    Depending on your distro you will find the config file in /etc/X11/xorg.conf or /etc/X11/XF86Config-4 .I believe the part you are looking for is this
    Code:
    Section "Monitor"
      Option       "CalcAlgorithm" "CheckDesktopGeometry"
      DisplaySize  360 270
      HorizSync    30-95
      Identifier   "Monitor[0]"
      ModelName    "1920X1200@75HZ"
      Option       "DPMS"
      VendorName   "--> LCD"
      VertRefresh  60-75
      UseModes     "Modes[0]"
    EndSection
    I don't normally mess with this where I can involve it, and always make a backup beforehand. It is I believe the VertRefresh section you are looking for....


    ...All at your own risk my friend

    If you haven't done so already, you might want to make sure your monitor will support that refresh rate, as there are some that won't.

    Grab your monitor's vertical and horizontol sync rates, and edit /etc/X11/xorg.conf or XF86Config-4

    Here is my configuration of the monitor in /etc/X11/xorg.conf
    Code:
    Section "Monitor"
            Identifier   "Monitor0"
            VendorName   "Monitor Vendor"
            ModelName    "Samsung SyncMaster 765MB/715MB/CD175D(P)"
            DisplaySize  320        240
            HorizSync    30.0 - 85.0
            VertRefresh  50.0 - 160.0
            Option      "dpms"
    EndSection
    The HorizSync and VertRefresh are the same with the manufacturer specification. But in FC4, it only allow me to set the Refresh rate up to 85Hz, at 1024x768. I want to set to higher rate. Anyone who use at the higher refresh rate, please show me your monitor section (CRT model) in xorg.conf for example, thank you.
