Intel HD Graphics with openSUSE 11.3

For example in 50-monitor.conf, substituting your own display’s values for HorizSync and VertRefresh:

Section "Monitor"
  Identifier "Default Monitor"

  ## If your monitor doesn't support DDC you may override the
  ## defaults here
  HorizSync 28-85
  VertRefresh 50-100

  ## Add your mode lines here, use e.g the cvt tool

EndSection

For example in 50-screen.conf, removing any invalid resolutions:

Section "Screen"
  Identifier "Default Screen"

  Device "Default Device"

  ## Doesn't help for radeon/radeonhd drivers; use magic in
  ## 50-device.conf instead
  
  Monitor "Default Monitor"
  DefaultDepth 24
      SubSection "Display"
          Modes "1600x900" "1366x768" "1024x768" "800x600"
              Viewport   0 0
              Depth     24
      EndSubSection
EndSection

You could try first only implementing the changes to 50-screen.conf
