password and then it's 50:50
chance that it will crash. If it crashes, there's a brief flash in
screen and then it goes black. I cannot fire up tty with ctrl+alt+[1-7].
I had to reboot in that case (I use SysRq Magic+R,E,I,S,U,B)

If it does not crash, then I can login to system, I can see the desktop
but it stays unresponsive for 10-30 seconds and then gnome-shell
restarts, and then I can start using the windows/programs.

Not sure if this is Xorg or gnome-shell or gdm3 problem.
