Interesting update -------------------- Given the "Unit nvidia-resume.service is masked" complain by systemd- logind in my previous comment, I thought it could be related with the switching on and off the proprietary nvidia driver: after turning it on, I turned it off (switching to Nouveau) because of this other bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1947614
So, I opened the "Software & Updates" tool and in "Additional Drivers" I turned nvidia-driver-470 on again and... voila', the session-crash-on-suspend bug disappeared. It looks like to me that the tool messed up some systemd units like nvidia-resume.service and it didn't return them to the previous state after I switched back to Nouveau. Note: the only thing I used to turn on and off the nvidia driver is that "Software & Updates" tool, no custom configurations/hacks at all. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1950393 Title: GDM session crashes on suspend on Ubuntu 21.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1950393/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
