Please explain in more detail what you see after locking once vs twice. Also note existing bug reports: "dock is visible when screen is locked" -> bug 1769383 "once screen is unlocked the dock disappears even after pressing activities" -> bug 1796265, bug 1801494
Finally, please try disabling all gnome-shell extensions and see if that fixes things. ** Changed in: gdm3 (Ubuntu) Status: New => Incomplete ** Also affects: gnome-shell (Ubuntu) Importance: Undecided Status: New ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1803807 Title: Lock screen doesn't work in 18.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1803807/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
