Refresh the README and documentation for public visitors: - README: public-facing rewrite with accurate status for all four native clients (macOS, Linux, Windows, Android) and the Windows host. - docs site: fix stale client status (Android is a full client, not a scaffold; Windows client is stage-1 complete + signed MSIX), add the missing Android client section, correct "which client" guidance. - Windows host: corrected from "deferred/scoped" to implemented & shipping (NVIDIA-only, x64-only) across windows-host, roadmap, status, requirements, running-as-a-service, and the README. - Remove internal infrastructure from public docs (box names, private IPs, SSH/token commands, deploy topology); rewrite status.md as a public project-status page; sanitize ci.md and implementation-plan.md. - Update clients/android and clients/apple READMEs to current state.

title: Troubleshooting
|
||
description: Common problems setting up or using a punktfunk host, and how to fix them.
|
||
---
|
||
|
||
## The host isn't found on the network
|
||
|
||
- Make sure the host is actually running (`systemctl --user status punktfunk-host`, or you see it
|
||
listening in the terminal).
|
||
- Host and client must be on the **same network/subnet**. Discovery uses mDNS, which doesn't cross
|
||
routed subnets or most VPNs-without-multicast. As a fallback, add the host by **IP address** in your
|
||
client.
|
||
- A firewall on the host can block it. The native protocol's control plane uses UDP port **9777**. The
|
||
per-session **data plane** uses an *ephemeral* UDP port negotiated at connect time (currently
|
||
random) — for a strict firewall, open a UDP range or move the data port. GameStream/Moonlight uses
|
||
TCP **47984/47989/48010** + UDP **47998–48010** + ENet UDP **47999**. Allow them on the host's
|
||
firewall.
|
||
|
||
## `nvidia-smi` says it can't communicate with the driver
|
||
|
||
- The NVIDIA kernel module didn't load. With **Secure Boot** enabled, enrol the module's signing key:
|
||
`sudo mokutil --import /var/lib/shim-signed/mok/MOK.der`, reboot, **Enrol MOK** at the blue screen
|
||
(or disable Secure Boot). On Fedora, follow RPM Fusion's Secure Boot steps.
|
||
- After a kernel update the module may need a rebuild — reinstall the driver package.
|
||
|
||
## The desktop won't start, or "GPU … not supported by EGL"
|
||
|
||
The NVIDIA **GL/EGL userspace** is missing — the base driver package doesn't always include it.
|
||
|
||
- **Ubuntu:** `sudo apt install libnvidia-gl-<version>` (matching your driver).
|
||
- Confirm `/usr/share/glvnd/egl_vendor.d/10_nvidia.json` exists and `nvidia-drm modeset` is `Y`.
|
||
|
||
## Black screen / no picture, but the client connects
|
||
|
||
- You must be on a **Wayland** session, not X11 (check the login-screen session picker).
|
||
- KWin must be **≥ 6.5.6** (`kwin_wayland --version`); GNOME **≥ 48**; gamescope **≥ 3.16.22**.
|
||
- Confirm `PUNKTFUNK_COMPOSITOR` in [`host.env`](/docs/configuration) matches your desktop.
|
||
|
||
## Capture fails: "Session creation inhibited" (GNOME)
|
||
|
||
A **locked** GNOME session blocks screen capture. On an always-on/headless host, disable the lock:
|
||
|
||
```sh
|
||
gsettings set org.gnome.desktop.screensaver lock-enabled false
|
||
gsettings set org.gnome.desktop.session idle-delay 0
|
||
```
|
||
|
||
See [Running as a Service](/docs/running-as-a-service).
|
||
|
||
## A controller is detected but does nothing (Bazzite)
|
||
|
||
The host user needs to be in the `input` group. On Bazzite:
|
||
|
||
```sh
|
||
ujust add-user-to-input-group
|
||
```
|
||
|
||
Then log out and back in. On other distros this is `sudo usermod -aG input $USER` + re-login.
|
||
|
||
## Pairing is rejected / the client can't connect
|
||
|
||
- The host **requires pairing** by default. Arm pairing from the web console, then enter the PIN on
|
||
the client. See [Pairing & Trust](/docs/pairing).
|
||
- If you re-installed the host, its identity changed — re-pair the client.
|
||
|
||
## Stutter, drops, or high latency
|
||
|
||
- Lower the **bitrate**. On a busy or Wi-Fi link, the requested bitrate may be too high — the native
|
||
clients' [speed test](/docs/configuration#bitrate) picks a safe value; with Moonlight, set it
|
||
manually.
|
||
- Prefer a **wired** connection or 5 GHz Wi-Fi between host and client.
|
||
- Streaming to **many devices at once** shares the GPU encoder. The production host
|
||
(`serve --native`) handles one native session at a time, with extra clients queued; heavy load is
|
||
usually bitrate-bound, so lower the bitrate first.
|
||
|
||
## Still stuck?
|
||
|
||
Run the host with `RUST_LOG=info` (or `debug`) and check `journalctl --user -u punktfunk-host` for the
|
||
error around the failed connect or capture.
