I have the following error message :

bt@zero:~$ flatpak run org.gnome.NetworkDisplays

According to this web page, pipewire is needed:

Zorin is using pipewire version 0.3.48-1ubuntu3 and the flatpak info says that it need pipewire 0.3.8 or more. So this may be the culprit. Zorin didn't install the correct version. I'm not sure if I can upgrade to 0.3.8 without causing others problem since pipewire is made of few libraries and binaries and is used by other apps. It seems that gnome-network-displays as installed by zorin is unusable.

Last version of pipewire is 1.0.5 dated 2024-04-15. Pipewire passed 1.0.0 version since the beginning 0f 2024. We need a more recent version on Zorin...

PS: I don't get why this flatpak has dependencies on the host ???

Not sure if this could work for you:

I will try at home tonight.
Thanks :+1:t2:

The article is a bit old. But I used the README to install all reported dependencies.
I'm still strugling to find one dependency to be able to compile gnome-network-displays
I'm stuck at this error :

Found CMake: /usr/bin/cmake (3.22.1)
Run-time dependency gtk4 found: NO (tried pkgconfig and cmake)

src/meson.build:36:0: ERROR: Dependency "gtk4" not found, tried pkgconfig and cmake

Update: I have installed libportal-gtk4-dev and it seems to be ok but now I don't have a enough recent version

src/meson.build:36:0: ERROR: Invalid version of dependency, need 'libportal-gtk4' ['>= 0.7'] found '0.6'.

I'm afraid I cannot compile gnome-network-displays 1.1 on zorin gnome 42 ...

I share your frustration. I have been having similar experiences on pclinuxos, not in terms of screen sharing but other apps, but slowly getting there, baulked by another dying hard drive, this time a Samsung drive. See if you can find an online source. One of the apps I had been having issues with was a lack of the app, Linux Intelligent OCR Solution (LIOS), currently at version 3.0 but only available from GitLab and had to sign up for an account to download the source code. Couldn't get any further until I found version 2.8.1 on Sourceforge. Fortunately, just before hard drive failure, I had to install 2 dependencies that were available via Synaptic and in order to get it to run, I had to:

chmod 775 lios

so that I as a user instead of root, could launch it.
