Description of problem: I'm trying to get natural scrolling enabled on a Samsung Series 9 15" notebook. The notebook uses an Elantech touchpad, identified as "ETPS/2", and is running Fedora 24 with Gnome on Wayland. There was no touchpad configuration options available in gnome-control-center, so it was necessary to create a configuration file: $ cat /etc/X11/xorg.conf.d/30-touchpad.conf Section "InputClass" Identifier "libinput pointer catchall" MatchIsPointer "on" MatchDevicePath "/dev/input/event*" Driver "libinput" Option "NaturalScrolling" "true" EndSection Section "InputClass" Identifier "libinput touchpad catchall" MatchIsTouchpad "on" MatchDevicePath "/dev/input/event*" Driver "libinput" Option "NaturalScrolling" "true" EndSection After this, the option to enable/disable natural scrolling appeared in gnome-control-center. I don't imagine it should have been necessary to create this file to enable this functionality. This device is still registering itself as a pointer device (a pseudonym for a mouse?), when I think it should be registering as a touchpad. I've included additional output from xinput and libinput utilities. Version-Release number of selected component (if applicable): * Fedora 24 (4.6.6-300.fc24.x86_64) * libinput 1.4.1 * Gnome 3.20 How reproducible: Always Steps to Reproduce: 1. Open 'gnome-control-center' 2. Click "Mouse & touchpad" Actual results: There should be options to configure natural scrolling and other touchpad features. Expected results: The only option is to switch left and right click.

what happens if you remove the Driver "libinput" line from your snippet? I suspect that what possibly happens here is that some other snippet assigns the synaptics driver which isn't supported by the control center anymore. do you by any chance have xorg-x11-drv-libinput-0.19.0-1 installed? if so, update to -2 please.
do you have cinnamon installed? I think it installs some override to force synaptics over libinput.

I removed that snippet and rebooted. The output of 'xinput', 'xinput list-props' and 'libinput-list-devices' remains the same. I am using -2 already (In reply to Ray Strode [halfline] from comment #2) > do you have cinnamon installed? I think it installs some override to force > synaptics over libinput. I do have the Cinnamon spin installed, yes, and sorry for not including that in the original bug report. However, I have since installed Gnome, configured gdm, and removed any Cinnamon or lightdm-related package I could find. It's pretty much the standard Workstation (?) release now.
do "dnf remove xorg-x11-drv-synaptics" fix it?
(In reply to Ray Strode [halfline] from comment #4) > do "dnf remove xorg-x11-drv-synaptics" fix it? After removing the xorg-x11-drv-synaptics package and the '30-touchpad.conf' file, it seems the options appear in gnome-control-center as expected. Good stuff :) The device is still listed as having only 'pointer' capability via 'libinput-list-devices' though. Is this expected?
(In reply to Stephen Finucane from comment #5) > The device is still listed as having only 'pointer' capability via > libinput-list-devices' though. Is this expected? yep, touchpads don't have their own capability since they're just pointer devices.
