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): 4.2.7-300 How reproducible: always Steps to Reproduce: 1. click with touchpad 2. 3. Actual results: nothing happens. Expected results: click event, like focus window. Additional info: This is on Dell XPS 13 9333, I suspect this be caused by this patch, introduced in 4.2.7: HID-multitouch-enable-palm-rejection-if-device-imple.patch
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[1] 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 :) [1] project hid-replay, http://bentiss.github.io/hid-replay-docs/
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? Thanks.
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. Closing now
