Description Paul Eggert 2016-09-08 15:31:32 UTC

Description of problem:

(This problem is really annoying.)

In my GNOME Desktop on Fedora 24, scrolling with the mousewheel is backwards from what it was on Fedora 23, or from what it is on Ubuntu. There does not seem to be a way for a user to change this (please see "Additional Info" below for what does not work).

Version-Release number of selected component (if applicable):

Fedora 24 x86-64, gnome-control-center 3.20.1-1.fc24.x86_64

How reproducible:

My desktop uses a Logitech M-SBJ96 (aka M-S48a) Pilot Wheel Mouse, part number 851208-1000. It is a 3-button, wired, PS/2 scroll mouse, where the middle button is the scroll wheel. Fedora 24 is running the command '/usr/sbin/gpm -m /dev/input/mice -t exps2'. 'ls -l /dev/input/mice' reports 13, 63 as major and minor device numbers.

Steps to Reproduce:
1. Log in normally.
2. Run Firefox on any long web page.
3. Rotate the top of the mouse wheel towards me.

Actual results:

The document scrolls to its beginning.

Expected results:

The document should scroll to its end.

Additional info:

The problem does not occur if I select a Wayland login. However, Wayland has another big problem (which I will report separately), so this is not an adequate workaround.

If I run "gnome-control-center mouse" and change the Natural Scroling setting, nothing happens; scrolling is still backwards from what I want.

Comment 1 Paul Eggert 2016-09-08 15:38:21 UTC

I switched to a USB mouse (Logitech Wireless Mouse M510, part number 810-001897) and the problem went away. So this appears to be a problem with PS/2 mice. Since I have a workaround it is no longer urgent for me, though I imagine it will continue to be offputting for other users with PS/2 mice.

Comment 2 Bastien Nocera 2016-10-05 16:20:25 UTC

Do you have either the evdev or synaptics xorg drivers installed?
What's the output of "sudo libinput-list-devices" with the device plugged in?

lsmod does not report either driver. Here is the lsmod output:

Xorg drivers, not kernel drivers. The output of:

The device is detected as a touchpad, so it probably won't work as expected. Reassigning to libinput for root-causing, though the problem might be in the kernel.
