Hello,

I set my xorg.conf file like below and I can then run:
vncviewer :0

and it just like I am sitting at my desk logging into kdm.

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

Section "Module"
         Load "vnc"
EndSection

Section "InputDevice"
# keyboard added by system-config-display
         Identifier  "Keyboard0"
         Driver      "kbd"
         Option      "XkbModel" "pc105+inet"
         Option      "XkbLayout" "us"
EndSection

Section "Device"
         Identifier  "Videocard0"
         Driver      "intel"
EndSection

Section "Screen"
         Identifier "Screen0"
         Device     "Videocard0"
         DefaultDepth     24
         Option "SecurityTypes" "VncAuth"
         Option "UserPasswdVerifier" "VncAuth"
         Option "PasswordFile" "/root/.vnc/passwd"
         SubSection "Display"
                 Viewport   0 0
                 Depth     24
         EndSubSection
EndSection
