Set primary screen

[guilhem]

(at least on Wayland) current behavior is to spawn terminal on current (mouse focus) screen.

Can it be able to set it on primary screen?

[amezin]

Unfortunately, no. GNOME's window manager tries to move all new windows to the current screen. When the extension tries to do something different, the result is crap. Though, honestly, I prefer the terminal window on the current screen, so I didn't invest too much time into this and gave up quickly

That's a real pity. Hopefully you will keep an eye on it, as it is mildly annoying ;p

This feature will also require #45 if it will ever be implemented

Tried again today, still not working properly: the window initially appears on the "current" monitor, then moves to the specified one, and I can't do anything about that. This also breaks animations when current != specified. I definitely don't want to ship it in this state.

[amezin]

So it seems that the window initially flashes on current monitor because it's setting gtk-window-object-path (and other d-bus properties) too late (when the window is already visible). And I use that property to detect ddterm's window. The problem is - I can't find any other way to detect the window on Wayland

.get_pid() on 3.36 Wayland does not work :(

At least I can filter windows based on .get_wm_class_instance(). Though that won't filter out dialogs and popups created by ddterm. Well, maybe popups will be distinguishable by other properties... But dialogs on Wayland won't

[amezin]

Even wm_class and title are set too late

[amezin]

And trying to move all windows that belong to WaylandClient to the correct monitor from Meta.Display.window-created handler crashes GNOME Shell.

[amezin]

Though no, it can't be "too late", Window.shown arrives even later on Wayland.

[amezin]

Changed my mind about this. Even though I can't get it to work perfectly on Wayland native (window initially flickers on wrong monitor), it's usable. And on X11/XWayland everything works as it should.

Will be available in v19
