Are you knowledgeable enough to log in remotely and attach a debugger to the gdm3 process when it is frozen? If so, please do and then paste the stack traces of the hung gdm3 process here.
But also... Thank you for taking the time to report this bug and helping to make Ubuntu better. Please execute the following command only once, as it will automatically gather debugging information, in a terminal: apport-collect 1728143 When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs. ** No longer affects: wayland (Ubuntu) ** Package changed: gnome-session (Ubuntu) => gnome-shell (Ubuntu) ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete ** Changed in: gdm (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to wayland 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.
