Most touchpad options greyed out?! - KDE5

For some reason, my touchpad options are now greyed out. I do not know when this began. All the options used to be available to me.

My touchpad works and is clearly detected:

kcm-touchpad-list-devices
Name: Virtual core pointer Type: unknown Use: Pointer
Name: Virtual core keyboard Type: unknown Use: Keyboard
Name: Virtual core XTEST pointer Type: unknown Use: Extension Pointer
Name: Virtual core XTEST keyboard Type: unknown Use: Extension Keyboard
Name: Power Button Type: KEYBOARD Use: Extension Keyboard
Name: Video Bus Type: KEYBOARD Use: Extension Keyboard
Name: Power Button Type: KEYBOARD Use: Extension Keyboard
Name: Sleep Button Type: KEYBOARD Use: Extension Keyboard
Name: Chicony USB 2.0 Camera Type: KEYBOARD Use: Extension Keyboard
Name: AT Translated Set 2 keyboard Type: KEYBOARD Use: Extension Keyboard
Name: SynPS/2 Synaptics TouchPad Type: TOUCHPAD Use: Extension Pointer

installing xf86-input-synaptics has no effect.

Any thoughts or ideas would be much appreciated.

I don't use KDE or any such gui tools, but the checkbox to activate the emulation isn't greyed out is it?  It stands to reason that all those other settings depend on that one - so check the box to turn on emulation and see if the other settings are then accessible.

If you have xf86-input-libinput installed it will take control of the touchpad by default. The libinput driver exposes fewer options than the synaptics one, so they will be disabled in the gui

That would be the obvious answer, yes. However selecting that checkbox 'ungreys' just the labels on the (some of) other options. Not the options themselves:

Possibly a bug. I will probably report this upstream if I don't figure it out soon.

pacman -Ss xf86-input-libinput
extra/xf86-input-libinput 0.11.0-1 (xorg-drivers xorg) [installed]
    Generic input driver for the X.Org server based on libinput

It is installed. Has been the whole time. Reinstalling doesn't help

Thanks

You misunderstood, this is exactly the issue. libinput offers very few options, if you want all the options you have to uninstall libinput so that synaptics is used.
