Wrong graphic driver running

Hi,
I think I have an issue with my graphic driver and want to confirm that.
Since a cople of month’s, I had the feeling like my display was slugish then I ran some test yesterday an it look’s like the wrong driver is running. I am runnning an NVIDIA GF100GL [Quadro 4000] and all is up to date kernell 5.10.19-1. From the wiki the info that the command return is for a intel driver not Nvidia. Is that correct?

Thx

Try "sudo mhwd -a pci nonfree 0300" in a terminal.

I did re-install it yesterday…

Do you have linux510-nvidia390xx installed? Sometimes, this package is not installed by mhwd automatically.

Just do pacman -Qs nvidia and post the output here.

If you have to install linux510-nvidia390xx, do not forget to update the kernel image with sudo mkinitcpio -P afterwards.

OpenGL renderer string: llvmpipe (LLVM 11.1.0, 256 bits)

means that you are using a software OpenGL renderer. After having installed linux510-nvidia390xx, restart the computer and then check your /var/log/Xorg.0.log.
If there is some error saying

Failed to initialize the GLX module;

you will have to amend /usr/share/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf. The contents of this file should look like

Section "OutputClass"
    Identifier     "nvidia"
    MatchDriver    "nvidia-drm"
    Driver         "nvidia"
    ModulePath "/usr/lib/nvidia/xorg"
EndSection

After that change, restart at least X or the entire computer.

In order to check whether all these actions made any change, issue the glxinfo | grep OpenGL command again.
The output should read like

Failed to initialize the GLX module; please check in your X

Is not exactly like what you posted.

Section “OutputClass”
Identifier “nvidia”
MatchDriver “nvidia-drm”
Driver “nvidia”
EndSection

So I append to what you posted. I will see if that did the trick!

All good! Thx
