Hello! I’m trying to cast from my laptop to a Samsung smart television.
Neither of the two (2) available methods that I know of work.
Gnome Network Displays
Doesn’t get past selecting the TV in the dialogue it opens. Relevant errors from running it in the terminal:
(gnome-network-displays:15836): Gnd-WARNING **: 16:52:08.280: Failed to create screencast session: GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: No such interface “org.freedesktop.portal.ScreenCast”
Every time I click the menu entry, it prints that again.
Doesn’t matter if I run it as sudo or not, or if I install it from DNF or Flathub.
Evidently, a bug report and subsequent fix for this were on the way. This either has not arrived to the Flatpak, or doesn’t actually fix it. I acknowledge the possibility there is also a problem on my end, but I have tried to sudo dnf install xdg-desktop-portal and related packages, however they were already installed.
Miraclecast
Doesn’t get past electing my laptop screen as a peer.
The instructions are vague and the method itself is prohibitive in that it requires me to turn off Wi-Fi, which, I would need for the activity I intend to do with this smart television. I do not have access to Ethernet.
Relevant terminal output:
$ sudo miracle-wifictl --log-level trace

I also recognize the possibility that this is a doomed endeavour, for the smart television itself only acknowledges casting from Windows machines in its help interface.
For the moment, I will procure an HDMI cable, but I would rather not have to do this in the future.
