[PATCH v3 xserver 1/2] xwayland: Add optional xdg-output support
Olivier Fourdan
ofourdan at redhat.com
Thu Sep 7 15:43:16 UTC 2017
The xdg-output protocol aims at describing outputs in way which is
more in line with the concept of an output on desktop oriented systems.
For now it just features the position and logical size which describe
the output position and size in the global compositor space.
This is however much useful for Xwayland to advertise the output size
and position to X11 clients which need this to configure their surfaces
in the global compositor space as the compositor may apply a different
scale from what is advertised by the output scaling property (to achieve
fractional scaling, for example).
This was added in wayland-protocols 1.10.
