I have Dell Inspiron 4000 and the touchpad is really sensitive. If my fingers give it the slightest touch as I type, it thinks that I have clicked. Is there a way to make it less sensitive?

It would help to solve the problem.

If it is Synaptics, there are good drivers in the wild, and configuration is well explained. So far this is what I've been using, but everything relies on your specific hardware, I guess.

I saw this the other day on another URL, and it told which file to edit, changing "resolution". I did not get time to do it, and now cannot find the note which told the filename to fix.

It is a synaptic touchpad. I'll search for the drivers.
Thanks

Here it is :

Im using the synaptics driver, In the Xfree86-4 config file, change MaxTapTime=180 to MaxTapTime=0 to disable tapping to be a click.
