So now that i have everything else working on this x230, I'm taking a fresh look at the acpi brightness support. I'm in the same boat - only PEG works. But I have integrated graphics only, rather than both integrated and nvidia graphics. A cursory reading of the linux acpi and video / video-detect code doesn't show anything terribly obvious. I may end up downloading and booting ubuntu on USB at some point to see what the ACPI device tree looks like, in case they are somehow linking vgapci0 correctly to SB.PCI0.PEG.VID. Any other ideaS? -a
