Hardware Transcoding

[VictorCorvo]

Hello,
I'm trying to get hardware encoding in Jellyfin.
I found the guide and installed vainfo libva2 and i965-va-driver.
But if I type vainfo to check if my hardware supports transcoding I get:

$ vainfo
error: can't connect to X server!
error: failed to initialize display

I'm using Ubuntu 22.04 on an intel N100.

lshw shows:
