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:

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:

So I think this is the proper solution.

FYI, a bug was filed against Fedora as well:
