mouse doesn't work on xWindow

[<ximm@vodafone.es>]

Hello, after installing debian testing on my laptop, the touchpad
doesn't work , nor the PS/2 mouse. Although if I connect a serial mouse
it works.

If I start with knoppix v.3.4 all works fine, so I don't thik the
problem is the configuration file (XF86Config4)

Some help?

I attach a part of my XF86Config4 file.

Thank you very much.
