Samsung NC10 Touchpad sensitivity

One of the things left outstanding after my Ubuntu installation (see below) was the fact that the touchpad does not work too well, though you could probably get used to it. Moving right/left seems OK, but up/down is rather fast and difficult to control I found. Worse, there is no means of adjusting trackpad sensitivity, so you definitely feel it is second rate compared to Windows and that will never do!

It's back to the Terminal to improve things. Type

gksudo gedit /etc/X11/xorg.conf

This gets you editing a system file called xorg.conf, so it's probably a good idea to back up the original somewhere in case things go horribly wrong. Now add a section as follows:

Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "HorizEdgeScroll" "0"
Option "SHMConfig" "on"
Option "MinSpeed" "0.1"
Option "MaxSpeed" "0.2"
Option "AccelFactor" "0.001"

and save the file. After a restart, you should find the touchpad significantly improved with even movement left/right and up/down.

All credit goes to a chap called “mac” on the “Ubuntu on the Samsung NC10” forum for this. He also guided me through installing and trying to launch a Touchpad applet, but we had to give this up in the end. If you are interested, the thread is here:
