It might be the systemd OOM killer. You can see the journalctl output for your current boot with "journalctl -b 0", the previous boot with "journalctl -b -1", etc. Get the output for whichever boot the logout happened in and grep for the word "pressure". I had a similar problem with non-DE logins ( https://bugzilla.redhat.com/show_bug.cgi?id=2177722 ) but that was fixed with recent systemd updates. When it happened to me I saw a line like "Killed /user.slice/user-0.slice/session-1.scope due to memory pressure for /user.slice/user-0.slice being 67.40% > 50.00% for > 30s with reclaim activity". _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
