I just installed Ubuntu 12.04 on my SAMSUNG Series 7 NP700Z5B-S01UB. The touchpad worked out of the box and that has been awesome. But the touch pad's tap to click is too sensitive. It keeps selecting things as I'm just trying to move the pointer. I didn't have this problem with windows so this tells me that it can be configured to be less sensitive.
Need help doing this.
PS: I know turning off tap to click is an option but I don't want that.
PPS: I see various sensitivity sliders in the config but they seem to be at the lowest and mostly around acceleration of pointer not for tap sensitivity.

Open terminal and type in
synclient
and look at the value inPressureMotionMinZ
. Mine was set to 15, and the touch pad was very sensitive. Changing the value to 25 made a huge improvement in pointer stability when tapping.Simply enter
synclient PressureMotionMinZ=25
or what ever value you find comfortable.On to making the changes stick.
Now we need to make an xorg.conf file as 12.04 doesn't have one. So in terminal,
This will create an xorg file in x11. Add the following to the file and save it. Here's what worked for me. If you modify any other settings in synclient and like them, add them as options to your new file, and they will be implemented on boot.
