The shutdown is caused by the commit of https://bugzilla.gnome.org/show_bug.cgi?id=688076.
gnome-session-bin handle the first shutdown request, and change to QUERY_END_SESSION_PHASE, but the second shutdown request arrive before it open the endSessionDialog, and user not yet confirm to shutdown. The second shutdown request is handled in QUERY_END_SESSION_PHASE, which goes to prepare shutdown by the commit mentioned above. Therefore, I create a patch to check if the shutdown has been confirmed by the user then process the prepare shutdown. It seems can fix this issue. ** Bug watch added: bugzilla.gnome.org/ #688076 https://bugzilla.gnome.org/show_bug.cgi?id=688076 ** Patch added: "Patch which verified OK on the platform has 2 key event with single press" https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/1878351/+attachment/5381991/+files/check-if-logout-forced-before-perform-shutdown.patch -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/1878351 Title: System shutdown directly by pressing power button and releasing immediately on Dell Vostro 5301 Status in OEM Priority Project: Confirmed Status in gnome-session package in Ubuntu: New Status in linux package in Ubuntu: Confirmed Bug description: kchsieh@kchsieh-laptop:~$ lsb_release -rd Description: Ubuntu 20.04 LTS (fossa-bulbasaur X23) Release: 20.04 kchsieh@kchsieh-laptop:~$ apt-cache policy systemd systemd: Installed: 245.4-4ubuntu3 Candidate: 245.4-4ubuntu3 Version table: *** 245.4-4ubuntu3 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status Expect: When press the button, the endSeesionDialog should show up.
