Seth,
[CC'd people, sorry we exchanged a few emails with Seth outside of the lists, I passed him the acpi tables and here are gmux dumps]
Allright. thanks for gmux-dump. There seems to be progress, as I can see the gmux dumps for the nividia-selected and intel-selected are clearly different (I did it twice to be sure, it checks out). The 2 dumps are at http://maumae.net/retina/gmux-dump_intel.dat and http://maumae.net/retina/gmux-dump_nvidia_only.dat I hope you'll be able to get something from these. Francois
