global.screen is undefined error on gnome-shell 3.30 (running on antergos)

See original GitHub issue

I’ve just upgraded my antergos station and now pixel saver no longer works

Running lg shows:

Type Error: global.screen is undefined.

and this is the result of journalctl

$ journalctl -f /usr/bin/gnome-shell

Some more info:

$ uname -a
Linux antergos 4.18.8-arch1-1-ARCH #1 SMP PREEMPT Sat Sep 15 20:34:48 UTC 2018 x86_64 GNU/Linux

$ gnome-shell --version
GNOME Shell 3.30.0

There seem to be several extensions facing similar issues:

https://github.com/zakkak/workspace-grid/issues/86 https://github.com/home-sweet-gnome/dash-to-panel/issues/434 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=905107 https://github.com/codito/gnome-pomodoro/issues/365 https://github.com/mlutfy/hidetopbar/pull/163 https://github.com/mlutfy/hidetopbar/issues/162

it seems like global.screen is now globa.display

+        if (global.screen)
+            stackingManager = global.screen;    // mutter < 3.29
+        else
+            stackingManager = global.display;   // mutter >= 3.29

I saw the following comment on the [extension page}(https://extensions.gnome.org/extension/723/pixel-saver/):

to make it work on Gnome 3.30 (and ubuntu 18.10 probably) :

edit$HOME/.local/share/gnome-shell/extensions/pixel-saver@deadalnix.me/utils.js

edit$HOME/.local/share/gnome-shell/extensions/pixel-saver@deadalnix.me/decorations.js replace global.screen by global.workspace_manager everywhere

alt f2 r to restart gnome.

The fix works ok, perhaps you could add it to the extension

@SpaceboyRoss01 The version from this repo works without problems on GNOME 3.30.
