http://askubuntu.com – I just installed Ubuntu 11.10 on my MacBook Pro, and I have enabled two-finger scroll. Now I'm unable to move a window with the trackpad, which is usually done by click-and-holding the window title (with one finger) and dragging (with another finger). How do I move a window without disabling the two-finger scroll? (HowTos)
