[Bug 1950393] Re: GDM session crashes on suspend on Ubuntu 21.10
Hi Daniel, In my understanding, the crash is not reproducible after my workaround (switching to the nvidia driver), because the nvidia-resume.service is not masked (my theory). Therefore, I switched back to the Nouveau driver, and I reproduced the problem and collected the system logs as you asked. Now prevboot.txt contains the logs from a clean boot, through the session crash and ends with a (user requested) reboot. Just for the record, these are the steps to reproduce the bug: 1. Install Ubuntu 21.10 on a laptop(?) with an nvidia GPU 2. Open "Software & Updates" -> "Additional Drivers" 3. Select the latest driver (470) 4. Reboot 5. Login normally on GDM 6. Open "Software & Updates" -> "Additional Drivers" 7. Select "Nouveau display driver" and apply the changes 8. Reboot 9. Login normally on GDM 10. Try to suspend the system 11. You should observe a session crash here ** Attachment added: "System journal for the previous boot, as requested in update #8" https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1950393/+attachment/5540130/+files/prevboot.txt -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in 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 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

If the crash returns then please: 1. Wait 10 seconds. 2. Reboot. 3. Run: journalctl -b-1 > prevboot.txt 4.

[Bug 1950393] Re: GDM session crashes on suspend on Ubuntu 21.10
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 Desktop Bugs, which is subscribed to gdm3 in 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 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Hi Daniel, unfortunately, there are no crash files in /var/crash/. I've checked also: https://errors.ubuntu.com/user/ but there are no crashes reported in the last month. It looks like the "crash" is not caused by a fatal signal like SIGSEGV and no core dump is generated. But, still from the same log file (attached), I noticed that systemd- logind exited with a failure: -- Nov 10 00:20:13 lenovo upowerd[3602]: Could not acquire inhibitor lock: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying Nov 10 00:20:13 lenovo dbus-daemon[1120]: [system] Activating via systemd: service name='org.freedesktop.login1' unit='dbus-org.freedesktop.login1.service' requested by ':1.178' (uid=1000 pid=12386 comm="/usr/lib/xorg/Xorg vt2 -displayfd 3 -auth /run/use" label="unconfined") Nov 10 00:20:13 lenovo gsd-power[12749]: Unable to inhibit suspend: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying Nov 10 00:20:13 lenovo gsd-media-keys[12746]: Unable to inhibit suspend: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying Nov 10 00:20:13 lenovo systemd[1]: Starting SSSD PAM Service responder...

Thanks for the bug report. Your log shows evidence of bug 1949352 but that probably doesn't explain "session crashes". The most common GDM crash we are seeing in 21.10 is bug 1945061.
