Touchpad not working on LUBUNTU laptop, why?

Question

Windows

The touchpad / keyboard does not work on my laptop (Sony Vaio VGN-NS235J). It happens like this

• If you install Windows XP
  Both the keyboard and touchpad do not work!
  
• If you install Lubuntu
  Only the touchpad does not work!
  

Important: the laptop does not have ACPI. Lubuntu is loaded via the "acpi=off" parameter. A Windows was installed via F7

Answer 1

There are no drivers.
For Windows XP, see the manufacturer's website.
Under Linux, try to look in the "Proprietary Drivers" program, if it's not there, then under Linux the touchpad will not start.
