Trouble with mate-session, "Could not make bus activated clients aware..."

[qwofford]

Hello,

Note: Server is Centos 7.

I've been starting my Xvnc server as a non-privileged user in the following way: "TVNC_WM=mate-session /opt/TurboVNC/bin/vncserver". For a while, this was enough to allow me to connect via TurboVNC Viewer. Recently however, when I connect to this server, I have been getting an error from the VNC Viewer GUI:

"Could not connect to session bus: Failed to connect to socket /tmp/dbus-<unique string>: Connection refused"

Followed by another popup in TurboVNC Viewer:

"Could not acquire name on session bus"

I don't see any errors in the appropriate ~/.vnc/*.log files, I do see errors in /var/log/messages:

When I start the VNC server in the same way as root, I'm able to start a mate session and work with a desktop.

Additional relevant logs from ~/.vnc/*.log, not sure how I missed these before:

Please disregard! Anaconda had taken over some dbus libraries. Removing anaconda from my PATH resolved the issue.

Glad to hear. My favorite problems are the ones that solve themselves. :)
