Hello,
Is it somewhere documented how Xwayland applications are choosing
which compositor to display on? e.g 2 compostiors (1 nested or on
another VT)
wayland-0 and wayland-1
export WAYLAND_DISPLAY=wayland-1
GDK_BACKEND=x11 gedit //starts on wayland-0
If it's not documented how to do it?
Thank you in advance!

Hi,
X programs running through Xwayland connect to it with the exact same
mechanism they use for connecting to a normal X server, which usually
means looking at the DISPLAY environment variable.
Each Wayland compositor would start and manage their own separate
Xwayland server, and would take their own DISPLAY values (e.g.
DISPLAY=:0, DISPLAY=:1).
In the case of the WAYLAND_DISPLAY=wayland-1 compositor's X server takes
DISPLAY=:1, you'd run that command like:
GDK_BACKEND=x11 DISPLAY=:1 gedit
So setting WAYLAND_DISPLAY isn't technically needed, but it's still a
good idea to set it too, because it can have an effect on other
processes which your command can start.
