Description Nicolas Mailhot 2006-01-21 15:30:33 UTC

xorg does not detect the heads in the same order than windows on a dual-dvi PCIE
X700

This is very user-unfriendly, this means on a dual boot system one of the two
OSs won't display any image unless it's tweaked manually to change the primary
monitor (hooking something else on the secundary head to see what's you're doing
meanwhile.

Most users will decide the blank system is broken instaed of hunting and fixing
the problem

More info in the xorg boog

Comment 2 Mike A. Harris 2006-01-23 17:54:35 UTC

That's because the display detection code in X, is not the same code that
is used in ATI's proprietary driver in Windows.  In order for this to be
changed, it will have to be done upstream by X.Org, and my understanding
is that it will require a complete rewrite of the ATI display detection
code, which is a huge mess, making this particular feature request
nontrivial.

Feel free to file a feature request in upstream X.Org bugzilla if desired.
