issue with the parameter xconfig in kickstart file

[Eric Doutreleau]

Hi

i begin to switch to FC6 for my linux machine and i have the following
problem with the kickstart file.

I wold like to have a default resolution for the machine to 1024x768

i put that on my kickstart file

xconfig --defaultdesktop=GNOME --depth=24 --resolution=1024x768
--startxonboot
monitor --monitor="Monitor 1280x1024"

but the xorg.conf file is not configured.
on the machine here what i have

# Xorg configuration created by pyxf86config

Section "ServerLayout"
        Identifier     "Default Layout"
        Screen      0  "Screen0" 0 0
        InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
        Identifier  "Keyboard0"
        Driver      "kbd"
        Option      "XkbModel" "pc105"
        Option      "XkbLayout" "fr"
        Option      "XkbVariant" "latin9"
EndSection

Section "Device"
        Identifier  "Videocard0"
        Driver      "i810"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
        EndSubSection
EndSection
