18601	Chimera Not Using Graphics Card	andhale@…	Greg Couch	"{{{
Hello Chimera Team,
I just did a fresh install of kubuntu (ubuntu distro w/ KDE plasma in place
of gnome). I installed the newest nvidia driver, and it appears to be
installed correctly according to the nvidia-smi command (driver
version 575.57.08
) Despite this. ChimeraX (also fresh install version 1.10.1) does not
appear to be using my graphics card. When doing some light monitoring of
GPU performance while using chimera, I don't see it utilizing the gpu
(sorry I did not script the command so I don't have more info for you).
After some sleuthing I ra the graphics driver command and got this output
OpenGL version: 4.5 (Core Profile) Mesa 25.0.7-0ubuntu0.25.04.1
OpenGL renderer: llvmpipe (LLVM 19.1.7, 256 bits)
OpenGL vendor: Mesa
After some sleuthing I see the the llvmpipe means it is using my CPU. Which
seems to confirm my previous suspicions. Games I have run on my machine
seem to be using the GPU fine which makes me believe it is a problem with
the handshake between chimera and my driver. Is there some kind of command
where I can point to the driver verbosely or something else of that nature?
Thank you,
Andrew  Hale
