How does it work in a live boot of 16.04?

[truongkechun]

I did a upgrade one, not fresh install, I upgraded from 15.10.

ah I ran this and problem solved: sudo apt-get install xserver-xorg-input-synaptics

ah I ran this and problem solved: sudo apt-get install xserver-xorg-input-synapticsI upgraded from 14.04 to 16.04 and that program is present without my having to do anything:


09:01 AM ~ $ apt-cache policy xserver-xorg-input-synaptics

Same scenario here, I have updated from ubuntu 14.04 to 16.04 on a Acer V5 and the touch pad stoped working, installing this package worked again, thx.

Upgraded from 15.10 to 16.04 on Dell XPS 13 9343 and found that this was required to enable the touchpad.

Not working suddenly stop working

Exactly the same issue here. Touchpad does NOT work even after having xserver-xorg-input-synaptics reinstalled ...
Is it a hardware problem? -- I'm using GT72-6QE
or a software/OS problem? -- Ubuntu 16.04.1

Cheers

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
