Disable the Synaptics touchpad when typing

On my HP laptop there is a button above the touchpad where I can disable and enable it directly in hardware. This button does not exist on my Dell laptop though, so something in software has to do.

If you have followed my guide about fixing the speed on the touchpad earlier, you can skip this step. Otherwise you will have to add the following to your /etc/X11/xorg.conf file under the synaptics input device. Note that quotes are converted by WordPress, so remember to change those to normal ones.

Option “SHMConfig” “on”

Now go to System – Preferences – Session and click New and add make it look like the following image:

That is “syndaemon -i 1 -d”.

If you have added the SHM option, you have to restart X, Logout and press ctrl-alt-backspace. If you just added the session command, just logout and back in or run the command manually.

This will disable the touchpad once you start typing and enable it after one second of typing inactivity.
