When I upgraded my netbook from Ubuntu 9.04 to 9.10, I quickly noticed that they had flipped the functionality of 2-finger and 3-finger tapping. I need middle-click (3rd mouse button) functionality far more often than I need right-click, and by default GNOME uses Alt+Middle-Click as a shortcut to resize windows. Doing this with 3 fingers, as well as manipulating links and tabs and dragging objects in my panel is just cumbersome, so I embarked on a Google journey to find out how to swap 2- and 3-finger tap functionality. I found the solution on the Ubuntu Forums.
Just create a script like this:
You can put this anywhere. I called mine
~/bin/swaptaps. Remember to
+x swaptaps. For the best effect, add it as a Startup Application (GNOME menu
→ System → Preferences → Startup Applications).
My testing shows that this works after rebooting as well as after logging in and out. I haven’t tested this with multiple users on the same machine, so if anybody does, please comment and share your results.
Update: Using this as a login script no longer works reliably. I frequently have to run it manually. I’ve tried adding a delay of a few seconds, and it doesn’t seem to help. It’s possible that the default behavior switched back, and my login script is switching it back. I haven’t tested this theory yet. I’ll update if I do.
