I have a Lenovo z570 where I installed elementary OS. I installed Synaptic driver from X.org and the dependencies. After a reboot, I completely lost the ability to use my trackpad. Sometimes the physical buttons work, but no movement at all.

I would love to roll back to before I installed the driver when I had functionality.

  • What exactly did you installed? (and how?) What was the reason to install synaptic touch pad drivers if they were already working? – morningbird Sep 4 '15 at 17:22
  • The main reason I was installing it was to try and get the scrolling feature I had in windows on the right hand side of the trackpad. I would drag my finger along the right side along the y-axis and whatever was selected would scroll. When I installed the driver, I read about two finger scrolling instead. Once the touchpad stopped working I realized that all the functionality I was enjoying before (two finger scrolling specifically) was after I had installed the driver, but before a reboot. Then I reasoned that it was already there, I had just not tried it before. – Wetz Sep 4 '15 at 17:37

OK, I followed the instructions here to reinstall the kernel and it is working great. I messed up installing the drivers from xorg and should not have as the functionality was already built into the kernel, I was just not understanding how! Thanks for all who read my question and were trying to help!
