My iBook has two heads
Finally, after two years of hacks , my iBook 2.2 knows how to multihead! And no silly clone mode only, totally different image and external output at 1600x1200 at 85Hz. This is nice! Thank you X.org people for version 7, thank you X Strike Force !
Update: well, now suspending fails and booting the machine results in a black screen in over half of the tries. Bah.
