I don't think it's related to auto-login. I had this problem last week but it is not reproducible after a reboot. I attached the journal from last week.
I have the following extensions enabled: - Alternate Tab - Better volume indicator - Media player indicator - No topleft hot corner - Sound input/output device chooser - System monitor ** Attachment added: "journal.log.gz" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1799293/+attachment/5204799/+files/journal.log.gz ** Changed in: gnome-shell (Ubuntu) Status: Incomplete => Confirmed ** Changed in: gnome-shell (Ubuntu) Importance: Undecided => High ** Summary changed: - gnome session: Must ask twice to lock the screen when user has auto-login enabled + gnome session: Must ask twice to lock the screen -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1799293 Title: gnome session: Must ask twice to lock the screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1799293/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
