It looks like either you didn't install the Nvidia driver correctly, or, more likely, you are trying to run ChimeraX remotely.  That is not supported due to all of the ways it can fail.  Ideally, you would run ChimeraX directly on the computer with the graphics card.  So that means that you would copy the data from the remote system to your laptop/desktop with the  graphics card in it, and run ChimeraX locally.   If you must run ChimeraX remotely, then you need a remote access solution with 3D graphics support, like VirtualGL (and a graphics card in the remote computer).  There are other solutions.  You need to work with your system administrators to find a good solution for you.

    Good luck,

Dear Developers,

Hope this email finds you well.

I have encounter an issue regarding the GPU driver usage for chimeraX.

The issue is that the model and density movement is very choppy at step size 1, with a box size of 400.

Here are some information on the software that I am using.

Downloaded Software:

Ubuntu 22.04 (Linux)

ucsf-chimerax_1.9ubuntu22.04_amd64.deb

This is my current nvidia driver and cuda version:

NVIDIA-SMI 560.35.05              Driver Version: 560.35.05      CUDA Version: 12.6

It came to my attention that it is not utilising GPU upon running "graphics driver" on chimeraX, which outputs:

graphics driver

OpenGL version: 4.5 (Core Profile) Mesa 23.2.1-1ubuntu3.1~22.04.3

OpenGL renderer: llvmpipe (LLVM 15.0.7, 256 bits)

OpenGL vendor: Mesa

additionally, it is not showing up under nvidia-smi when I am running the program.

Is there any solutions to this issue?

Thank you in advance.

Regards,
Eddie
