touchpad stops working (moving the pointer doesn't work)

[Ivan Zakharyaschev]

I'm reporting here the same issue as https://bugs.launchpad.net/ubuntu/+source/linux-ac100/+bug/1035208/ -- I can't tell whether it's a linux driver bug or X.org driver bug.

When I'm reporting this now, my touchpad works (moves the pointer), so the logs might not be that interesting as on the other report (at that moment, I really had the issue).

Because it only partially stops to produce the reaction (no movements, but scrolling), I thought it might be a higher level bug.

It also looks very similar to the description of https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/830099 .

The touchpad must be called Elantech, it's in a Toshiba AC100 (ARM).

Right now this happened once again for me; I've written about it at https://bugs.launchpad.net/xserver-xorg-input-synaptics/+bug/1035208/comments/11 .

BTW, I've found a workaround: put the system into standby mode, and upon the wakeup, the touchpad is fully working again.

Please tell me:

What to do further to diagnose the source of the error?

Hello Ivan,
Could you please upgrade to a newer release and check if problem still present.
Thanks.
