Logitech Trackman Marble

I have recently purchased a Logitech Trackman Marble:

This trackball does not have a scroll wheel, but I read some guides on how to get a scroll wheel working with this mouse by holding down the small left button and then turning the wheel.

I found this wiki article in the Arch Wiki:

https://wiki.archlinux.org/index.php/Lo … rble_Mouse

Since I am running Gnome 3.36.1 on Wayland, I entered the following command, as recommended by the Wiki:

gsettings set org.gnome.desktop.peripherals.trackball scroll-wheel-emulation-button 8

In order to get this to work, however, I need to unplug the trackball and plug it back in.  And the setting goes away after I reboot my laptop.

How do I make it stick and work after a reboot or logout?  My initial thought was to make a bash script and use systemd to launch it when I login, but that would still involve me needing to unplug the trackball and plug it back in.

Ok, I double checked and it appears the setting does indeed stick.  When I go into dconf, it is set to 8.

But it will not apply, even after a reboot, unless I unplug the mouse and plug it back in.

Re: Logitech Trackman Marble

Just make an Xorg.conf snippet rather than depending on gnome to handle this for you.  This will work every time X starts, and it is more general if you ever want to use something other than gnome.

EDIT: oops, sorry, I missed that you are using wayland.  I don't know any way to do the equivalent there.

According to the wiki, x.org snippets won't work, since I am using Wayland.  The only thing that works in Wayland is the gsettings.

Re: Logitech Trackman Marble

Switching to Gnome on x.org with the  example config for libinput seems to work perfectly.  I'll stay on x.org now.
