Retire Synaptics Driver
[package]*xorg-x11-drv-synaptics* has been the main X.Org touchpad driver for over a decade. Since Fedora 22, it has been superseded by [package]*xorg-x11-drv-libinput* which aims to provide a better touchpad experience.
Starting with Fedora 26:
a fresh installation of Fedora will install [package]*xorg-x11-drv-libinput* instead of [package]*xorg-x11-drv-synaptics*;
an upgrade from an earlier Fedora will install [package]*xorg-x11-drv-libinput* and remove [package]*xorg-x11-drv-synaptics*;
users that need the synaptics driver will need to manually install [package]*xorg-x11-drv-synaptics-legacy*, which will install the synaptics driver and give it precedence over the *libinput* driver;
removing [package]*xorg-x11-drv-synaptics-legacy* will remove the synaptics driver and the system will automatically revert to the *libinput* driver.
