Automatically install a Touchpad config gui on laptops.

While touchpads are detected and configured during installation in gutsy, gui configuration tools like gsynaptics etc have to be installed by the user and xorg.conf has to be edited manually to add the SHMConfig = True option. In Hardy, an appropriate gui for the hardware could be installed automatically at installation and the SHMConfig = True option added to xorg.conf when - and only when - the hardware is detected. For Synaptics touchpads, gsynaptics, qsynaptics and ksynaptics are already in the repositories or a new gui could be developed as a front-end for a range of touchpad types. The user should be able to easily specify cursor speed, scroll options, touchpad sensitivity, button emulation (multi-tapping) and delay after typing.
