Hello, I think that I found a solution... I tested (and retested) and it works for me. To discover what's the problem that was causing the longer time I executed
$ tail -f ~/.xsession-errors and then I executed $ gnome-session-save --kil that is the same command that runs when you click on "Session > Quit" button. After some time I got the following message ** (x-session-manager:7532): WARNING **: Couldn't connect to PowerManager Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. It occurs for me because I disabled the gnome-power-manager of session startup (I have a desktop, so it's unecessary). To solve the bug I opened the "System > Preferences > Sessions" and added the gnome-power-manager as a startup program. Anybody can confirm if it really solves the problem? -- 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
