Title:
Screen freezes after waking from suspend with Gnome on Wayland
Status in gdm package in Ubuntu:
Expired
Status in gnome-shell package in Ubuntu:
Expired
Bug description:
It appears that using Xorg instead of Wayland is the only way to fix
this problem on Ubuntu 17.10. For some odd reason, whenever I wake my
computer from suspend (especially after an extended period of time
asleep) using Gnome in a Wayland session (gnome-session and stock
ubuntu-session alike), my screen freezes completely on whatever was
last there before suspending and I can't get any IO response at all.
Nothing, the screen is totally frozen. I am also unable to exit into a
recovery shell or kill GDM or gnome-session/ubuntu-session locally. I
also can't seem to find any traces or indications for the freeze in
the syslog, or maybe I'm just not sure where to look. I believe this
is a problem with GDM on Wayland, not kernel related, as it happens on
a totally stock install and when I use an upgraded/downgraded kernel.
It literally necessitates restarting my computer. This problem is
nonexistent when using Xorg instead of Wayland with GDM. Anyone else
have this issue on Ubuntu 17.10 or figure out a solution better than
simply switching to Xorg? I should clarify that I am not using nvidia
drivers, I'm using Intel integrated graphics on a core-i7 5500U.
Ubuntu 17.10 uses gnome-session v3.26.1.
Expected behavior: When waking computer from suspend, expect GDM lock prompt
and log back in.
What happened instead: When waking computer from suspend, screen and IO is
completely frozen, necessitating a force-shutdown.
