Error: couldn't get an RGB, Double-buffered visual


We have a GeForce RTX 2070 within a Supermicro server running Centos 7.6 If I remote onto the system and try to run “vglrun glxgears” I can receive many different errors, depending on what I try.

Error: couldn’t get an RGB, Double-buffered visual
libGL: screen 0 does not appear to be DRI2 capable
[VGL] 261: Connection refused

I’ll attach nvidia-bug-report.log.gz

I have tried the OS nvidia drivers, and the latest .run from the nvidia site.

Unfortunately, no xorg logs or config files are included in the logs but there’s no Xserver running on the nvidia gpu.
If you don’t have a monitor connected, you’ll have to create an xorg.conf with

Option "UseDisplayDevice" "none"


Option "AllowEmptyInitialConfiguration" "true"

to let the Xserver stay alive.
