I checked it on my laptop.

I get it on my NVIDIA machine, but not on my Intel machine.

I think it's a difference in the video driver.

Hmmm... I guess We have to install libva-utils separately.

CER>  And what is the correct driver name? :-?

In your case, as per your previous email, iris.

It's unlikely.

Please show these results;

1. $ cat /etc/os-release

2. $ inxi -Ga

3. $ rpm -q Mesa-libva

4. $ rpm -q libva-utils

5. $ LIBVA_DRIVER_NAME=iris vainfo

Best Regards.
