Gnome 3.20 X => Wayland, Apple Magic Trackpad issues

This time round I decided to try Gnome under Wayland again, works fine.

I'm using an Apple magic trackpad though and it seems Wayland handles its input differently. Is it possible to somehow copy the X behaviour over to Wayland? I checked xinput but the trackpad doesn't even have the same id anymore.

Funny thing is that Wayland seems to notice the trackpad is a trackpad and offers me in Gnome settings a touch setting while X only offers mouse settings and no touch settings at all.

What driver had you been using on X?  A generic mouse driver? xf86-input-synaptics? or xf86-input-libinput?

I don't know. Apparently gnome doesn't use synaptics drivers. How can I find out?

Check to see which drivers are installed now with pacman -Qs xf86-input
The best thing to do is boot into the X environment you had been using and look at the Xorg log.

Yes, Gnome does not use the synaptics library.  You might want to look at the xinput command (and its sub commands [check the man page]) and study the properties that command reports.  You can also adjust them with that command

Yes, every single one of them is installed. Can I export xinput settings?

I don't know of any direct way.  But you can set them fairly easily -- https://wiki.archlinux.org/index.php/Li … figuration

ok, thank you. Will update this post once I figured out a working configuation for the Apple Magic Trackpad.

Any updates, dreivier? Did you get it working? Just working through this now... The basic trackpad works (mouse moves and can click things), but I can't work out how to make gestures or multi-touch working.

Thanks in advance!

Oops, totally forgot to update.
Now I can't remember anything anymore since it's just working. I can now set things up via Gnome's settings just nice.

~ xinput list

This is my xinput settings. If you can tell me which other settings you'd like to see I'll happily provide them.
