Hello.

I wrote this tutorial some time ago because I wanted that Blender was able
to recognize CUDA and the Nvidia driver directly within the linuxulator :

https://www.reddit.com/r/freebsd/comments/1118eae/how_to_install_the_nvidia_driver_5257801_cuda_12/

I was inspired by this tutorial :
https://gist.github.com/Mostly-BSD/4d3cacc0ee2f045ed8505005fd664c6e

someone found my tutorial and created this github :

https://github.com/spfcraze/Nvidia-Drivers-linux

He says that he created a Python script for updating Nvidia drivers on
CentOS 7 and Ubuntu. That's nice,but it can't work. Why ? please give a
look to an old post created by me some time ago and you will see :

https://www.reddit.com/r/freebsd/comments/11431bi/how_to_blacklist_the_nouveau_driver_within_the/

since the nouveau driver can't be blacklisted within the Linuxulator
because it's impossible to run "sudo update-initramfs -u" inside of it. For
this reason,I would ask if in your opinion the nouveau driver can be
blacklisted directly in FreeBSD or in some other way.

FreeBSD does not contain the nouveau kernel module so there is nothing to
blacklist.

These libGL errors are from Mesa libGL, which is trying to use the
userspace part of nouveau (which is part of the Mesa project),
presumably based on Nvidia GPU's PCI ID being known to Mesa, despite there
being no nouveau kernel interface available.

Since I'm trying to use Nvidia's binary driver (the only one which works on
FreeBSD), Blender should have never loaded Mesa's libGL in the
first place - there is most likely a configuration problem here with
libglvnd, the component responsible for choosing the correct libGL
implementation.

When Blender fails to detect CUDA this has nothing to do with libGL and
absolutely nothing to do with nouveau.

Smplayer behaves the same as blender. I think this is a general behavior.
Check below what happens when I run it within the linuxulator :

root@marietto:/mnt/zroot2/zroot2 # chroot /compat/ubuntulunar /bin/bash

root@marietto:/# smplayer

QStandardPaths: error creating runtime directory '/var/run/user/1001' (No
such file or directory)
This is SMPlayer v. 22.7.0 (revision 10091) running on Linux
libGL error: glx: failed to create dri2 screen
*libGL error: failed to load driver: nouveau*


Can you figure out a method to do what I want to do ? If we are able to
"connect" the nVidia driver to the CG / graphic tool instead of the nouveau
one,a lot of cool features will be unfrozen on FreeBSD. For example we
could try to run Unreal Engine 5 within the linuxulator,Davinci
Resolve,Maya 3D,a lot of cool stuff will use the nVidia driver + CUDA and
it will work great. That's because unfortunately Nouveau does not support
CUDA.


Thanks.
