I need to confirm what Arthur Furlan told. I also had this problem of waiting a long long time before the quit window comes. I had also unchecked "gnome-power-manager", thinking it would be unnecessary for my desktop computer.
I tried the tip of Arthur : I re-checked the "gnome-power-manager" in the sessions' preferences to make it active and the bug is disappeared immediatly with the next login session. -- System -> Quit takes a long time to appear https://bugs.launchpad.net/bugs/123078 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
