Dear Maintainer,

Mapping a tablet to a specific monitor using gnome-settings is broken.

The problem is described upstream and seems resolved for gnome 49 but not
backported to gnome 48.

Bug upstream:
https://gitlab.gnome.org/GNOME/mutter/-/issues/4045

Upstream fix:
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4538

I would have to rebuild the package to test the fix (not done yet).

Hi,

I have tried to apply the patch on mutter 48.4-2 (the actual version in
stable) but it did not solve the problem for my setup.

If I find some time I will try it on version 48.4-2 of the proposed
updates. Or maybe the next point release will solve everything.

I have found upstream an other bug/patch that somehow look related.

https://gitlab.gnome.org/GNOME/mutter/-/issues/3443
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4601

So maybe I also have to test this...

Hi,

Just a followup...

The issue is still present with mutter 48.7-0+deb13u1 (Debian 13.3).

I have applied both patches (using the correct branch form salsa) and
installed the patched version of libmutter-16-0, but the problem us
still present.

Maybe I am missing something...

As workaround, as I am still using X11, I use xsetwacom (which has a
MapToOutput option) to map the tablet to the correct display.
