The third command line given in post #4
dbus-send --session --type=method_call --print-reply
--dest=org.gnome.SessionManager /org/gnome/SessionManager
org.gnome.SessionManager.Logout uint32:1
actually DOES WORK if no other method has been used since login (the
other two lines from post #4 or log out menu). It immedeately logs out,
no dialog is presented.
I've tested the behaviour on my laptop (Thinkpad X61 Tablet) with an
installed up-to-date Ubuntu Gnome 16.04, Ubuntu Gnome live cd 16.04.1,
and Ubuntu live cd 16.04.1. In addition I've tested this on another,
more modern computer (i5 etc.) with the live cd:s. It works always,
unless one of the other methods is used first. In that case it behaves
just as in the earlier posts.
For live cd:s I installed packages cairo-dock, compiz, and unity-
settings-daemon. Ubuntu cd needed adding universe to sources.list to
find cairo-dock. Then I created a new test user, logged out from the
current session, and logged in with the test user. I tried the
different command lines and log out menu, and if failed, forced logout
('killall gdm-x-session' or 'killall -9 gnome-session-binary') and tried
again.
First and second command lines in post #4 seem to do something, as first
run of either of these after login completes without error, though it
does not actually log out.
Unfortunately it seems that currently editing log out applet settings to add a
custom command line for logout does nothing, so no clean workaround there.
(Command line for shutdown command doesn't work either, but switch user does.)
Hope this helps :)
