I have a problem with using my RTX 2070 Super for rendering in Houdini. I'm using MX Linux 23 with the nvidia driver version 525.125.06 and I'm checking the usage with nvidia-smi.
I tried the view port karma preview and the render to disk with the karma node set to XPU. But there is no GPU usage, it stays under 10% usage. When I move around in the view port or start a smoke sim with open-cl the usage increases up to 40%.
The necessary packages should all be installed because in Blender when I render on the GPU the usage goes up 99%.
I really hope someone can help me solve the problem, so I can finally stop using windows.

What do you see in the top right of the viewport?
Something similar to this?
https://www.sidefx.com/docs/houdini/solaris/karma_xpu.html#viewport [www.sidefx.com]
Can you see the "Optix" entry there?
If so, what % is it showing? It indicates how much of the rendering is being contributed to by the GPU vs the CPU. Something over 80% is what I'd expect.

No I can't see Optix there.

Ah, ok.
Then CUDA/Optix is failing to initialize.
Try rendering offline using the "karma" command but with a high verbosity level. You might get some more information about why XPU cannot initialize the Optix device.
Or you could wait for H20 and try again (it has better error reporting about failed devices)
But be warned it requires 535 driver minimum :/

ajz3dbriansWell, this is an unpleasant surprise.

535 wasn't even uploaded to Debian Experimental repository yet, and it will probably take half a year for this, or a newer version, to even reach Unstable. Are you sure this is not a typo?
535 is already pretty old. The current driver is version 545

I started Houdini in the terminal and got this error when I started rendering.
