  Hello Franco,

  The vesa drivers are written by the video chip manufactures
  so who ever made your video chip set in the laptop is the only
  place that you can get drivers from.

  Here is some information on toshiba web site
    http://www.toshiba.ca/support/Tsbs/200/tsb0235.htm

  If your laptop has a external video connector so you
  can connect a external video monitor, that would tell you
  if it the problem is to do with the fact that the built-in
  LCD monitor is a dual-scan monitor and that may not work
  with the drivers you have.
