Touchpad problems?


To change the behavior of the Synaptics/Alps touch pad, use Control Panel - Desktop - Adjust Touch Pad. If Adjust Touch Pad errors when you launch it, your touch pad is probably not supported yet. For Dell 13z and others there is another touch pad driver included. To use it, open the Control Panel and click on the  System tab. Then click on Manage Servers and Services, and then Dell-psmouse. Click Start to start using this driver now and Enable to use this driver at every boot. Then restart the X server.

If
Control Panel - Desktop - Adjust Touch Pad doesn't offer the option you want to adjust, you can do it manually by editing /usr/X11R7/lib64/X11/xorg.conf.d/50-synaptics.conf. By default that file contains this:
Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
            Option "TapButton1" "1"
            Option "TapButton2" "2"
            Option "TapButton3" "3"
            Option  "MaxTapTime" "0"
 EndSection

After editing this file you must restart the X server for changes to take effect.

Here’s a couple popular options to adjust :

By default "tap-to-click" is disabled as some touchpads are overly sensitive, making the system impossible to use if it is left on. To turn it back on:

  1. Open Adjust Touchpad control from within Control Panel (under Desktop tab)
  2. Go to the "tapping" tab
  3. Use the "One Finger" pull down menu to select "left button".
  4. Then click save and quit.

To enable vertical scrolling, open Adjust Touchpad as above, then go to "Scrolling" tab and check "Vertical Edge Scroll" and uncheck all the others.

If you need other configuration options take a look at the man page for Synaptics.
