Package: x2goserver Version: 4.0.1.19-8.fc24
When attempting to login with a client desktop session that uses dbus while logged in as the same user on the console causes an error to appear in a pop up window: Could not acquire name on session bus
You can dismiss the error but the desktop never full starts and attempts to logout triggers the logout on the console session.
From the error, I this appears to be resolved by using a custom session script in x2go and making sure to call: unset DBUS_SESSION_BUS_ADDRESS
For example: #!/bin/sh unset DBUS_SESSION_BUS_ADDRESS # redirect to /dev/null due to x2go bug 914 /usr/bin/mate-session > /dev/null
Doing some digging, it looks like the dbus socket (/usr/lib/systemd/user/dbus.socket) on fedora 24 (dbus-1.11.2-1.fc24.x86_64) does this: ExecStartPost=-/usr/bin/systemctl --user set-environment DBUS_SESSION_BUS_ADDRESS=unix:path=%t/bus
And sets the DBUS_SESSION_BUS_ADDRESS for all logins for your user.
This same workaround appears to be what tigervnc used as their permanent solution: https://github.com/TigerVNC/tigervnc/commit/c071e493a093d7ee9a568729dd2e151f...
So I think this is the proper solution.
FYI, a bug was filed against Fedora as well: https://bugzilla.redhat.com/show_bug.cgi?id=1350004
