Hi Matthias and Matthew,

I am right in thinking that reading the DSDT tables for hybrid
graphics laptops is sufficient to infer their workings?
I've been compiling a list of hybrid graphics laptops and been asking
people to provide their DSDT tables
in this bug report:
https://bugs.launchpad.net/bugs/312756

So far, I've identified 12 laptops, and we've got DSDT tables for 4 of them:

Please let me know if you think we should be asking any other info,

Cheers,

Albert.
