lenovo thinkpad natural scrolling not working for the trackpad after update

English Applications
#1

Hi,

After upgrading from leap 42.2 to 42.3 natural scrolling is not working on my trackpad.

When I go to setting and turn on natural scrolling it works for the red button on the keyboard(did not affect it before) but not the trackpad.

Has anyone experienced this behavior? or know what I could look into?

It could be a possible kernel regression I guess, but good to get some hardware and configuration info reported first…

  1. To get hardware details, do…
/usr/sbin/hwinfo --mouse
  1. Confirm Xorg driver in use for the trackpad
grep "Using input" /var/log/Xorg.0.log
  • I would expect to see libinput, but it might be something else.
  1. What does the following report about your trackpad (assuming libinput is in use)?
sudo libinput-list-devices

The touchpad is using the synaptics driver. You could try seeing the touchpad behaves alright with libinput instead. The easiest way is probably just to remove the ‘xf86-input-synaptics’ package and then restart the X-server (hold down CTRL-ALT-Backspace keys).

sudo libinput-list-devices
libinput-list-devices: command not found

This means ‘libinput-tools’ isn’t installed.

That worked, thanks! Also the pad was to sensitive so when I was writing the original post the cursor was moving all over the place. Now all is good. lol!

Glad to have been of assistance. :slight_smile:
