You should definitely use VirtualGL 2.6.5, since Ubuntu 20.04 is not
supported with VirtualGL 2.5.x. Did you re-run vglserver_config after
installing VirtualGL 2.6.5?

I need some help with how to resolve the vglserver_config/vglrun
issue below.
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.
