No nvidia .so driver in /usr/lib/dri when needed to enable VA-API

Hello,
I have an inkling that my computer does not have any hardware-acceleration enabled for 1660 Ti Turing, since I'm getting terrible FPS drops on games compared to a Windows session on the same hardware.

09:00.0 VGA compatible controller: NVIDIA Corporation TU116 [GeForce GTX 1660 Ti] (rev a1)
        Subsystem: Gigabyte Technology Co., Ltd TU116 [GeForce GTX 1660 Ti]
        Kernel driver in use: nvidia
$ grep -iE 'vdpau | dri driver' /var/log/Xorg.0.log
[     9.721] (II) NVIDIA(0): [DRI2]   VDPAU driver: nvidia

This is partially confirmed since running:

$ vainfo
Trying display: wayland
Trying display: x11
libva error: vaGetDriverNames() failed with unknown libva error
vaInitialize failed with error code -1 (unknown libva error),exit

I tried to follow the instruction at https://wiki.archlinux.org/title/Hardwa … ing_VA-API however I'm stuck at this point:

You can override the driver for VA-API by using the LIBVA_DRIVER_NAME environment variable:

    Intel graphics:
        For libva-intel-driver use i965.
        For intel-media-driver use iHD.
    NVIDIA:
        For Nouveau use nouveau.
        For NVIDIA VDPAU use vdpau.
        For NVIDIA NVDEC use nvidia.

There are no nvidia drivers located at /usr/lib/dri.

$ ls /usr/lib/dri
crocus_dri.so  i915_dri.so  kms_swrast_dri.so  r300_dri.so  radeonsi_dri.so  virtio_gpu_dri.so  zink_dri.so
d3d12_dri.so   iris_dri.so  nouveau_dri.so     r600_dri.so  swrast_dri.so    vmwgfx_dri.so

I did find an nvidia driver elsewhere, at /usr/lib/xorg/modules/drivers/nvidia_drv.so, so I tried to set my environmental variables accordingly:

$ echo $LIBVA_DRIVERS_PATH 
/usr/lib/xorg/modules/drivers/nvidia_drv.so
$ echo $LIBVA_DRIVER_NAME
nvidia

However, I'm still getting the error from vainfo

$ vainfo
Trying display: wayland
Trying display: x11
libva error: vaGetDriverNames() failed with unknown libva error
vaInitialize failed with error code -1 (unknown libva error),exit

Here's my full journalctl from the current boot.

Movieplayers & browsers tend to care about HW Videoacceleration, but most games don't .

Your HW va setup is wrong though.

$ pacman -F nvidia_drv_video.so
extra/libva-nvidia-driver 0.0.11-1
    usr/lib/dri/nvidia_drv_video.so
extra/libva-vdpau-driver 0.7.4-6
    usr/lib/dri/nvidia_drv_video.so
multilib/lib32-libva-vdpau-driver 0.7.4-7
    usr/lib32/dri/nvidia_drv_video.so
$ 

( first run sudo pacman -Fy if needed )

You probably are missing libva-nvidia-driver .

Thanks for a reply. I appreciate you taking the time to help me.

I installed the package and now I do find nvidia_video_drv.so in /usr/lib/dri. My ~/.bashrc contains:

# Re-configure what kind of a driver hardware graphical acceleration uses
# as per https://wiki.archlinux.org/title/Hardware_video_acceleration#Configuring_VA-API
export LIBVA_DRIVER_NAME=nvidia

I resourced my bash by running;

$ source ~/.bash_profile

However, the vainfo error remains.

I installed the package

"the"?
Which one? (They conflict with each other)
Try libva-vdpau-driver and set the driver to vdpau
