No image, just sound

[cjuniorfox]

I'm trying to use this "gamescope", but I got no image, just sound. Installing Gamescope natively on my OS (Fedora 38), everything works as intended, launching from Hyprland compositor or without any compositor running (straight from tty).

Now, with the Flatpak version of gamescope, I was not able to use it at all. If I try to launch from tty, without any compositor ou X window Manager, I get the error backend 'seatd' failed to open a seat, skipping followed by No backend was able to open a seat. At Hyprland, the application runs, but with no image. Just sound. some logging:

No CAP_SYS_NICE, falling back to regular-priority compute and threads.
Performance will be affected.

You should try https://github.com/flathub/org.freedesktop.Platform.VulkanLayer.gamescope now

Tnx @travier, but I already did. Same thing. Also, today Flatpak told me that this package got the end of like. I'm thinking I'll have to file a bug at the Freedesktop's Gamecope repository.

No, this package is EOL https://github.com/flathub/com.valvesoftware.Steam.Utility.gamescope

and it should be replaced by https://github.com/flathub/org.freedesktop.Platform.VulkanLayer.gamescope

This is an older version of https://github.com/flathub/org.freedesktop.Platform.VulkanLayer.gamescope
