Ubuntu – Missing mouse/touchpad options (Ubuntu 16.04)

mousesynapticstouchpad

It seems I've lost some of my mouse and touchpad settings:

As it is, I can move the pointer with the touchpad, but there's no tap-to-click and it's set to non-natural two-finger scrolling.

So far, I've tried uninstalling/installing Synaptics touchpad driver, but no luck with that.

Does anyone know how can I get scrolling and click options back?

Best Answer

Alright, so I found a solution to my issue here, but here's a more concise explanation of what actually solved my issue:

Basically, I had to go to /usr/shar/X11/xorg.conf.d and edit the 50-synaptics.conf file. Assuming root privileges, I opened this file in nano and added the following three lines under the third stanza, right below any already-listed Option:

Option "VertEdgeScroll" "1"
Option "TapButton2" "2"
Option "TapButton3" "3"

I then saved this as 90-synaptics.conf and removed any competing libinput files. Rebooted, and got back tap-to-click, two-fingered right click, and edge scrolling (both vertical AND horizontal); exactly the same setup I had before.

From the Mouse and Touchpad settings menu, I regained everything but the ability to turn on/off horizontal scrolling.

You can fix it this way:

sudo -H gedit /etc/default/grub

In the open window edit line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

it should look this way

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nopnp"

Save file and run

sudo update-grub

Run

echo "blacklist i2c_hid" | sudo tee /etc/modprobe.d/i2c-hid.conf
sudo depmod -a
sudo update-initramfs -u
echo "synaptics_i2c" | sudo tee -a /etc/modules

Reboot.

Please be careful, do not retype these commands, but copy them and paste into the terminal, or you can break the whole system, if mistype.

This solution disables Plug & Play for i8042 devices, then disables i2c-hid module and enables synaptics_i2c instead or it.

Plug & Play triggers a wrong module for this device.

Ubuntu – Touchpad tap stopped working

It looks like you installed libinput. You have two options:

Enable tapping with libinput. It can be done by adding
```
Option "Tapping" "true"
```

to the touchpad section of /usr/share/X11/xorg.conf.d/90-libinput.conf.

Tapping in libinput is disabled by defualt.

Remove libinput. That will revert to xorg-synaptics user space driver. It can be done by
```
sudo apt remove xserver-xorg-input-libinput
```

libinput is a new user space driver that will replace xorg-synaptics in new distro versions. I do not recommend to remove it.
