If gnome-session-quit also doesn't work, then it is a bug in gnome- session, and there is nothing we can do in gnome-panel about that.
I suggest you to ping the author of the patch from bug 491940. ** Package changed: gnome-panel (Ubuntu) => gnome-session (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-panel in Ubuntu. https://bugs.launchpad.net/bugs/1326038 Title: No logout from remote flashback session in trusty Status in “gnome-session” package in Ubuntu: New Bug description: Since I upgraded our LTSP server to trusty, users cannot log out any more from the gnome session. The logout entry from the system menu and the logout button added to gnome-panel simply do nothing. Running "gnome-session-quit" from the terminal, I get the following: > ** (gnome-session-quit:2390): WARNING **: Failed to call logout: Logout interface is only available during the Running phase The only way to end the session is "killall -u $USER". Note that the X session is running remote (LTSP thin client). Same problem when running via XDMCP.
