Using xorg w/o an xorg.conf file
With the 2.6.28 kernel series, you can use xorg without xorg.conf. This works fine if you don’t plan to use 3d graphics (nvidia in my case). If you do you will need a minimal xorg.conf. This is what I ended up with:
Section “Module”
Load “glx”
Load “fb”
Load “wfb”
EndSection
Section “Device”
Identifier “nVidia Corporation G98 [GeForce 8400 GS]”

Busid “PCI:1:0:0″
Option “AddARGBGLXVisuals” “True”
Option “DPI” “1366 x 768″
Option “RenderAccel” “True”
Option “TripleBuffer” “True”
Option “AllowGLXWithComposite” “True”
Option “DisableGLXRootClipping” “True”
Option “BackingStore” “True”
EndSection
Section “Extensions”
Option “Composite” “Enable”
Option “RENDER” “true”
Option “DAMAGE” “true
EndSection
