Ubuntu 16.04 touchpad not working

[mörgæs]

You could try a live boot of 16.10 (daily build of the development version) for comparison.

Hi there,
I'm also having this issue with a brand new kubuntu 16.04. The touchpad of my Asus k501UW is working just as a regular mouse but no multitouch. I tried to ```apt-get install xserver-xorg-input-synaptics``` and it told me that it was already installed. accessing system settings -> input devices -> touchpad and I get a message saying "Synaptics backend not found"
any suggestions?
Thanks in advance

I think this is the actual "state of the art" with this on Asus laptops and it should be referenced for others to follow

Here is something that fixed touchpad issues for me on some HP Stream laptops with Lubuntu 14, 15, and 16 versions.
1. create a new directory in /etc/X11/ called xorg.conf.d

  sudo mkdir /etc/X11/xorg.conf.d

2. Copy the Synatptics config file from /usr/share/X11/xorg.conf.d to the new directory -file will probably start with 20- or 50 -synaptics.conf

   sudo cp 50-synaptics.conf /etc/X11/xorg.conf

3. Now go to the new directory and Edit the file to add two lines in the first "Input Class" section

   cd /etc/X11/xorg.conf.d
             sudo nano 50-synaptics.conf

under the line saying "MatchDevicePath "/dev/input/event" in the first "InputClass" section, insert these two lines:

    # Enable ClickPad to fix drag/drop on some laptop models
     Option    "ClickPad"   "1"

4. Save and Exit editor
Ctrl+O Enter to confirm Ctrl+X
5. Reboot

Now your Touchpad should support dragging and dropping

Hello,

I think it's possible to be a simple configuration problem. I had same problem with touchpad scroll on ubuntu 16.04 and Acer Aspire 5750 and I solved problem with "System Settings" -> "Mouse & Touchpad" and unchecked "Two finger scroll". Hope to helped.

This worked for me on my alienware15

sudo su
echo 'blacklist i2c_hid' >> /etc/modprobe.d/blacklist.conf
depmod -a
update-initramfs -u
