Subject: [PATCH 1/2] backends/x11: Implement is_grouped for X11
If the devices have a wacom description, compare those. Otherwise,
look up the devices' VID:PID, if they match they should also be
grouped.

From 5914ab9ac79ce42da054036c4a8f118a3a868cc0 Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/2] backends: Check both input settings and mapper for tablet
monitors
The upper layers (OSDs basically) want to know the monitor that a
tablet is currently assigned to, not the monitor just as configured
through settings.
This broke proper OSD positioning for display-attached tablets since
commit 87858a4e01d9, as the MetaInputMapper kicks in precisely when
there is no configured monitor for the given device.
Consulting both about the assigned output will make OSDs pop up
again in the right place.
