A couple of tips:
1. Check that the synaptics driver
(/usr/lib/xorg/modules/input/synaptics_drv.so) is executable, (ie. -rwxr-xr-x)
nb. use "chmod 755" to make executable
2. "cat /proc/bus/input/devices" should, in part, give the output as
follows...
I: Bus=0011 Vendor=0002 Product=0007 Version=12b1
N: Name="SynPS/2 Synaptics TouchPad"
P: Phys=isa0060/serio4/input0
S: Sysfs=/class/input/input4
U: Uniq=
H: Handlers=mouse0 event4
B: EV=b
B: KEY=6420 0 7000f 0 0 0 0 0 0 0 0
If the Name is "PS/2 Synaptics TouchPad" and not "SynPS2 Synaptics
TouchPad" the driver has not been properly loaded.
This happens when the standard "psmouse" module is loaded first, by
default, before the synaptics driver.
One solution is to comment out the lines that load psmouse in the rc.modules
file.
The relevant lines will then look like this...
# if echo $SHORTREL | grep -qvw 2.4 ; then
# /sbin/modprobe psmouse proto=imps
# fi
Use a rc script (eg. rc.local) to load the "psmouse" kernel module later
in the boot process or after booting, using the command...
modprobe psmouse
The SynPS/2 SYnaptics Touchpad driver should then be correctly
recognised and loaded.
