Compile X from CVS and it'll work perfectly. The Radeon driver in 4.3.0
has poor support to dual-display Radeon 7000 cards.

Anyone managed to make the dual display feature work reliably on any ATI
card ? I need help with my XF86Config file.
I have 2 screens linked to a Radeon VE (7000) card in the AGP slot, I am
running Redhat 9 with XFree86-4.3.
The best I have managed is to get X running on both screens at once in
clone mode (both screen showing the same thing). However the second
screen goes off as soon as the mouse crosses a window (eg. xterm). To
get this to work I had to initialise the macine to runlevel 3 then
start X from the command line with xinit.
Trying to run KDE on runlevel 5, the second screen goes off as soon as X
is initialised.
This is the XF86Config file I was using, there are suggestions from a
lot of different sources in here (man pages, readme files and
suggestions on forums) but still no joy.
