Short description of error
Blender/Cycles prints core dump when rendering with OPTIX and package
libnvidia-gl
is missingblender_331_coredump.txt
Exact steps for others to reproduce the error
sudo apt-get install -y nvidia-drivers-515
(alternativelysudo apt-get install -y nvidia-headless-515-server
)sudo apt-get install -y libxrender1 libxi6 libgl1 libglx-mesa0
./blender-3.3.1-linux-x64/blender splash_fox_2.90.blend -b -E CYCLES -f 1 -- --cycles-device OPTIX
This can be fixed by additionally installing
libnvidia-gl-515
.Would it be possible to gracefully check for the lack of the package and print a respective error message instead?

Will confirm as another user (report merged in above) has hit the issue and verified the same workaround - They needed to explicitly download the
libnvidia-gl-515
library separately.I wonder if this is some new requirement from the driver package? Unsure why it's not an automatic dependency though.
Might be worth mentioning, that the same problem and same workaround also applies for driver version 470. It's not a recent change in the driver package as far as I can tell.
Added subscriber: @LukasStockner
We can't really do anything about how the driver is packaged, but Cycles should just print a warning and fall back to CPU rendering instead of crashing.
From looking at the debug output, it seems like the Optix device initialization fails, but the path tracing logic picks the GPU codepath anyways:
