Public bug reported: I've written an AskUbuntu question about this: https://askubuntu.com/questions/1511958/screen-lock-keeps-occuring- on-24-04-even-though-i-believe-ive-disabled-it/1512075#1512075
Originally I thought it was gnome not respecting my setting to prevent locking the screen after idling, but after discussing the issue on matrix (https://matrix.to/#/!EJhpCQHHqqcNicfiql:xentonix.net/$kPbn- fqDZgoG4s6PyQfki8tcSKJUpGH9QrXZSSV_vKY?via=decred.org&via=matrix.org&via=ubuntu.com) I think it is actually just a gdm or gnome-shell crash that happens when the PC idles, the screen turns off, and then I wake it. To summarize the symptom. I have the PC set to disable the screen after being idle for 5 minutes. I also set it such that it should not lock the session when this happens. (I want to turn on the screen and get right back to where I was without password overhead). What I've observed is that when I give the idle PC keyboard input, it wakes to a login screen, and when I login my windows from the previous session are completely gone (although tmux sessions are still alive). I've attached a relevant section of `journalctl --user` from around the time when I last tried to interact with the idle PC. I believe the "wake" event happens at `Apr 28 13:42:43` at which point we start seeing whoopsie messages: ``` Apr 28 13:42:44 toothbrush systemd[1]: Started whoopsie.service - crash report submission. ``` And then what looks like logs indicating that I was logged out and the previous session was ended: ``` Apr 28 13:42:56 toothbrush systemd[1]: run-user-1000-gvfs.mount: Deactivated successfully. Apr 28 13:42:57 toothbrush gdm-password][60731]: pam_unix(gdm-password:session): session closed for user joncrall Apr 28 13:42:57 toothbrush systemd[1]: session-61.scope: Deactivated successfully. Apr 28 13:42:57 toothbrush systemd[1]: session-61.scope: Consumed 12min 9.467s CPU time. Apr 28 13:42:57 toothbrush systemd-logind[1790]: Session 61 logged out. Waiting for processes to exit. Apr 28 13:42:57 toothbrush systemd-logind[1790]: Removed session 61. ``` The time from `13:42:44` to `13:43:07` where I get: ``` Apr 28 13:43:07 toothbrush systemd-logind[1790]: New session 221 of user joncrall. Apr 28 13:43:07 toothbrush systemd[1]: Started session-221.scope - Session 221 of User joncrall. ``` seems about right, because it takes a few seconds to go from de-idling the machine to seeing any sort of display.
