Title:
gnome-shell freezes after resume then unlock
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
Often after resuming and then entering my password to unlock gnome-
shell, when I press the enter key gnome-shell immediately freezes. The
lock screen is still displayed, the mouse no longer responds, and the
keys no longer respond (I can't even get a tty console with CTRL-ALT-
Fn key). I have to perform a hard reset at this point because gnome-
shell remains frozen even after leaving the PC alone for 15 minutes.
I haven't been able to find any crash files or error logs.
It seems that this freeze is much more likely to occur if I have
changed location between suspending and resuming and am therefore
connecting to a different wifi router. Once, however, it happened at
home on the same router and I was able to log in via ssh from another
machine (so only gnome-shell was frozen, not the kernel). However, I
couldn't see any messages or reason that gnome-shell had crashed, so
all I could do was reboot (any hints as to what I should try at this
stage are welcome).
Bug #1709994 looks similar but in that case a) the user is using Xorg,
not Wayland, b) he also gets past the lock screen, and c) gnome-shell
eventually restarts.
