I noticed that the Fedora Linux with KDE desktop, has reasonably poor support for laptop touchpad adjustment. For example, the KDE > System Settings > Keyboard & Mouse > Mouse options will not be able to enable vertical scrolling and touchpad tapping. So I decided to write this short guide, howto enable Touchpad vertical scrolling and tapping from command line without any GUI.

Enable Laptop Touchpad Vertical Scrolling⌗

Simply write following on command line:

synclient VertEdgeScroll=1

Enable Laptop Touchpad Tapping⌗

Simply write following on command line:

synclient TapButton1=1

Make Previous Options Permanent⌗

Change to root User

su -
## OR ##
sudo -i

Create a configuration file
Copy /usr/share/hal/fdi/policies/20thirdparty/10-synaptics.fdi example file to /etc/hal/fdi/policy

cp /usr/share/hal/fdi/policy/20thirdparty/10-synaptics.fdi /etc/hal/fdi/policy

Add following lines to configuration file

<merge key="input.x11_options.VertEdgeScroll" type="string">1</merge>
<merge key="input.x11_options.TapButton1" type="string">1</merge>

Full configuration file looks like this

<?xml version="1.0" encoding="ISO-8859-1"??>
<deviceinfo version="0.2">

    <match contains="input.touchpad" key="info.capabilities">

        <merge key="input.x11_options.VertEdgeScroll" type="string">1</merge>
        <merge key="input.x11_options.TapButton1" type="string">1</merge>
    </match>
