OpenGL uses MESA for rendering instead of nvidia drivers-KDE

Code: Select all

$ glxinfo | grep -i opengl:

OpenGL vendor string: Mesa
OpenGL renderer string: llvmpipe (LLVM 20.1.8, 256 bits)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 25.1.6
OpenGL core profile shading language version string: 4.50
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:

OpenGL shading language version string: 4.50
OpenGL context flags: (none)
OpenGL profile mask: compatibility profile
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 25.1.6
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20

$ lspci -k -d ::03xx:

VGA compatible controller: NVIDIA Corporation TU116 [GeForce GTX 1660 SUPER] (rev a1)
   Subsystem: ASUSTeK Computer Inc. Device 8787
   Kernel driver in use: nvidia
   Kernel modules: nouveau, nvidia_drm, nvidia 

Feel free to ask me for additional infos, that would really help. Thank you

[SOLVED]
this was solved by:

Disable Direct Rendering Manager (https://wiki.gentoo.org/wiki/NVIDIA/nvi ... ot_enabled)

add user (you) to the "video" group (https://wiki.gentoo.org/wiki/NVIDIA/nvi ... ermissions)

Is it wayland or X11 ?

A quick search shows most of the time this occurs because the Nvidia driver is not actually in use (such as in a hybrid graphics situation the nouveau driver is being loaded instead) or when someone is attempting to use the machine remotely.
Maybe you can provide some more information about your setup.
Does this machine have hybrid graphics (or only one Nvidia GPU)?
Can you confirm that the Nvidia proprietary driver is in use (as opposed to nouveau)?
Is this a custom kernel or a stock kernel?
What is the output of:

Code: Select all

equery u nvidia-drivers

Does nvidia-smi or nvidia-settings appear normal or offer any output that might give any useful information?
Have you reviewed the wiki to make sure you have configured everything correctly?

1.Yes my machine only have 1 dedicated GPU (nvidia)
2.

Code: Select all

$ lspci -k -d ::03xx:

   Subsystem: ASUSTeK Computer Inc. Device 8787
   Kernel driver in use: nvidia
   Kernel modules: nouveau, nvidia_drm, nvidia 

3.This is stock kernel (gentoo-kernel-dist) with Nouveau unbulit to the kernel (using snippet - # CONFIG_DRM_NOUVEAU is not set)
4.nvidia-smi appears to be nornal and nvidia-settings will open a gui-setting panel for nvida
4.I can't confirm configuration is correctly configiured because i'm using a Distrubition kernel (not binary)
