[SOLVED] libva-intel-driver

Hello, this is my first post here, and I hope I am posting in the correct place.

I opted not to install the intel driver, and instead fall back on the modesetting driver.

The question which I have: Is the libva-intel-driver still required for hardware video acceleration when using the modesetting driver?

Thanks in advance for your answers

Re: [SOLVED] libva-intel-driver

xf86-video-intel (I guess this is what you mean with "the intel driver") and libva-intel-driver are two different things. The first one is for xorg, hw-accelerated drawing. The second is for using vaapi, a hw acceleration library that can be used for video decoding and things like that.
Modesetting uses glamor for hw acceleration, so no, you don't need libva-intel-driver to run xorg properly. The other way round works, too. You can make use of vaapi acceleration on a system without xorg.

Re: [SOLVED] libva-intel-driver

You should still need to install VA-API/VDPAU drivers (e.g. libva-intel-driver) for hardware accelerated video decoding to work with modesetting driver. You may have to also determine the correct driver with environment variables: https://wiki.archlinux.org/index.php/Ha … figuration

This should be easy enough to test yourself: Play a video, or use vainfo/vdpauinfo and see if things work.
