Laptop touchpad stopped fucntioning

[oneeyedelf1]

Well I recently did an apt-get dist-upgrade and the double tap on my laptop touchpad stopped working.
I have a synaptics (might be spelled synaptix) touchpad, and a dell latitude CSx laptop. I know I have to change something, I just dont exactly know what or how to.

Any replies would be helpful

I know that when I boot knoppix into kernel 2.6 my touch pad starts malfunctioning. I cant offer any other help im afraid but that may be enough to put you in the right direction.

I have this exact same problem with my Toshiba Satellite Pro's touchpad when I went from Knoppix 3.7 to 3.8.1. Anyone have a solution?

I'm not sure if you are having the same problem as me but mine was fixed but
telling Knoppix it's a mouse instead of a touchpad. I tryied all the touchpad add-ons
I could find but still couldn't get my scroll to work, so I just gave up and put this in at boot.

I've been unable to double-click on the touchpad since kernel 2.6 .

Recently I read on a yahoo group [linux on dell laptops] that passing "psmouse.proto=exps"
to the kernel fixes it.
psmouse.proto=exps

I've tried it as a cheat code w/ both knx3.7 and knx3.81.
It's worked for me on my dell latitude cpi r400gt laptop.

good luck!
