imac G5 radeon 9600 spanned desktop (managed somehow to doit

[tork1974]

I am currently trying to get a spanned desktop working with an external monitor
with my imac G5, initially the imac G5 cannot have spanned desktop
but this is easily remedied with a patch:

http://www.rutemoeller.com/mp/ibook/ibook_e.html

This patch made my imac able to span desktop on two monitors in Macosx
but the real deal i would like to do is make this happen also in gentoo.

i did find some hints on different ways to do this at this page:

http://gentoo-wiki.com/HOWTO_Dual_Monitors#ATI

But so far no luck.

I will continue to try to find some resources on this, but if anyone
does have any experience i am hoping for some help here.



x86config: <--works somewhat, but have a black sop to the right of the 1280x1024 screen, i tried different ways, but the solution eludes me
