So I read the other answer for this question but I really was hoping to get a more basic explanation that would make sense to an ubuntu novice.
I am running 12.10 on a 2011 macbook air and love it generally but three finger drag activating whenever I try to re-size a window is driving me completely insane. There seems to be a way to disable it, How can I disable the multitouch gestures in Ubuntu? but I lost the last contributor's advice at "...create a shell script" and the other answers didn't seem to work.
wrt my familiarity with the command line I understand generally how to add repositories and update installed packages. Kind of. That's about it.
Any help for a noob here would be greatly appreciated.
