Body

I installed sunshine on fedora 41 via flatpak and everything went well. However, only the desktop appears as the application to start, and when I try to add Steam or another application, it either gives an error or does not start.

Is steam installed via flatpak?

[IagoMullerDev]

I installed it from the Fedora store. the source says: from Fedora Linux

[ReenigneArcher]

Try to prefix the commands with flatpak-spawn --host

Am I doing something wrong?

[IagoMullerDev]

From what I noticed, in these lines he tries to run Steam in big picture, but it aborts and launches the desktop, wouldn't that be it?

[ReenigneArcher]

You didn't update the command per my suggestion.

[IagoMullerDev]

After the command was done, I gave sudo dnf update and sudo dnf upgrade. and then I restarted my computer, but the error persists

[ReenigneArcher]

Your command is setsid steam steam://open/bigpicture but needs to be flatpak-spawn --host setsid steam steam://open/bigpicture

[IagoMullerDev]

The error has been resolved, I apologize. I just put the code wrong and that caused the malfunction. but I understood correctly and now everything is working perfectly, thank you very much! I apologize if I caused any inconvenience
