  • What is the laptop model? What is the kernel version uname -a. Please edit your question and add this information TO YOUR QUESTION. – Pilot6 Nov 27 '15 at 8:56
  • You added only kernel version? What is your laptop model? – Pilot6 Nov 27 '15 at 9:21

Most likely support of your touchpad has been added to new linux kernels. You can update the kernel by running in terminal:

sudo apt-get install linux-generic-lts-wily

Then reboot and try the touchpad.

  • still not working .now my kernel version shows as Linux nithya-Satellite-C850 4.2.0-18-generic #22~14.04.1-Ubuntu SMP Fri Nov 6 22:20:11 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux @Pilot6 – User5 Nov 27 '15 at 10:29
  • The touchpad is probably not supported yet. – Pilot6 Nov 27 '15 at 10:52
  • can you give any other suggestions? – User5 Nov 28 '15 at 8:21
  • In this case I would report a bug, or program a kernel fix. There is no easy solution I am afraid. – Pilot6 Nov 28 '15 at 8:28
  • now my touchpad works – User5 Nov 29 '15 at 8:26
