I have an Asus K52F with and Intel HD graphics chip. I used the SNA enable trick on 12.04 and it worked without the PPA needing to be added. I've been going at it for 3 days now on 12.10 and tried everything I can think of or find online but it still shows up as Unknown Graphics under Settings --> Details. Does anyone know anything that can fix this. The i915 kernel driver is loading if this makes a difference I don't now.
