I installed Ubuntu 15.04 and then upgraded to Ubuntu 15.10 on my laptop (Fujitsu U745). My touchpad works in Windows but never worked in both versions of Ubuntu.

It shows up in xinput list command

    xinput list
    ⎡ Virtual core pointer                      id=2    [master pointer  (3)]

    ↳ AT Translated Set 2 keyboard              id=12   [slave  keyboard (3)]

But in dconf-editor it isn't even listed

No touchpad option listed

Looking around the web rather lead me to nowhere without this listed. Also the mousepad doesn't even work on login screen too and I have checked the Fn-F4 mouse lock.

Update

The Terminal result from the wordpress

  • Do you get any output when you run synclient? – DK Bose Oct 25 '15 at 17:57
  • Yes I do. It just shows the Parameter Settings – Keinden Oct 25 '15 at 18:20
  • Do you have a line with TouchpadOff? – DK Bose Oct 26 '15 at 02:12
  • See if http://askubuntu.com/questions/519747/elantech-touchpad-multi-touch-is-not-working-for-kernel-3-13-0-35-generic helps Have you googled for "elantech touchpad linux"? – DK Bose Oct 26 '15 at 05:19
  • Also https://hardc0l2e.wordpress.com/2014/12/06/fix-for-elantech-touchpad-on-ubuntu-14-04/ – DK Bose Oct 26 '15 at 05:22
  • I have googled around and I do remember inputting a command to change 'TouchpadOff' status however it threw me an error as its not an option is the dconf-editor as stated. I'll reply if the link you sent works. – Keinden Oct 26 '15 at 19:03
  • I got an error. It says "Error! Bad return status for module build on kernel: 4.2.0-16-generic (x86_64)". The log will be in the under "Updates". – Keinden Oct 26 '15 at 19:36
  • That dkms module is incompatible with kernel 4.2. – Pilot6 Oct 26 '15 at 19:49

ELAN Touchpad?!? Well ...

„DesignWare“ Touchpad shows similar issues
easy to fix mostly

You may try "modprobe i2c_hid_acpi". This Tip comes from the Fujitsu Laptop community. Make it a systemd service if t works.
update:
currently it's
i2c-hid or i2c-hid-acpi
watch out for the spelling and what is applicable on your system

Actually my Fujitsu E 5511 Lifebook needs this help only for touchpad.
Works fine now.
Tested with Ubuntu 22.04beta and 20.04.4LTS.

My older E5510 needed "modprobe i2c_hid" to do anything with input.
Make it a systemd service if it works.
