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.

It looks like you're not really getting data from the gmux in those
dumps. The address range should be correct based on your ACPI tables. I
have some ideas, but it won't be much longer until I can play with one
of these machines myself so it's probably easier if I try them out then.
Thanks,
Seth

allright, no worries. Delivery time can be quite long for these
machines, I waited for mine 5 long weeks.
Hope you get yours faster.
Cheers,
Francois

mode (corrupted), another problem for the use of the i915 driver
