Synaptics touchpad, SHMConfig, xorg.conf and Ubuntu Intrepid 8.10
EDIT – Please note that this post only refers to the 64 bit version of Ubuntu.
Some significant changes have been happening to the X server over the past couple of releases of Ubuntu. One of the most noticeable alterations has been the removal of the xorg.conf file from the default Ubuntu install (edit – it was removed during the development cycle but reappeared in the release version).
It is a great thing that X is now at the stage where it knows devices well enough to configure them with no user input, but occasionally a device may be incorrectly set up, or one may want to customise beyond default settings.
Such is the case with my synaptics touchpad. I really like the fact that in Linux I can configure the touchpad to trigger a middle mouse button event when it is tapped with 3 fingers. Left click – one finger, right click – two fingers, middle click – three fingers. In addition, I want to be able to disable the touchpad while typing.
