There is <a href="https://phabricator.freedesktop.org/T63" rel="noreferrer" target="_blank">https://phabricator.freedesktop.org/T63</a> with some hints. One key point I believe is that Weston expects the VT to be already active where it will be started on. That might use some fixing in Weston, but without breaking setups that have no VTs. > > This is really not meant to be used like you use it.

Correct, patches to add autolaunch feature were started but never finished: <a href="https://lists.freedesktop.org/archives/wayland-devel/2014-October/017971.html" rel="noreferrer" target="_blank">https://lists.freedesktop.org/archives/wayland-devel/2014-October/017971.html</a> > What you see there is what Tizen does (or used to do) together with every > other Kiosk based on Weston. > > Is there any other way to launch a full screen-kiosk app if not through > shell? Perhaps with a systemd unit? Conceptually, both Weston and the app should be launched from a systemd user session, because Weston is supposed to run in a valid session. I just don't know how to do auto-login with systemd, and the other issue is the VT switching. Weston also supports systemd socket activation and watchdog, if you load Weston's systemd plugin. The plugin also provides start-up notification so that systemd won't start dependent services too early AFAIU. > > E.g. if you have a floating window, and you want to resize it by dragging > a pointer, the cursor is left as what the app last set it, rather than the > cursor the compositor would pick. > > Benja is a Web Kiosk, has no floating window, just evnetually Gtk modals > and these show up fine. > > > > You cannot have screen locking. > > I've posted my configuration which disables screen locking, not an issue. > > > > Indications for frozen app windows is missing. > > if the browser freeze there's nothing else Benja can do if not a browser > reset Indications for the user; For frozen windows, weston is intended to show a busy cursor. In your case, the cursor will be left what ever it happened to be, the browser window is frozen, and no other indication is given to the user. The cursor will stil move. If your browser was managed by systemd, you could implement the systemd watchdog in the browser process and have systemd restart the browser if it hangs. Weston also detects frozen windows, but does not implement an auto-kill or restart. > > The compositor start-up will take long, because it needs to time out before > fading in since the shell client is not signalling ready.

You missed the point. Mod+tab makes windows temporarily semi-transparent. That effect will probably screw up if there is no opaque surface at the bottom of the scenegraph (the wallpaper). Users can also use the mouse and keyboard to make windows semi-transparent. > > Those are just what came to mind off-hand, there's possibly more. > > If you think there are more specific for Benja use case please let me know > 'cause so far .... > > > > So yeah, it probably works for you for now, if you don't pay attention to > details and nothing in apps ever fails.

You are abusing a feature of weston in a way it was never meant to be used, and is not intended to keep on working. It's your choice, at least now you know there might be issues. In the future the special shell client will likely gain more responsibilities. Whether that will break your use case or not remains to be seen.
