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 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
