Introduction

Getting your touchpad working properly seems to be a bit tricky with xorg 1.10.2. The control file for your touchpad is called 50-synaptics.conf and is located in the /etc/X11/xorg.conf.d folder. I have set this file up in default mode with the x11-driver-input-synaptics-1.4.1-2pclos2011.i586.rpm package mainly because I'm tired of tinkering with the default config file. Seems if I set in one way it works for some people and not for others. So here are some possible solutions for you. One of these should work for you.

Solution 1 - Use the default mode & configure your touchpad from KDE Configure Your Desktop

  • 1. Open Konsole
  • 2. Type kdesu kwrite (this will open kwrite as su)
  • 3. Copy and paste the following:
#Default Configuration (used by Fedora)
Section "InputClass" Identifier "touchpad catchall" Driver "synaptics" MatchIsTouchpad "on" MatchDevicePath "/dev/input/event*" EndSection
  • 4. Save the file as 50-synaptics.conf in /etc/X11/xorg.conf.d/
  • 5. Reboot.

Solution 2 - Alter the configuration file as shown below

(Used by Opensuse and works for most people)
