GPU acceleration on Lenovo T470 doesn't work in apps

According to the Lenovo T470 Arch page hardware acceleration for i965 is suposed to work using va-api, but in fact, at least in vlc and mpv it doesn't work.

After configuring the environment variables as:

>>> cat /etc/environment                                                                                                                                                    
#
# This file is parsed by pam_env module
#
# Syntax: simple "KEY=VAL" pairs on separate lines
#
LIBVA_DRIVER_NAME='i965'
VDPAU_DRIVER='va_gl'

vainfo output:

Re: GPU acceleration on Lenovo T470 doesn't work in apps

Are you using wayland or xorg? As far as I understand, vdpau doesn't work in a wayland environment.
https://github.com/i-rinat/libvdpau-va- … -283436750

At least for mpv, you should be able to choose the va-api backend instead of vdpau and the wrapper, though

Re: GPU acceleration on Lenovo T470 doesn't work in apps

Well, it loads the VDPAU correctly on my Thinkpad X230 just fine (I didn't try to check for aceleration in apps) with exactly the same configuration and Gnome 3 as well.

In the Thinkpad T470 it doesn't even load VDPAU. So there is something here at play other than wayland.
