sunshine on Wayland from the flatpak

[paju1986]

im trying to run sunshine from flatpak on wayland but i dont manage to get it working i get this output:

phone:~$ flatpak run dev.lizardbyte.sunshine
Cannot load libcuda.so.1
[2022:12:16:19:49:36]: Error: Couldn't load cuda: -1
[2022:12:16:19:49:36]: Error: Failed to gain CAP_SYS_ADMIN
[2022:12:16:19:49:36]: Error: Failed to gain CAP_SYS_ADMIN
[2022:12:16:19:49:36]: Error: Couldn't get handle for DRM Framebuffer [86]: Possibly not permitted: do [sudo setcap cap_sys_admin+p sunshine]
[2022:12:16:19:49:36]: Error: Environment variable WAYLAND_DISPLAY has not been defined

reading the docs i find out this command:

sudo setcap cap_sys_admin+p $(readlink -f $(which sunshine))

but it doesnt seem to work, as when running "which sunshine" separately it doesnt found the sunshine binary. I guess it has to do with the flapak being sandboxing or something.
Can someone help here?

Did you follow all the steps here? https://docs.lizardbyte.dev/projects/sunshine/en/latest/about/installation.html#flatpak-package

Make sure you run with sudo -i PULSE_SERVER=unix:$(pactl info | awk '/Server String/{print$3}') flatpak run dev.lizardbyte.sunshine

It turns out to be an issue with the bwrap that ships with fedora. As a workaround, you can set chmod u+s /usr/bin/bwrap.

I'm already cautious about trying such hackish workarounds. Nevertheless, the command won't work on atomic desktop OSes like Fedora Silverblue: chmod: changing permissions of '/usr/bin/bwrap': Read-only file system.

I've tried both system and user-level installs of the Sunshine Flatpak on Silverblue 39 with Wayland (GPU: Nvidia Quadro T1000), following the steps in the official documentation, but Sunshine (0.21.0.5bca024.dirty) continues to report Fatal: Couldn't find any working encoder in its logs.

Stuck at this point.

For Silverblue, you can copy /usr/bin/bwrap to another writable directory (e.g. /usr/local/bin) and then override flatpak's bwrap binary using FLATPAK_BWRAP=/path/to/bwrap flatpak run dev.lizardbyte.sunshine

I'm also on Silverblue and I did not encounter this issue after a fresh install but after upgrading the system, I got this permission denied issue. Either something changed with the bubblewrap package or the newer kernel got more restrictive.

I'm facing the same issue on Fedora silverblue 40, I couldn't find a solution yet

[JumperLuko]

I tried everything, but I needed to use RPM version, because changing bwrap causes problems in other programs like chromium flatpak

Thanks you that works!
but that means i have to always run sunshine as sudo ?

I'm facing the same issue on Fedora Silverblue

Fatal: You must run [sudo setcap cap_sys_admin+p $(readlink -f $(which sunshine))] for KMS display capture to work!
Fatal: Unable to find display or encoder during startup.
Fatal: Please check that a display is connected and powered on.
