Thank you It seems there is a permission problem. I'm not sure I'll have time to have a look at this in the next days but I'll try.
If anybody else has some clues to fix this bug, feel free to share them with us. (or maybe we should contact GNOME devs because other commands with dbus-send don't work either on a Cairo-Dock session) ** Changed in: cairo-dock (Ubuntu) Status: Incomplete => Triaged -- You received this bug notification because you are a member of Cairo- Dock Devs, which is subscribed to cairo-dock in Ubuntu. https://bugs.launchpad.net/bugs/1448418 Title: Logout not working in Cairo Dock Status in cairo-dock package in Ubuntu: Triaged Bug description: I am running cairo-dock 3.4 on a fresh clean install of Ubuntu 15.04. The logout menu in the dock does not work. That is, it does nothing if the "Logout" menu item is clicked. However, Restart and Shutdown work properly. On clicking the Logout item, nothing happens.
