Dear all,
First of all it's my first post here, so sorry if i'm in the wrong sub-forum or sth else. Just let me know and i'll try to correct it.
Regarding my problem:
I'm using a workstation for visualisation of some simulation data. For this we were using Ubuntu 14.04 + VNC and VirtualGL for 3D applications (gnome, xfce4 as Desktop environment). Everything was working, but after upgrading to 16.04 i just cannot get VirtualGL running properly utilizing the Nvidia Titan Z.
