HOWTO: Disable the ‘Tap’ Function on my Touchpad?
This is a tricky subject and I’ve had brilliant successes and dismal failures with it. If you have a Synaptics touchpad, you can use the following steps. If you have an ALPS touchpad then I *believe* the same steps will work for you, but I can’t be sure. Synaptics, at least, also has a GUI available to control the touchpad which means you won’t have to go into the command line as I’m about to do.
Sadly, many laptops’ touchpads show up as USB mice (as was the case with my old Inspiron 1000). Since the computer thinks it is a normal mouse, I don’t believe there is any way to pass parameters to it to shut off the tapping.
This procudure, however, has worked on both my current Dell inspiron 9400 and Kelly’s Acer Aspire 3000.
Open a terminal window and open the /etc/X11/xorg.conf file for editing. In Kubuntu:
Press Alt+F2 and type in Konsole
Type sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.original
Type sudo nano /etc/X11/xorg.conf
In Ubuntu:
Press Alt+F2 and type in gnome-terminal
Type sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.original
Type sudo gedit /etc/X11/xorg.conf
Scroll down to the Input Device section and add the following lines:
Option “TapButton0″ “0″
Option “TapButton1″ “0″
Option “TapButton2″ “0″
Different areas of the touchpad mimic mouse buttons. The tap mimicing the left-click is one such beastie. What we’re doing here is shutting them all off. I’m not entirely sure how many TapButtons there are to shut off, but these three ( 0 - 2) seem to turn everything off. If you have a really fancy touchpad, you may require more. I’m sure there’s a much better technical explanation for this, but that’s how I see it :)
Enjoy!
