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: enter image description here

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.

enter image description here

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.

WARNING: Following these instructions blindly may damage your system and require you to do an install from scratch. **Read the entirety of the answer and pay attention to all statements and caveats before attempting any commands or actions recommended in this answer.

You have installed libinput. It is used instead of xorg-synaptics to manage the touchpad.

Unfortunately current Ubuntu with Unity DE does not have libinput settings GUI by default. unity-control-center can control only of xorg-synapics.

Another option is to uninstall xserver-xorg-input-libinput package and use xserver-xorg-input-synaptics that is installed by default instead.

    Looks like libinput was installed automatically with an update. If I try to remove it, tons of packages come up to remove, so I cannot remove it. I installed gnome-control-center and ran it as you showed, and the mouse and touchpad options come up, but they do not actually change the values. I can even "turn off the touchpad" and it will still work. The speed sliders have no effect on the speed of the mouse. Can I make xorg-synaptics be used as the input manager instead? – AlwaysTalkingAboutMyDog Jun 07 '16 at 02:03
  • Are you using Ubuntu, or some other derivative? On my 16.04 xserver-xorg-input-libinput was not installed by default and does not remove any packages. Also libinput is worth keeping. It is good. You can conrol the touchpad using CLI. – Pilot6 Jun 07 '16 at 02:07
  • Ah okay so there fixes one of my problems. I removed the xserver-xorg-input-libinput package, and my settings menu and my xinput output changed (I'll update the question in a second). The mouse speed is now working (which is huge), but the touchpad speed settings still have no effect on the actual touchpad speed. I can disable the touchpad now - it's just the speed that doesn't work. – AlwaysTalkingAboutMyDog Jun 07 '16 at 02:18
  • You got the menu back for me, which was my original issue. Should I now open another question about the touchpad speed not working? or is it still related to this issue? – AlwaysTalkingAboutMyDog Jun 07 '16 at 02:24
  • Touchpad speed does not work for all touchpads. – Pilot6 Jun 07 '16 at 04:07
  • Okay, I'll look that up separately. Thanks for all your help! – AlwaysTalkingAboutMyDog Jun 07 '16 at 04:25
  • This seems to be in conflict with Gnome Shell. Unity seems to need libinput not installed, and Gnome Shell has the exact same problem unless it is installed – nafg Feb 26 '17 at 03:58
  • Warning: I uninstalled xserver-xorg-input-libinput and all all my pointer devices and keyboards stopped working! – Andrew Mao Dec 19 '17 at 06:47
  • @AndrewMao You need to install the other package before restarting.. If your devices have stopped, you need to go to the terminal in recovery mode, and install the new packages – Harsha Dec 31 '19 at 14:19
  • This advice is hazardous! I installed xserver-xorg-input-synaptics and then removed xserver-xorg-input-libinput, and nothing works. Even an external mouse and keyboard does not work. I can't even use keyboard navigation in the grub menu! How do I rescue this? – MRule Oct 04 '21 at 07:28
  • Update: even if synaptics is installed before removing libinput, this advice is still hazardous. If one is not aware that removing/reinstalling synaptics will brick the system (or later forgets that that libinput has been removed), then for example following this advice (https://askubuntu.com/a/1235083/89062) to "fix" the trackpad will effectively brick the laptop. – MRule Oct 04 '21 at 08:26

On my Lenovo Thinkpad L380 Yoga, I was having a similar issue on Pop!_OS 19.04 when I installed Unity. I had to install the xserver-xorg-input-synaptics package, and then the settings showed up.

  • I'm on Pop!_OS 20.10 and had the same issue when I installed Unity, and installing xserver-xorg-input-synaptics fixed it! Note that I had to reboot before it worked. – MalcolmOcean Dec 31 '20 at 07:59

DO NOT UNINSTALL xserver-xorg-input-libinput

Especially when You are on notebook, dont have wired connection (LAN cable) and don't have any other computer.

Your keyboard and mouse will stop working. You will not be able to login to Your PC, You will not be able to launch terminal.

All You can do, is to download xserver-xorg-input-libinput and xserver-xorg-input-all on some other machine, put them on USB drive and install them manually from recovery mode.

  • download xserver-xorg-input-libinput and xserver-xorg-input-libinput two times the same? – derHugo Dec 21 '17 at 06:19
  • In this problem, however, I had another input service. If you don't have the same exact problems that I did, then don't follow the accepted solution.

    And repairing a broken system like that is not at all hard. Just boot into single user mode and reinstall using one of the tty's. Not even a LiveCD is needed to fix that.

     – AlwaysTalkingAboutMyDog Dec 22 '17 at 02:58
  • Corrected packages names, thanks. Also You may be concerned about this, if You are on Ubuntu (mine is 17.10) and other distros relying on libinput as default driver. – Ivan Nikolaev Dec 22 '17 at 13:30

    I wish this answer had been at the top. I followed /u/Pilot6's answer and now have a broken, unusable laptop that I need to spend the day recovering. IMO /u/Pilot6 should be considered hazardous and needs to be revised with appropriate instructions and warnings. I have flagged it as such. – MRule Oct 04 '21 at 07:35
