Feedback on the HP 350 G2 Notebook PC - Snowman

Asked by Ed-ekennedy on 2015-07-10

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?

Hi,
which version of Ubuntu you're using? Is your computer pre-installed with Ubuntu?
Thanks

Currently using 15.04. Also had 14.04 with the same isssues. The laptop was not preinstalled with Ubuntu.

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:

Ed-ekennedy (ed-ekennedy) said : #6

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?

Po-Hsu Lin (cypressyew) said : #7

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!
FAQ #2193: “XXXX is broken, I need to file a bug”.

Ed-ekennedy (ed-ekennedy) said : #8

Isn't this laptop sold with Ubuntu on it?

Po-Hsu Lin (cypressyew) said : #9

Hi,
yes, for the difference, please check this article:

Cheers.

Can you help with this problem?
