Re: Radeon / PowerPC (iBook G4) / Help sought with weird colorization of External LCD

Hi Michel and Bin,

The driver no longer supports traditional ("Zaphod" style) dualhead
configurations but just RandR 1.2. See
http://bgoglin.livejournal.com/9846.html or
http://www.intellinuxgraphics.org/dualhead.html .
Thanks very much for the assistance.

I have now managed to get a dual-head setup going on the iBook with the
new Xorg + new Xrandr setup.

Haven't quite fixed the mouse cursor yet but hopefully that's not too
hard (cheers Bin!).

As far as the colours go though, correct me if I'm wrong but the new Xrandr
setup uses one set of "gamma gear" (CLUTs?) for *both* screens.
Would this indeed be the case?

Which means I can no longer specify corrective profiles individually using "xcalib".
Any change to the internal LCD profile affects the external monitor too.
And the colours on the external monitor are pretty funky!

Where do I go from here?

Thanks & Regards,
