I am using the snapshot from last week on my workstation which has two monitors and the following card

vga1 at pci3 dev 0 function 0 "ATI Radeon X1600" rev 0x9ea

I can use both monitors using xrandr with the command

xrandr --output VGA-0 --auto --left-of DVI-0

and the xorg.conf setting

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        DefaultDepth    24

        SubSection "Display"
                Depth   24
                Modes   "1920x1080" "1680x1050" "1600x1200" "1280x1024"
"1024x768"
                Virtual 3840 1080
        EndSubSection
EndSection

If I use KDE, the xrandr command I invoked does not seem to have an effect and so I cannot use both monitors. But with X (when I run startx) I can use both.

If you have any insight into this please let me know.
