Hi I've installed everything ans set all the env vars according to the installation manual.

Here's what vainfo returns

libva info: VA-API version 1.14.0
libva info: User environment variable requested driver 'nvidia'
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so
libva info: Found init function __vaDriverInit_1_0
libva info: va_openDriver() returns 0
vainfo: VA-API version: 1.14 (libva 2.12.0)
vainfo: Driver version: VA-API NVDEC driver [egl backend]
vainfo: Supported profile and entrypoints

Also, here's what about:support shows:

Window Protocol	x11
Desktop Environment	ubuntu:gnome
Target Frame Rate	60
WebGPU Default Adapter	{
  "navigator.gpu": null
}
WebGPU Fallback Adapter	{
  "navigator.gpu": null
}
GPU #1
Active	Yes
Description	NVIDIA T500/PCIe/SSE2
Vendor ID	0x10de
Device ID	0x1fbb
Driver Vendor	nvidia/unknown
Driver Version	530.30.2.0
RAM	0

If I understand the output correctly, it should be working just fine. However the GPU utilization is 0% when i play youtube videos in firefox

Try setting NVD_BACKEND=direct, this is required as the NVIDIA drivers have a bug that prevents the EGL backend from working.

Thanks for answering so quickly. Unfortunately, doing that doesn't solve it.

elFarto commented

Can you run NVD_LOG=1 NVD_BACKEND=direct vainfo and paste the output here?

Maybe your version of libva is too old? I'm using libva 2.19.0 which works fine. (vaapi 1.19)

elFarto commented

The issue is that the Quadro T500 is not supported by NVDEC[1], therefore this driver will not work with it:
