Dual boot mxlinux doesn't recognize optix

I just installed mxlinux kde version, and blender through steam doesn’t recognize optix even though I have a 2700 super. I have the latest nvidia drivers installed.

I couldn’t get my blender plugins to install via flatpack version of 3.1 oddly but steam is fine.

Hi.
Does it only happen with OptiX? What about CUDA?
What happens with official version downloaded from blender site? (Download, extract to a folder and run “blender” file there)

You open the linux terminal and share here the output of:
sudo lshw -c video

and

cat /proc/driver/nvidia/version

I belive blender only offers a tar and snap?

Download the tar.xz, unpack the archive to a new folder. Enter the folder and there double click on “blender” file and test if OptiX and CUDA are available

Even with the tar.xz only cuda is available

I’m not sure if your distro is based on Ubuntu or Debian packages. You open your package manager and search for the word “optix” and check that it is installed. I guess it could be “libnvoptix1” and “libnvidia-rtcore” for Debian or "libnvidia-gl-510"for Ubuntu (510 because it’s your driver version)

Anyway, in Ubuntu that package is installed by default with driver installation. Not sure for Debian.
(All this if you installed nvidia driver from distro packages)

Debian based. Not seeing it in the package installer.

Have you installed nvidia driver from .run file or from distro packages?

In the meantime you could ask in the MX Linux forum. I have found other similar cases but I am not sure if it has the same causes as your problem:

Or if you are new to Linux maybe you could try installing another linux distro. You try a user friendly distro with a large user base and well maintained.
