I dont know how to change the status my bug report. What I did was
switch to my windows partition and boot there. The touchpad worked and
now I switched back to linux and it suddenly worked.

I dont know what really happened but that fixed it for me...
I rebooted multiple times to apply the package or driver changes, so that can 
not be it in my opinion.

Title:
  Touchpad not working

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I installed ubuntu 2 months ago and everything was fine until
  yesterday. I shutdown my system and when i booted my laptop, the
  touchpad didnt work. I tried some possible solutions by uninstalling
  the xserver-xorg package but that didnt help either.

  The touchpad is not being detected when I list the xinput. So I read
  that I should file a bug report because that might be a kernel bug or
  soomething.
