[VGL] ERROR: Could not open display :0.
Do note that for VirtualGL has to connect :0 to access the 3D Graphic Card. Apparently, VGL cannot get access to the display :0
Possible resolution 1:
Is the X Server up? X Server should be up to allow connection to display :0
Possible resolution 2:
Granting access the 3D X Server Read Granting Access to the 3D X Server from VirtualGL Documentation
Possible resolution 3:
After configuring access to the 3D X Server and booting to init 5, you should log off completely and log in for the VirtualGL test. I did not log-off and was wondering why I have the above error.
There may be other resolutions.....Will document when it comes along
