      My problem is that, when I set 1280x1024 or any other resolution
      that is not 1400x1050 in section "screen", I was not able to login
      in the graphic mode by startx or by init 5 in /etc/inittab.
      And pressing fn-f8 didn't help.
      Unless I plug in an external monitor after boot, then the X will
      show up at the external monitor, after pressing fn-f8 several times,
      the X will come back to my notebook-LCD, and it gave me the right
      resolution I want.

      It seem that resolution other than 1400x1050 work,
      but only if an external monotor exist.

      Anyone have any ideal about this?

      Thanks
