I assume that you are using the GLX back end when the error occurs, but
I couldn't make the error occur with the EGL back end either. Which
nVidia driver version are you using? I can try to match your driver
version as closely as possible in case that has something to do with the
failure.
Otherwise, I think the only way forward is to get temporary access to a
machine on which the failure can be reproduced.

OK, that's an important data point. Now I just need to be able to

Hi DRC,
Just tested and it does not fail just using the local X server.
See attached output.

Do you mean on a local attached display? That won't be easy,
since this graphics workstation is part of a cluster located
far away from me or the user getting this bug.
I have just contacted Tecplot Support and I'm waiting for
their response and a trial license to test myself using my
own environment.
The 3D X server is on the VirtualGL server, which should be
the same machine on which Tecplot 360 is installed. Unless
the machine has been configured otherwise, the 3D X server
should be listening on Display :0.0, so try:
xauth merge /etc/opt/VirtualGL/vgl_xauth_key
LD_PRELOAD= DISPLAY=:0.0 ./Tec360_FlowViz_batch.sh
I remember to have to preload libvglfaker.so for starccm+ to
work properly. Anything similar perhaps needed here for
tec360? Just some more guessing. Worth a try?
Preloading libvglfaker.so is literally what vglrun does. I
am not trying to make Tecplot 360 work properly. I am trying
to make it fail.
Thanks,

I tried it with '$useVGL = 1' as well and was still
unable to reproduce the issue. (Note that, from the
point of view of the application, setting '$useVGL = 1'
in turbovncserver.conf or starting the TurboVNC session
with '-vgl' is the same as launching the application
with 'vglrun +wm'.)
I also tried with both CentOS 7.9 and CentOS Stream 8.
My CentOS 7.9 machine has a Quadro K5000 with driver
v470.xx. My CentOS 8 machine has a Quadro P620 with
driver v510.xx.
Is there any way that you could try running the Tecplot
batch job on the 3D X server without VirtualGL? If it
fails in the same way, then it isn't our bug.

Hi DRC,
sorry, I forgot to comment out that module command,
that would only add the Tecplot installation PATH to
the bash PATH variable,
But as I see from your output the tec360 command in
Tec360_FlowViz_batch.sh started fine, so it is already
in your PATH, so all good.
Did that tec360 run end without errors?
Is your setup also using $useVGL = 1; in
/etc/turbovncserver.conf ?
Just guessing possible differences.
Thanks for testing,
Richard

Please clarify how this is supposed to work.
'module load' is not a valid Bash command.

Hi DRC, hi all,
First, thanks DRC for this great software!
We are having some issue with Tecplot /
tec360 and VirtualGL:
Some system specs:
Rocky Linux 8.5
VirtualGL-3.0-20211119.x86_64
turbovnc-2.2.90-20211222.x86_64
NVIDIA Corporation GM204GL [Tesla M60]
Tecplot 360 EX 2021 R2, Version 2021.2.1.9698
(Feb 3 2022)
VirtualGL is configured with both GLX + EGL
back ends.
$useVGL = 1; in /etc/turbovncserver.conf
While trying to run tec360 on batch mode we
get the attached error output.
Here the last 10 lines:

"$0-bin" "$@"
Any ideas what is going wrong?
When running with tec360 option "--osmesa"
all runs fine, but it takes 17 min to run.
--osmesa
Bypass the OpenGL library and use the
LLVM OSMesa library for off-screen
image rendering. This option does not
require an X server connection.
Best regards,
Richard
