_I_ am surprised, I've not had to reconfigure for a screen for some
time. Perhap you run a higher resolution than my eyes can cope with.
Pick and choose from this:
# Xorg configuration created by system-config-display

Section "ServerLayout"
     Identifier   "single head configuration"
     Screen    0 "Screen0" 0 0
     InputDevice   "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
     Identifier "Keyboard0"
     Driver    "kbd"
     Option    "XkbModel" "pc105"
     Option    "XkbLayout" "us"
EndSection

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

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

It works fine on my LCD screens running Scientifiuc Linux 5 (A RHEL 5
clone).

Give this a go:As root
X -configure

and if that works, take its advice.
