I am facing the exact same thing with a fresh install of 17.10 on my XPS 13 9343. The occurrence seems absolutely random, but it feels like the occurrence becomes more often over the time.
I will now switch to Xorg for both GDM and the session itself. I report back after some days. For me, while the issue occurs I can still toggle the keyboard back light and the wireless kill switch. The network seems fully responsive, but as I logged in using SSH, I was not able to find any log messages or strange system behavior. -- Greetings from 34c3 (just writing this in case anyone wants to meet for debugging :-)) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gdm in Ubuntu. https://bugs.launchpad.net/bugs/1728143 Title: Screen freezes after waking from suspend with Gnome on Wayland Status in gdm package in Ubuntu: Incomplete Status in gnome-shell package in Ubuntu: Incomplete 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.
