[Feature Request] A way to set a default monitor for WSLg apps to open on

[fahim2690]

Is your feature request related to a problem? Please describe.

Hi, I'm wondering if there's a way to force Weston to open WSLg windows on a specific monitor by default (e.g. my second monitor). I can see from xrandr that the two monitors that I have here are getting recognized as separate output options but if I say override it with DISPLAY=XWAYLAND1:0 for an XWayland app it seems to ignore keypresses or just not be able to launch and I haven't figured out a way to override this for native Wayland apps yet. I'd prefer not to set my second monitor as my primary monitor as that seems to make some native Windows apps like HWInfo launch out of bounds (my main monitor is 4K, my secondary is 1080p).

Describe the solution you'd like

As the title says, I'd like to be able to configure which monitor GUI apps launch on by default, maybe this is already possible with one of the WESTON environment variables but I've not seen one documented yet.

Describe alternatives you've considered

Not much really, I'd prefer not to go back to the days of using VcXsrv so here I am.

@farahnur42, thanks for feedback, I guess this is same root as the issue discussed at #89. And for default window placement, it's not configurable today, and the default place is done https://github.com/microsoft/weston-mirror/blob/34989f76bbe011d64715c14a9901d34af111d58a/rdprail-shell/shell.c#L3737, which normally ends up on 'primary' monitor unless application specify the position, thanks!

Hi, thanks for your reply - I guess I'll just have to live with it for now.
