Description Chester 2015-08-06 20:47:49 UTC 
Description of problem:
two-finger scrolling in Gnome3 is broken unless launched with wayland.


Version-Release number of selected component (if applicable):
libinput-0.20.0-6.fc22.x86_64
xorg-x11-drv-libinput-0.11.0-3.fc22.x86_64

How reproducible:
Always


Steps to Reproduce:
1. Launch gnome3 on X
2. Attempt to scroll using trackpad
3.

Actual results:
Two-finger scrolling does not work. The checkbox setting is also greyed out in
the mouse settings. This is not the case when gnome3 is launched with wayland

Expected results:
Scroll works


Additional info:

Just to clarify, scrolling also does not work under wayland even though the
setting is togglable.

pls attach an evemu-describe output and the xinput list-props output for the device, and the other things in

Additional information:
The cursor is completely stationary when attempting two-finger scroll. Libinput
knows I'm trying to do something _other_ than move the cursor.
Comment 7 Peter Hutterer 2015-08-07 02:42:26 UTC 
oh, this on is a synaptics semi-mt device. we had to disable 2fg scrolling there because it was too jumpy, but libinput 0.21 (in updates-testing) has that fixed and should work fine again.
