Compaq nx8220 laptop (1680x1050)
ATI X600

SUSE 11.0

I am trying to configure KDE or Compiz with dual screen
big desktop support.

I can run kde4/compiz on ONE screen with effects.
I can run Icewm WITHOUT effects in Xinerama mode on TWO screens.
Both with the listed xorg.conf

THIS IS THE PROBLEM: What I CANNOT do is to run KDE/3/4 or compiz with Xinerama and/or effects on TWO screen.

* I have added the ati/suse directory to my repository and installed the drivers.
* as root I do

aticonfig --initial=dual-head --screen-layout=left
aticonfig --dtop=horizontal,reverse
aticonfig --resolution=0,1680x1050
aticonfig --resolution=1,1680x1050
sax2 -r -m 0=fglrx

* Starting catlyst I see big mode for both screens, the resolution is correct 3360x1050.
* Starting sax2 I see the correct resol for both screens, 3dsupport, dual head and xinerama configured.
All seems ok.

Starting kde/3/4 I get 70% of the two screens covered as one
big screen. This area alternates between correct and a lower resolution at the same time depending on where your curser is.
Updating of the screen does not work with large areas going black under the curser as you move around.Compiz is the same,
but with effects enabled.

How can I get the desktop 100% of the two screens and updating
properly?
I have rebooted 1 million times and tried all sorts of changes
to the xorg.conf but my nice screen remains useless.

Thanks in advance.
