Re: Poor performance with Alder Lake graphics (ThinkPad T16)

Jan,

Thanks for your suggestions, but this is not looking good.

Looks like VA-API may just be a non-starter on this system. Here is what I
get grom vainfo on the KMS screen:
Trying display: wayland
error: XDG_RUNTIME_DIR is invalid or not set in the environment.
Trying display: x11
error: can't connect to X server!
Trying display: drm
libva info: VA-API version 1.18.0
libva info: Trying to open /usr/local/lib/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_18
libva error: /usr/local/lib/dri/iHD_drv_video.so init failed
libva info: va_openDriver() returns 1
libva info: Trying to open /usr/local/lib/dri/i965_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

I am interested by hte first error. Is this possibly a side effect of
starting X from the console with the following .xinitrc:
xset fp rehash
exec ck-launch-session dbus-launch --exit-with-session mate-session

This has worked fine for many years, but reading up on XDG_RUNTIME_DIR
makes me suspicious that this may not be adequate.
