[Fra B <frab1215@xxxxxxxxx>]

I'd like to ask this:
is there a way to exactly know what kernel module is using for a graphic
card?
How do I know intel card uses i915 module? And nvida ion uses nouveau?
What's shell command to know it?

Then, in your experience, the nouveau driver fully supports nvidia ion II?
Thanks!
