GNOME Network Displays on Ubuntu 22.04

Question

I've tested several things to get my projector working with Ubuntu, but only GNOME Network Displays comes close. After establishing the connection, I get errors:

(gnome-network-displays:39996): WARNING **: 22:50:06.762: WfdClient: No resolution found, falling back to standard FullHD resolution.

(gnome-network-displays:39996): GLib-CRITICAL **: 22:50:06.901: g_source_set_callback: assertion 'source != NULL' failed
(gnome-network-displays:39996): GLib-CRITICAL **: 22:50:06.901: g_source_attach: assertion 'source != NULL' failed

What do you think may be the issue?

The projector documentation mention support for IOS and Android only.

Finally, it works. Probably my installation from source was not done properly. Using flatpak make it very easy.

sudo apt install flatpak
flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
flatpak install flathub org.gnome.NetworkDisplays

To run the app:

flatpak run org.gnome.NetworkDisplays

It runs and the TV screen shows the cast icon, nothing more. Any more steps to cast the screen? Thanks. – user227495 Mar 13 '24 at 05:08
Thanks. Please note that it is also available on apt. – Amjad Abujamous Sep 30 '24 at 10:02
