Public bug reported: 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. ** Affects: gdm (Ubuntu) Importance: Undecided Status: New ** Affects: gnome-session (Ubuntu) Importance: Undecided Status: New ** Affects: wayland (Ubuntu) Importance: Undecided Status: New ** Tags: gdm gnome-17.10 gnome-session suspend-resume ** Also affects: gnome-session (Ubuntu) Importance: Undecided Status: New ** Also affects: wayland (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to wayland in Ubuntu. https://bugs.launchpad.net/bugs/1728143 Title: Screen freezes after waking from suspend with Gnome on Wayland To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/1728143/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
