Another point: you did look at /var/log/Xorg.0.log?

You ought to find something like:-
-----------------------------------------
(II) config/udev: Adding input device SynPS/2 Synaptics TouchPad (/dev/input/event9)
(**) SynPS/2 Synaptics TouchPad: Applying InputClass "evdev touchpad catchall"
(**) SynPS/2 Synaptics TouchPad: Applying InputClass "touchpad catchall"
(**) SynPS/2 Synaptics TouchPad: Applying InputClass "SynPS/2 Synaptics TouchPad"
(II) LoadModule: "synaptics"
(II) Loading /usr/lib/xorg/modules/input/synaptics_drv.so
(II) Module synaptics: vendor="X.Org Foundation"

(**) Option "RightEdge" "5700"

    [...] snip

Notice the 
(II) LoadModule: "synaptics"
(II) Loading /usr/lib/xorg/modules/input/synaptics_drv.so

If you don't have synaptics_drv.so shown as loaded in the log file,
that is obviously the problem. I would expect xorg.conf to be the
solution unless you have an older system & need fdi or udev entries.
Note above that udev is used: I think that the standard udev system now
supports synaptics, but maybe not for whatever you have on your system.
Anyway, I think you now have enough clues to track it down?


You need to experiment to find out what is happening.

Sorry, well out of time.
