Sebastion's comment led me to test my commonly used applications to see if one was responsible for this issue. I found that the issue always occurs if I have Krusader open (i.e. computer shuts down immediately). And yes, Krusader does use qt. If I close Krusader before triggering the command "gnome-session-quit --power-off", then the dialog box appears as it should normally. It seems reasonable to mark this bug as a duplicate of bug #1426851. ** This bug has been marked a duplicate of bug 1426851 Power button shuts down computer if a Qt application is running -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1505070 Title: gnome-session-quit --power-off produces immediate shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/1505070/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
