Hi,

I have a Fedora laptop with a vertical and horizontal scroll section. The horizontal scroll has never worked, and only occasionally on Windows XP. I rediscovered KDE 4 on Fedora 11 while doing technical support over a phone for a friend of mine, and I discovered the scroll section didn't work. After a while, I realised that for some reason, KDE 4 had decided to spontaneously switch to using multi-touch for scrolling.

I switched back to the default environment (GNOME) after some issues with Konsoles not accepting input, etc., and found that multi-touch had gone away.

I'd like to know how KDE switched to multitouch on my system.

Thanks.

What kind of touchpad is it? (My guess is Synaptics). Do you use GSynaptics or something like that?

Am using Fedora 11 myself and I can tell you that it's not a part of KDE that it supported multitouch. They only updated synaptics to a recent version.

If GSynaptics doesn't work as expected try synclient which is a console tool and is probably already installed on your system.

Try "synclient -l" to see what's possible. synclient changes only the settings of the current session (so no problem if something breaks). To change it for all times you have to modify "/usr/share/hal/fdi/policy/20thirdparty/10-synaptics.fdi".

FWIW - I have a Synaptics touchpad and the only way I've been able to get custom options to work to use snyclient. I have tried HAL .fdi and I tried gsynaptics but neither worked.

Once I worked out in synclient, what commands did what I wanted, I made a little shell script to run in 'Autostart' and viola - I am happy.

FYI here's my script

#!/bin/bash

synclient LTCornerButton=2
synclient LBCornerButton=3
synclient TapButton1=1


This lets me use a tap on the touchpad for Left Click; tap on the Left Upper Corner of the touchpad for Middle Click and tap on the Left Lower Corner of the touchpad for Right Click. There are many more options possible.

The HAL/.fdi stuff worked with me. But if it work's

And you probably don't have the problem when updating your system (synaptic) that all the settings made vanish.
