Touchpad and SHMConfig

[bREAk]

Hello forum!

I've been struggling with the following for several hours and now I finally resort to asking here.

I'm trying to make some settings to my synaptics touchpad on an old Comapq Armeda laptop. I'm running Debian with LXDE.
Which ever approach I choose it seems I need to enable SHMConfig. From what I've read all over the internet I have to manually enable it in either xorg.conf or in XF86Config.
The xorg.conf file came out blank after installation and I can't seem to find a XF86Config file (although the "Find Files" doesn't seem to find anything!).
I've tried to add:

Code: Select all

Section "InputDevice"
            Identifier "Synaptics Touchpad"
            Driver "synaptics"
            Option "SHMConfig"    "true"
EndSection

without result. Then I added:

Code: Select all

Option "SendCoreEvents"    "true"

which didn't do any difference. Finally I added:

Code: Select all

Section "ServerLayout"
            InputDevice "touchpad"   "AlwaysCore"
EndSection

Something tells me that the xorg.conf file has become obsolete since it was all empty after install, but I have nothing else to go by.

Cheers,

Obviously, I've missed to load the driver in the module section:

Code: Select all

Section "Module"
            Load "synaptics"
EndSection

Now I wonder if there's a way to configure the size of the scroll zones?
