Red Hat Bugzilla – Bug 1292583
kernel-4.2.7 clickpad click not working since update to 4.2.7
Last modified: 2016-01-04 04:44:58 EST
Description of problem:
Since updating to 4.2.7 the click function of my touchpad works really bad. Clicks are not recognized. 'Click+keep pressing' to move windows also doesn't work which makes my touchpad useless. Note that tapping still works.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. click with touchpad
click event, like focus window.
This is on Dell XPS 13 9333, I suspect this be caused by this patch, introduced in 4.2.7:
The patch is introduced in bug #1287819
Sigh, I was sure this patch would not have this kind of side effects.
I have asked the question upstream, but it would be interesting to also check the raw data before deciding what to do with the patch:
Could you attach a hid-recorder output of your touchpad while doing:
- single finger move (and click)
- then 2 fingers move (please drop fingers 1, 2 and then release 1, 2 in the same order, this catches bugs sometimes)
- for fun, put as many fingers as you can :)

I'm confused this was 100% reproducible yesterday (rebooted multiple times between 4.2.6 and 4.2.7) but today it just works as expected.
I'm still having this issue bug #1250213 but don't expect it is related.
Piotr, I'd like to close this bug if you still can't reproduce it. Could you confirm this?
I still cannot reproduce it anymore. This can be closed.
I really have no clue why this did happen before...
Thanks for the quick test.
