Xorg and multiple graphics cards

[martin f krafft]

Hi folks,

After upgrading to 7.4, I got an ABI mismatch when using the old 6.6
ATI driver to control the two Radeon cards I have in my machines,
which are combined with Xinerama into a triple-monitor setup.
I could also not compile the 6.6 tip against the new 7.4 code [0].

I was informed that X still does not support XRandR across multiple
cards yet. Thus, I have two choices:

1. roll back and stay with X 7.3 + ATI 6.6
2. forget triple-head and return to dual-head

(2) is clearly not an option, so I am doing (1), but I am also
reminded of this thread on the issue:

  http://www.nabble.com/setting-up-xrandr-with-two-graphics-cards-td13835871.html

and I was wondering if there's a roadmap ahead and multi-card XRandR
is not too far down the line. Can anyone estimate, when it will be
supported?

Cheers,
Martin


0. This is the compiler error I get when compiling the xf86-video-ati 6.6
branch [a5570f3] against X 1.6.0 headers:
