Red Hat Bugzilla – Bug 1262434
Two finger scrolling became three finger scrolling
Last modified: 2016-01-20 23:36:01 EST
Description of problem:
I noticed that in the past few days, two finger scrolling seems to have stopped functioning. I do have it enabled in the KDE touchpad settings.
Version-Release number of selected component (if applicable):
% rpm -q libinput
Steps to Reproduce:
1. I'm not confident whether this would affect KDE only, or all libinput environments (I only have KDE), but step 1 for me is to enable two finger scrolling in the KDE settings.
2. Try to scroll with two fingers on a touchpad.
The window should scroll.
I'm using KDE 5.4.1 on a Lenovo X1 Carbon Gen. 3 laptop.
I discovered that this bug has been reported upstream, and that what really happened is that two finger scrolling has become three finger scrolling.
OK, there is definitively a kernel bug here. See:
Josh, can you revert this patch (Input: synaptics - fix handling of disabling gesture mode) from 4.2 and all the branches that F20-23 might be having (or whichever Fedora versions are still receiving some care)?
The fix is worth than the previous bug which was not triggered by most users.
Thus far the commit you highlighted (e51e38494a8ecc18650efb0c840600637891de2c) is only on the rawhide branch. It's queued for 4.1.9 and 4.2.2, so I pinged Greg to see if it can be dropped. Hopefully it won't get backported to those stable branches.
I'll get it reverted in Rawhide today.
OK, reverted in rawhide. The build today should contain that change.
Randy, can you confirm this works?
Hi Peter, it does work! Thanks to Benjamin and Josh for the fix. The funny thing is that I had gotten so used to three finger scrolling that it's taken me a few days to get used to this fix ☺ Rawhide++
Perhaps I should have marked this closed instead of verified. Thanks again for getting this fixed!
