Disable Synaptics Touchpad while Typing

Laptop touchpads get in the way of typing quite often and can actually cause accidental highligh and deletion when such a thing is not intended. This workaround inserts a small delay in the response of the touchpad after typing:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
sudo vi /etc/X11/xorg.conf

Into the "Synaptics Touchpad" section insert the following:

Option "SHMConfig" "on"

Start the syndaemon automatically during startup: Open System -> Preferences -> Sessions and add the following:

syndaemon -i 1 -d

Finally restart Gnome.
