Describe the Bug

I've been trying to run the Sunshine flatpak on Fedora atomic desktops running Wayland, however, I keep seeing this error even after following this guide here https://docs.lizardbyte.dev/projects/sunshine/en/latest/about/setup.html#install

Attention! Sunshine detected these errors during startup. We STRONGLY RECOMMEND fixing them before streaming.

    Fatal: You must run [sudo setcap cap_sys_admin+p $(readlink -f $(which sunshine))] for KMS display capture to work! If you installed from AppImage or Flatpak, please refer to the official documentation: https://docs.lizardbyte.dev/projects/sunshine/en/latest/about/setup.html#install
    Fatal: Unable to find display or encoder during startup.
    Fatal: Please check that a display is connected and powered on. 

I've also searched and read through other issues (e.g. #2840), however, nothing has worked for me.

The flatpak works on X11, but not on Wayland.

I've tried the latest release as well as the pre-releases with no luck.

Sunshine flatpak should run on Wayland

What is the command you used to start Sunshine?

[wiseindy]

First I run setcap (got this from #2840), followed by flatpak run

sudo setcap cap_sys_admin+p $(readlink -f $(find /var/lib/flatpak/app -name sunshine | grep /bin/sunshine))
flatpak run dev.lizardbyte.app.Sunshine

[ReenigneArcher]

I have no idea if that command works. I expect it doesn't due to the sandboxing of flatpak.

This is the command in our docs for the pre-release.

sudo -i PULSE_SERVER=unix:$(pactl info | awk '/Server String/{print$3}') \
  flatpak run dev.lizardbyte.app.Sunshine

https://docs.lizardbyte.dev/projects/sunshine/en/master/about/setup.html#install

[wiseindy]

Yeah I tried that too. Sunshine doesn't start

$ sudo -i PULSE_SERVER=unix:$(pactl info | awk '/Server String/{print$3}') \
  flatpak run dev.lizardbyte.app.Sunshine
bwrap: Can't find source path /run/user/1000/pulse/native: Permission denied

The path does indeed exist

$ ls /run/user/1000/pulse/native
/run/user/1000/pulse/native

$ (pactl info | awk '/Server String/{print$3}')
/run/user/1000/pulse/native

I've tried giving additional permissions to Sunshine flatpak via Flatseal, tried a reboot as well. No luck

[ReenigneArcher]

Sorry, I don't know. Maybe @istori1 has some idea?

[wiseindy]

No worries, thank you for helping!

For the bwrap issue, I came across this https://github.com/LizardByte/Sunshine/discussions/569#discussioncomment-8654055, but it didn't help sadly

$ cp /usr/bin/bwrap /home/<user>/writable/dir/

$ sudo -i PULSE_SERVER=unix:$(pactl info | awk '/Server String/{print$3}') FLATPAK_BWRAP=/home/<user>/writable/dir/bwrap flatpak run dev.lizardbyte.app.Sunshine
bwrap: Can't find source path /run/user/1000/pulse/native: Permission denied

It's this combination of Flatpak + Wayland + Atomic desktop which is proving to be a challenge. Switching to X11 or a non-atomic desktop works.

Are there any reports of the above combination working for anyone?

[ReenigneArcher]

Atomic desktop

Honestly, I've never heard of it.

[AesaraB]

Atomic desktop

Honestly, I've never heard of it.

It's basically an operating system with much of the root filesystem locked down as read-only

[XT-Martinez]

Are there any reports of the above combination working for anyone?

You forgot to grant bwrap setuid

chmod u+s /home/<user>/writable/dir/bwrap

There is also a custom variant of bwrap in COPR but I haven't tried it yet.
It has instructions for rpm-ostree based distros.

I've inadvertently mirrored this issue here - #3181

I do not know how to consolidate.

If you have an intel iGPU, use it instead to nip this issue.

It is making the AMD encoder unusable - I would rather haul my gaming pc around with me than put up with this incredibly blurry result.

[ReenigneArcher]

I'm working on adding an automated copr build here: #3239

If there's any fedora/copr experts here, I could use some assistance with a few things.

[ReenigneArcher]

I wouldn't suggest using flatpak on an atomic os, as you can't run the additional install steps. Instead you should use the RPMs.

For the RPMs:

The atomic desktop issue was fixed by #3050

Also...

LizardByte now has copr repos you can use to install Sunshine. Currently fedora 39-41 and rawhide are supported for aarch64 and x86_64. All builds also have cuda support (v12.6.2).

https://docs.lizardbyte.dev/projects/sunshine/en/master/md_docs_2getting__started.html#fedora

Note: stable will be empty until the next stable release.

Anyway, closing this as I don't believe there is anything we can do to make flatpak work on atomic desktops.

[jwmullally]

Think I have the same issue.

This flatpak used to work great last year on Fedora Silverblue 39 (aka Fedora Atomic Workstation, rpm-ostree based) for Steam etc and without needing any extra rpmfusion RPMs.

Now it no longer works on Fedora Silverblue 40:

sudo -i PULSE_SERVER=unix:/run/user/$(id -u)/pulse/native flatpak run dev.lizardbyte.app.Sunshine
bwrap: Can't find source path /run/user/1000/pulse/native: Permission denied

When I leave out PULSE_SERVER, it starts OK and has no sound, but also the video feed on the client shows as a black screen. This might be related to new Wayland screen sharing features and permissions, so there looks to be 2 separate issues with video and sound.
