Hi DRC,

Nvidia w/Ubuntu 20.04 is working now. VGL_USEXSHM=0 fixed it.
I added "vt10" to the Xorg command for the Nvidia+Ubuntu20.04 box, but
the console still blanks. The command used was "/usr/lib/xorg/Xorg :1
-config /etc/X11/xorg.1.conf vt10"
Thanks,
Jason

I recall now that the AMDGPU-PRO driver is not multi-GPU-friendly.
Specifically, it installs its own OpenGL libraries and DRI driver
under
/opt/amdgpu-pro rather than using GLVND, so the AMDGPU-PRO driver is
all-or-nothing with respect to a particular X.org instance. On my
RHEL
8 system, which has both a Quadro and a Radeon Pro WX2100, I had to
switch to the open source AMDGPU driver so I could attach the GPUs to
separate screens of the same X server. (AMDGPU is GLVND-aware but
AMDGPU-PRO is not.) In your case, however, since you're using a
dedicated X server for your AMD GPU, I would suggest manipulating
LD_LIBRARY_PATH such that it contains /opt/amdgpu-pro/lib* only when
starting or attempting to use your dedicated X.org instance (:2)
but not
otherwise. That may eliminate some of the error messages above,
although it's unclear whether those error messages are related to the
issue at hand. Definitely you need to make sure that LD_LIBRARY_PATH
contains /opt/amdgpu-pro/lib* before you attempt to use VirtualGL.

That seems like an unrelated issue, something amiss with the 2D X
server's MIT-SHM extension. You can try setting VGL_USEXSHM=0 in the
environment to work around the issue.

You should be able to pass 'vtXX' to the Xorg process, where XX is
the
number of a virtual console.
