Asked by Ed-ekennedy

Touchpad is not working. When I type synclient in terminal I get the following error:
Couldn't find synaptics properties. No synaptics driver loaded?
What can I do to fix this?

Looking at the Xorg.0.log, there is an error that occurs at some point that makes the touchpad not work. The error is:
(EE) SynPS/2 Synaptics TouchPad: Read error 19

After I turn on my laptop everything works. Then randomly out of no where the touchpad stops working. The /var/log/Xorg.0.log looks like something happens to the driver:

Then out of nowhere my touchpad starts to work again. I check the logs and it looks like synaptics is loading and unloading:

My laptop is always in this constant cycle of loading and unloading the touchpad driver. Is there anything else I can provide to help in trobleshooting this bug?

Hi, this looks like a bug to the kernel / driver, please open a bug report with "ubuntu-bug linux" command, you can find some useful debugging technique here from the Wiki page (https://wiki.ubuntu.com/DebuggingTouchpadDetection).
Thanks!

Isn't this laptop sold with Ubuntu on it?
