Touchpad settings are grayed out

[Sudhir Khanger]

Hi,

Mouse Click Emulation in Taps and horizontal scrolling in Two-finger
scrolling are disabled in SystemSettings>Input on a freshly installed
F22 running on Thinkpad T420i.

Tapping on the touchpad can't emulate right or left click. Horizontal
scrolling is enabled by default and can't be disabled.

How do I gain back the ability to modify these options?
