My original post described how to install the qsynaptic utility to fix this problem, but it turns out that the settings are lost every time you restart your computer, so I have found a much quicker fix to disable touchpad tapping. Just add this line to your /etc/X11/xorg.conf:
Option "TapButton1" "0"
If I get some time I will re-visit this issue to see why the other method doesn’t save.
Broken Method – Doesn’t Save Settings!
One thing that always frustrates me when I install Ubuntu on a laptop, is that the default behaviour for the touchpad is to allow “tapping” as a left button click. Perhaps it’s just me with my fat fingers, but I am constantly clicking by accident. However, thankfully it is easy to fix with 4 simple steps.
- Simply edit /etc/X11/xorg.conf, find the labelled “Synaptics Touchpad” and add the following line to the end of that section:
Option "SHMConfig" "on"
- Install the qsnaptics utility with
sudo apt-get install qsynaptics
- Now you need to load these new settings by rebooting x windows. To do this press CTRL + ALT + BACKSPACE simultaneously.
- Finally, when you have logged back in, press ALT + F2 to bring up the run window. In this type qsynaptics and then click run. This will load qsynaptics where you can disable tapping on the tapping tab.
