GNOME Bugzilla – Bug 748647
"Touchpad" section disappears from "Mouse & Touchpad" screen when disabling the touchpad

The moment I pressed on the touchpad on/off toggle the whole "Touchpad" section disappeared, making it impossible to re-enable the touchpad.
You can re-enable your touchpad e.g. by: gsettings set org.gnome.desktop.peripherals.touchpad send-events enabled *** This bug has been marked as a duplicate of bug 747502 ***
