Ubuntu 11.04 doesn't seem to have an entry for my Synaptics Touchpad xorg.conf file by default.
As soon as I create
Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
EndSection
then GDM fails to start at all.
What is the propery way for me to enter an option for my Synaptics touchpad in xorg.conf?
