1. Look in /var/crash for crash files There are files in /var/crash but dated June 15 2021, one from _usr_lib_slack_slack and one from _opt_google_chrome_chrome. Nothing from 21 June (yesterday) when the issue last happened.
2. If step 1 failed then look at https://errors.ubuntu.com/user/ID There is nothing recent reported on that page. The most recent reports correspond to the Slack (https://errors.ubuntu.com/oops/0b7133f8-cdfb-11eb-9cf8-fa163ee63de6) and Chrome (https://errors.ubuntu.com/oops/1277eade-cdfb-11eb-a58b-fa163e983629) issues from June 15. There is an older gnome-shell error dated 2021-05-21 16:05 with this link: https://errors.ubuntu.com/oops/3373e2ec-ba4b- 11eb-9041-fa163e102db1 and also an even earlier gnome-shell error dated 2021-03-23 14:03 with this link https://errors.ubuntu.com/oops/0bcaf4d6-8be6-11eb-93be-fa163e6cac46 3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1. I have applied that work around and will follow that advice. * Next time the problem happens, wait 10 seconds, reboot and then run: The next time the issue happens i will attach the output from journalctl. * Check the 'Extensions' app to ensure you don't have any extensions other than the three Ubuntu extensions The only three extensions reported are "Desktop Icons", "Ubuntu AppIndicators", and "Ubuntu Dock" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1933118 Title: Screen freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1933118/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
