mouse cursor jumps and clicks randomly after standby

Getting your soundcard to work, using Debian on non-i386 hardware, etc

mouse cursor jumps and clicks randomly after standby

Postby chris+ » 2017-02-06 16:03

I'm using debian quite for a while on a Lenovo Thinkpad Yoga. I started with Debian stable (Jessie) and switched now to testing, but in both versions I can see the same behaviour:
Problem:
  • When I boot the the laptop, everything works fine and I can work for hours and hours.
  • After standby and waking up often everything works fine again, but after several times using standby and waking up it can happen that the mouse cursor suddenly starts moving and clicking randomly. Often it starts slowly and is getting worse when I try to use the touchpad.
Temporary solution:
  • By Typing the following code the mouse cursor stops moving randomly and I can go on working with a bluetooth-mouse:
    Code: Select all
    rmmod psmouse
  • A shutdown and booting again always solves the problem - until using standby several times.
Any ideas to solve the problem? Which information do you need? I can also write a bug report but I'm not sure which package or module is the really responsible for this.
Regards,
Chris

maybe something along these lines will fix it?

or maybe just blacklist psmouse module altogether if it's not needed?

Thank you very much for your reply.
At first I checked my parameter psmouse.resetafter:
Code: Select all
$ cat /sys/module/psmouse/parameters/resetafter
5

Obviously it is already set and didn't helped (as Jeff Hunter also said in the article you linked).

So I forced psmouse to the basic mode with this line in /etc/modprobe.d/psmouse.conf:
Code: Select all
options psmouse proto=bare

Manually this works but it did not used this parameter automatically at boot time. So to solve this quick'n'dirty I reloaded the modul at boot time with this lines in /etc/rc.local:
Code: Select all
modprobe -r psmouse
modprobe psmouse

Now my touchpad is always using the basic protocol. As I said, it always takes several days of standby and waking up so we'll see if the mouse stays friendly.

Thanks again!

I monitored it a while and after a month I can say that this does not solve the problem. Even with proto=bare sometimes the mouse starts moving without touching the touchpad.

At the moment, the laptop isn't able to standby by the way. Maybe it is because of the testing-version of Debian. Maybe this is solved with the next update - but maybe I should write a bug report. I'm not sure...
