[vox-tech] monitor troubles

[Mark K. Kim]

You can add all modes, in the order of your preference, like this:

      Modes      "1024x768" "800x600" "640x480"

so you don't have to try each one.

Anyway, that's the sidenote.  Since you got the sync information, set the
hsync and vsync rates in XF86Config:

      HorizSync     30-100
      VertRefresh   50-160

Furthermore, your video card needs to be supported by X.  It looks like
Intel has their own driver and a support page:

   http://support.intel.com/support/graphics/linux/graphics.htm

Neat.
