touchpad configuration


Hello!

It seems that I cannot configure my touchpad via xorg.conf. Whatever touchpad related changes I add there, the only effect I have seen so far is X refusing to start, most of the times X starts normally and touchpad works as usual.

The problem is that in Ubuntu I do not have the vertical scroll option, acceleration for touchpad and I also can not turn the touchpad off.

I also have SUSE installed on the same machine and configuring its xorg.conf works perfectly. Also vertical scrolling and acceleration etc. Only when I completely remove everything synaptics related from xorg.conf the touchpad works as in Ubuntu.

I have read most related topics from this forum but can't find the solution.

Andres

Ok, I rephrase my question!

How can I be sure, that the lines in my xorg.conf file concerning synaptic (or ALPS) touchpad actually describe the part of the hardware or in other words, how to be sure that the synaptics driver is actually being used?

Code:
cat /proc/bus/input/devices
give me the following lines:
Code:
I: Bus=0011 Vendor=0002 Product=0008 Version=7321
N: Name="AlpsPS/2 ALPS GlidePoint"
P: Phys=isa0060/serio4/input0
H: Handlers=mouse1 event2 ts1
B: EV=f
B: KEY=420 0 70000 0 0 0 0 0 0 0 0
B: REL=3
B: ABS=1000003
In xorg.conf I have tried several possible values for the
Code:
Option          "Device"        ""
but none seems to have any effect, even the most logical value
Code:
Option          "Device"  "/dev/input/event2"

Ok, the combination of "device" "/dev/input/event2" works together with option "protocol" "event". To completely turn off touchpad, you have to modify also the main mouse from "device" "/dev/input/mice" to "/dev/input/mouse2" or whatever defines your mouse.

To find out, which mouse uses which device, "cat /dev/input/event*" where * is 0,1,2. Moving either mouse or touching keyboard should bring carbage on screen from corresponding device. Though this does not seem to work anymore after synaptics is correctly configured.

ok, I can get things working defining devices like "/dev/input/mouse2" and "/dev/input/event2". But there comes another problem - when I reboot the computer it sometimes redefines the devices, so that touchpad is event0 instead of event2 and usb-mouse is mouse0 instead of mouse2. How could I change my system in a way that every time it boots touchpad is event2 and usbmouse is mouse2. Is it possible at all this way?
