I'm starting to get really annoyed by the i830 (82830) driver support for my
laptop. In particular, I want to be able to turn on the external video, at
least in mirror mode. The BIOS can do it on startup (and does, if the monitor
or projector is connected), Windows XP can do it, but Linux can't.
I've tried to get the doco out of Intel, but never got anywhere. This is still
the preferred option, but I figure I need Plan B.
I figure if I can watch the right PCI registers, and toggle the mode under
windows, I can see which bits are flipped. Then I just write a really basic
utility to flop those same bits, and I'll be set. The hard part is that I
know absolutely nothing about development or debugging on windows. Is there a
tool I should use? Or is there a debugging mode built in?
