Debugging VisRTX?
rgrunbla opened this issue · comments
Hello,
I'm trying to compile and use VisRTX on Linux (Archlinux, up-to-date), but I'm having trouble launching the provided programs (e.g. visRtxSampleBasic). A window opens, then closes, and the attached message is output. Graphic card is a Quadro M1200 Mobile, and log is attached.
How should I start to find out what is the issue?
Thanks,
Rémy

Hey,
which version of OptiX are you running? And where did it come from (since its in /usr/lib)?
Can you download the OptiX 6.5 SDK and try if the precompiled samples work for you?
Thanks,
Tim
Hey,
I'm running version 6.0.0.25650775-1, manually moved into /usr/lib (well not manually but using an AUR package). I'll check with 6.5 tonight, thanks for the advice.
Using 6.5.0, I still get the same behaviour with VisRTX. Using precompiled samples, it sometimes works (for example, optixSphere) but sometimes does not:
SDK-precompiled-samples % ./optixParticles
OptiX Error: 'Unknown error (Details: Function "RTresult _rtBufferCreateFromGLBO(RTcontext, unsigned int, unsigned int, RTbuffer_api**)" caught exception: Encountered a CUDA error: cuGLGetDevices returned (999): Unknown)'
The /usr/lib/libnvoptix.so.1 file comes from the "nvidia-utils" package of Archlinux, which is a dependency of the driver.
Is it possible you have some GPU switching in your laptop, like Optimus?
If this is the case, try to disable the internal GPU and force running the OptiX/OpenGL app on the dedicated card.
Yes, indeed, it was the culprit. Now, everything works, thanks (precompiled binaries, as well as recompiled VisRTX :) ).
Thanks!
