Public bug reported: When a user logged in to the GUI session and she/he request shutdown of the system a PrepareForShutdown() signal is emitted by logind:
https://www.freedesktop.org/wiki/Software/systemd/inhibit/ Processes holding delay inhibitor locks can start their pre-shutdown operations and until they finish there is no feedback in a Unity session for the logged in user that shutdown is successfully requested on Xenial. On Bionic, the default Gnome 3 session does handle the signal and logs the user off to GDM, but GDM does not tell that shutdown is pending and the user may think that she/he can log in again or should to something to really start the shutdown. With Ubuntu's default configuration the confusion only lasted up to 5 seconds (default max delay for inhibitor locks), but the next upload of unattended-upgrades increases the delay up to 30 seconds which is more than noticeable (LP: #1803137). Please consider either logging the user off from Unity and stopping GDM to switch over the the plymouth shutdown screen of at least showing a notification about the ongoing shutdown. ** Affects: gdm3 (Ubuntu) Importance: Undecided Status: New ** Affects: unity (Ubuntu) Importance: Undecided Status: New ** Also affects: gdm3 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1803581 Title: PrepareForShutdown() is not handled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1803581/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
