Hi
I have a bug reported that I would like to have some help with. Pointers
in what area the bug can be. (if possible)
#1299 messed up screen with intel_extreme driver
(http://dev.haiku-os.org/ticket/1299)
The external screen works but the internal are not ok, it looks like an
analog tv with the antenna not position right (the screen are dissorted)
I had a mail conversation with Philippe Houdoin and he pointed to that the
problem could be PLL
"considering the frame buffer content looks correct, means that the PLL
setup is quite screwed. :-)
"
it looks like those pll things are in mode.cpp and/or dpms.cpp
#define TRACE_ set on all files in this driver.
am I on the right track?
I will set more trace but so far the only output to syslog are this.
so right now I can't say if mode.cpp and/or dpms.cpp are used by my card
and perhaps that's the problem :).
