Hi Eric,

Before the release of OpenChrome Version 0.4.0, I figured out the cause of the
functional regression you have reported.
I believe this was related to the detection of a LVDS FP (Flat Panel) primarily
meant for laptops, and I found ways to automatically detect FPs without
interfering with the detection of other display devices like VGA.
What I believe happened was that when I moved to all automatic detection of
display devices, all devices were running through the code that will detect a
FP, and for your particular system, this was causing problems since the
previous developers were doing some odd things to "guess" the native screen
resolution of the FP.
I removed that portion of the code, and found a good way to detect the native
screen resolution of the FP before the new release.
I will say that you should give the current master branch code a try (Version
0.4.107), and see how it performs.
