Hi Experts,
I recently upgraded my server from SLES 11 SP3 to SLES 12 SP1. I used to have Xvnc setup before and worked OK for multiple session logins
After upgrade, I am able to only connect with one instance of VNC per user. Second session fails due to GNOME issues
Below is what I can see from the syslog

===========
With my limited knowledge on the SUSE/GNOME, Looks like the gnome is unable to spawn a another instance ?
I could find lot of threads describing what to be done to fix the issue related to “WARNING: Failed to acquire org.gnome.SessionManager”. However none of them work on my server. Here are the rpm list currently installed on my server.
