mouse and touchpad settings missing

It is possible to get back the touchpad and mouse settings in your control panel.

You can simply install it either from synaptic package manager or by using the following apt command

sudo apt-get install touchpad-indicator

If you are facing the problem with the settings just remove the mouse and touchpad settings file by the following command

rm -fr ~/.gconf/desktop/gnome/peripherals/mouse

Hope this will help you better to resolve your issues.

I think it depends on how your touchpad is recognized - it looks the same with my HP Envy x360 15'. You will have more GUI options with gpointing-device-settings or Touchpad-indicator.
