It's gonna take someone who knows Linux and ACPI better than I to integrate support for the R2. But, I think I'm barkin' up the right tree.

I believe that vga_switcherroo would work for us if the method were defined in the main DSDT. If someone updated the code to look in the SSDT, maybe it would work?

Beyond my skill level or time to learn the skill at this point. But.. as I get time I continue to tinker
I'm wondering if you've seen the post at http://linux-hybrid-graphics.blogspo...sus-u43jc.html

It looks like we may have a similar "problem" with the line
If (LEqual (\_SB.PCI0.P0P2.PEGP.OMPR, 0x03))
Although I'm not entirely sure. Busy recompiling my kernel with ACPI debug support, and hopefully messing about with the SSDT will yield some results
