I have a brand new Sony Vaio S with a big sensitive touchpad that is making it very difficult to type more than a couple lines without accidentally clicking something. I've been scouring the internet for a way to turn off touchpad tap=click this evening and have decided I need to post this here. Some things I've learned already:

First of all, I have installed synaptic (which did not come pre-installed with openSUSE 11.4 interestingly). When I try to run it (or when I click "TouchPad" in Control Center I get the following classic error:

GSynaptics couldn't initialize.
You have to set 'SHMConfig' 'true' in xorg.conf or XF86Config to use GSynaptics

Regarding "/etc/X11/xorg.conf": this file does not exist in openSUSE 11.4. Instead there is "xorg.conf.install" and a directory called "xorg.conf.d" There is a file "50-synaptics.conf" in the directory. Adding:

Option "SHMConfig" "true"

here does not allow me to run synaptics. Being unable to run synaptics, I looked for other ways. A lot of people simply changed their "/etc/X11/xorg.conf" (which again does not exist) to include

Option "MaxTapTime" "0"

I've tried adding this to "/etc/X11/xorg.conf.install" and to "/etc/X11/xorg.conf.d/50-synaptic.conf" to no avail. Which leads to this forum post and me being out of ideas.

Thanks in advance.

Look for the options "TapButton1", "TapButton2" and "TapButton3" in the 50-synaptics.conf-file and change the values to "0". Then reboot. This should disable the tapping.

Those options weren't there in "50-synaptic.conf" I added them though. It didn't work.

For reference, I show you my 50-synaptics.conf:Keep in mind that I have tapping enabled ("TapButton1" "1").

Here's mine, which does not turn off touchpad clicking:
I've also tried reinstalling gsynaptics (which seems to be ignoring this file).

Also of note, I still can't run the synaptics gui (by clicking Touchpad in Control Center). The error is:

As you can see I've tried to set that above. I've tried "true", and "1". My guess is that this is the wrong place. But GSynaptics is asking for the change in xorg.conf, which again, is a file that doesn't exist. I could try to put "SHMConfig" "true" in xorg.conf.install, but I have no idea what section it would go in.

Just go to Personal Settings (Configure Desktop), Hardware, Input Devices. If it's seen as a touchpad and the drivers are properly loaded, there will be a touchpad section with a tapping tab. You can simply disable tapping there.

This thread is discussing that the touchpad tab is not present in the Control Center -> Mouse window. Something is wrong with the the driver and/or gsynaptics.

I have a Sony VPCF11 laptop. I know it's a different model from yours, but maybe it has the same touchpad hardware.

I had major troubles with the touchpad, and wanted to disable tap-to-click.

You should see the thread here for more information, and suggestions for getting it working, or disabling it completely (which is what I did in the end).
