Looks like you don't have X11 running. Most likely you forgot the -X option when connecting with ssh. Try running `xeyes` or similar to verify that you have X11 working. After that vglrun should work.

Installing VirtualGL 2.5.1 on Ubuntu 20.04 has been problematic. I have tried VirtualGL 2.6.5 as well on Ubuntu 20.04 but no luck. VirtualGL 2.5.1 install on Ubuntu 18.04 works. A reboot after running vglserver_config on Ubuntu 20.04 results in a blank screen with a blinking cursor; system comes back up on the network however - which allows me to run the vglrun command. server:opt/apps/tigervnc/1.10.1/usr/bin$ vglrun glxgears [VGL] ERROR: Could not open display :0. server:/opt/apps/tigervnc/1.10.1/usr/bin$ lsb_release -a No LSB modules are available.
