Thank you for replying. I tried what you posted and it did fail. So, I checked the bug report and changed the end of the script to avoid this error.
property Synaptics Right Button Area doesn't exist, you need to specify its type
And this is what happened.
I'm not sure what any of that means. The repeated use of failed doesn't look good though.
~/Downloads$ ./enable-rightbutton.sh 13
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 141 (XInputExtension)
Minor opcode of failed request: 57 ()

Current serial number in output stream: 21
Tapping the lower right corner for right click is pretty cool but I can't seem to hit it very often. The success rate is pretty similar to the 2 finger tap.
