In Fedora 11, default mouse settings (with regards to laptop and notebook touchpads) have been slightly changed. In previous versions of Fedora, tapping the touchpad to “click” and scrolling using the edge of touchpads was enabled by default. In Fedora 11, these options are now disabled by default. To re-enable these options:

1. Open the Mouse Preferences dialog either by choosing  System > Preferences > Mouse from the Fedora Main Menu or by running the following command from a terminal:

gnome-mouse-properties

2. In the Mouse Preferences dialog, choose the Touchpad tab, and enable the options you desire.
