Ubuntu 16.04: The settings menu used to have separate settings for external mouse and touchpad, now it only contains one set of settings for both. The settings for pointer speed actually do not change any behavior of the mouse – the mouse motion doesn't change regardless the change in the speed setting.
This is what my settings look like after mouse & touchpad settings broke:
It looks like this might have been an issue before… mouse and touchpad settings missing
…but I am running 16.04, not 14.04. There is no touchpad-indicator program by default, and when adding the repository listed in one of the answers, it didn't help anything.
This may also be related to ELAN touchpad suddenly stopped working, worked the day before, but I do not have nearly as many problems as that person is having:
The touchpad works, it is at an okay speed, I can scroll with two-fingers, but these are all settings I set before Settings broke like this. I can no longer change the speed, disable two-finger scrolling, or anything like that. No mouse settings, except for double-click speed and primary button work.
Again, this is what it is supposed to look like (something close to it). This is what it did look like, but now it looks like the one above.
I know an issue like this is a known bug: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1132063, but this recently happened. That bug has been an issue for a while it seems, and my machine (originally 14.04) has been through updates and new releases, and it only recently broke after an update. As well, I have a basic "Mouse: Pointer Speed" setting in mine that isn't present in the bug report screenshots.
Any way to fix this?

So now all settings are working except for the touchpad speed.
Best Answer
You have installed
libinput. It is used instead ofxorg-synapticsto manage the touchpad.Unfortunately current Ubuntu with Unity DE does not have
libinputsettings GUI by default.unity-control-centercan control only ofxorg-synapics.Another option is to uninstall
xserver-xorg-input-libinputpackage and usexserver-xorg-input-synapticsthat is installed by default instead.
