Touchpad and keybord not responding after random time of using the touchpad

[Václav Pavlík]

Hi,

I have Ubuntu 14.04.3 LTS (64-bit) on HP Pavilion g6.
When I use the built-in touchpad, after a random time the touchpad stops responding. The keyboard stops working as well. The only thing that would work is the USB mouse, but only when it is plugged in the USB 3.0 port. In other words, it seems to disable all USB 2.0 as well. So I use the mouse to asleep the machine and after the wake-up all is fine, until I use the touchpad again.

The power cord in or out has no effect on it.
I observe this bug since 12.04.

Could anyone help?
Thanks.

I don't know which package is responsible but the problem stays even after kernel upgrade.

Here is more info about my machine.

So, yesterday I installed new kernel, now I am on
Uname: Linux 4.2.0-18-generic #22~14.04.1-Ubuntu SMP Fri Nov 6 22:20:11 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Since then I used my laptop for several hours only with the touchpad and the power cord unplugged (before such configuration led to the freeze the quickest). I also tried to suspend and wake the laptop several times and so far no freezing!

I don't know, however, what in the old kernel might have been causing the problem.
If anybody knows, let me know too.

Thanks.

Well, the freezing is back.

Is there anybody who can help? I have been replying to myself for a whole week.

Thanks.
