Scope

openSUSE tries to make various desktop environments available to its users. Since openSUSE 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.

Please note that this is only a resource to aid our users. For discussions on this setting, please talk to the relevant DE upstream. openSUSE does not intend to make any changes to upstream defaults.
