I have an ATI Technologies Inc Radeon IGP 330M in my Compaq laptop,
and I am using vers 6.8.2. Forst thanks a bunch for everything
this is the first radeon drivcer I have used that actually gives me
dual head and dri support with this hardware. My xorg.conf has:

Section "Device"
        Identifier      "ATI RADEON 0"
        Driver          "ati"
#       Driver          "radeon        =20
        VendorName "ATI"
        BoardName "Radeon Mobility U2"
        VideoRam 65536
        BusID "PCI:1:5:0"
        Option "AGPMode" "4"
        Option "DPMS"
        Option "AGPFastWrite" "On"
        Option "EnablePageFlip" "On"=20
        Option "MonitorLayout" "LVDS, CRT"
        Option "CRT2Position" "RightOf"
        Option "CRT2HSync" "30-94"
        Option "CRT2VRefresh" "50-75"
        Option "MergedFB" "true"
        Screen 0

My problem is two things:

1. If I run glxgears(or any other openGL code) on either of the two
monitors it changes back from Xinerama to cloned mode.

2. When there is no second monitor it still uses Xinerama mode.=20

So is there any way to fix my configuration so these two things dont
happen or is it just the limitation of the driver.

P.S. I also tried to run Xinerama using a dual screen configuration
but did not have any luck.

Thanks for any help.
