Scope
Fedora tries to make various desktop environments available to its users. Since Fedora tries to stay as close to upstream as possible, we follow the various defaults selected by the desktop environment upstreams. Generally, this entails a disabled touchpad click by default. This wiki page tries to compile the different methods that can be used to enable "tapping" on various desktop environments.
Desktop configurations
GNOME
The "mouse and touchpad" utility can be used to enable tapping and set scrolling options in GNOME.
KDE
LXDE
