"Desktop" menu item not showing up in GNOME 3.38
When Cast Media is turned on, the Desktop menu item is missing.
Cast Settings > Modules > Install npm modules is already done.
Please share a little more info about your installation.
What is your Linux distro? What is your version of GNOME Shell? How did you install the "Desktop Add-on" (from gnome extensions page or from github)? Do you have the desktop add-on set to enabled in GNOME Extensions App (or in GNOME Tweaks)?
What is your Linux distro?
$ uname -a
Linux envy-x360 5.8.16-2-MANJARO #1 SMP PREEMPT Mon Oct 19 11:33:03 UTC 2020 x86_64 GNU/Linux
What is your version of GNOME Shell?
$ gnome-shell --version
GNOME Shell 3.38.1
How did you install the "Desktop Add-on" (from gnome extensions page or from github)?
Installed from extensions.gnome.org
Do you have the desktop add-on set to enabled in GNOME Extensions App (or in GNOME Tweaks)?
Yes.
GNOME Shell 3.38.1
I have not tested either cast-to-tv extension or any addons on GNOME 3.38 yet. Probably something in 3.38 caused it to be broken. Again. This happens with EVERY new shell release :disappointed:
Yeah, that's really unfortunate. Gnome Shell really needs to have some kind of BC promise for extensions.
@Rafostar Same issue here on GNOME 3.38.1. Some additional info from the logs:
JS ERROR: TypeError: AggregateMenu._screencast is undefined
@/home/<user>/.local/share/gnome-shell/extensions/[email protected]/recorder.js:4:19
@/home/<user>/.local/share/gnome-shell/extensions/[email protected]/widget.js:5:33
enableAddon/timeouts[addonName]<@/home/<user>/.local/share/gnome-shell/extensions/[email protected]/addons.js:59:27
This is probably the culprit: https://gitlab.gnome.org/GNOME/gnome-shell/-/commit/2b0731ab81887fd9767da73695c754c5b9aadd7c#ca86d9689a6f7702839217d6fd785f78cea7973a
@vincentvanvugt
Thanks. Great find. :+1:
This confirms that it is indeed GNOME 3.38 related. I would need to port it to DBus to get it back working. So a lot of work to be done to get it back and as usual once this is done it will no longer work on older GNOME versions that did not use DBus for screencast API. Usual GNOME stuff :man_shrugging:.
Is there any update for this? Just bought a Chromecast and realized it does not work with my ubuntu 20.10... Happy to help if someone can provide a rough guideline on what to do @Rafostar
@Songyu-Wang
I already mentioned in my previous comment what needs to be done. Someone has to port this extension code to use DBus connection for remote desktop. I am happy to accept a PR if someone manages, otherwise I will probably work on it myself eventually.
Having to redo your extension from zero every 6 months without prior notice is really frustrating. Trust me :disappointed:
Are there any plans to implement this? Also, does Firefox also have to rewrite code everytime GNOME updates so as to share screen on websites like Google Meet? @Rafostar
@Rafostar How about PipeWire?
Eh. This is not a problem with a GStreamer that is used to do recording underneath. This is a problem with GNOME. Once next version of GNOME Shell is released (the so called GNOME 40) neither this or the Cast to TV extension will work anymore. GNOME developers do not provide any code stability for extensions and they do not care if the shell update will break some extensions.
What if this is implemented as a Linux software rather than GNOME extension?

This is the stack trace I get in journalctl when trying to activate this addon in current PopOS which is using GNOME 38:
