The host warns when its UDP socket-buffer grant is small (Linux caps SO_SNDBUF at net.core.wmem_max, ~208 KB by default). Validated zero-loss at 5K even at that cap, but raising it gives send-side headroom for higher bitrates / concurrent sessions. Referenced from the headless-Steam appliance setup. macOS clients need no tuning. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# punktfunk headless Steam session — systemd USER unit (Bazzite / SteamOS-like hosts).
|
|
#
|
|
# Runs the FULL gamescope-session-plus Steam Deck UI (MangoApp/VRR/controller config — all the
|
|
# polish) headless, at your streaming client's resolution, with no physical display. punktfunk's
|
|
# host then ATTACHES to it (capture its PipeWire node + inject into its libei socket) instead of
|
|
# nesting a second, conflicting Steam — set the host's PUNKTFUNK_GAMESCOPE_NODE=auto +
|
|
# PUNKTFUNK_INPUT_BACKEND=gamescope (see scripts/host.env.example).
|
|
#
|
|
# Prereq — free Steam from the local gaming session (so this owns it), on a headless box:
|
|
# sudo loginctl enable-linger $USER # user services run without a graphical login
|
|
# sudo systemctl set-default multi-user.target # don't auto-start the local gaming session
|
|
# sudo systemctl isolate multi-user.target # stop it now (or reboot)
|
|
# sudo cp scripts/99-punktfunk-net.conf /etc/sysctl.d/ && sudo sysctl --system # big UDP buffers (4K/5K)
|
|
#
|
|
# Install:
|
|
# mkdir -p ~/.config/systemd/user && cp scripts/punktfunk-steam-session.service ~/.config/systemd/user/
|
|
# # edit SCREEN_WIDTH/HEIGHT below to your client's resolution, then:
|
|
# systemctl --user daemon-reload && systemctl --user enable --now punktfunk-steam-session
|
|
#
|
|
# Revert to local gaming mode anytime:
|
|
# systemctl --user disable --now punktfunk-steam-session
|
|
# sudo systemctl set-default graphical.target && sudo systemctl isolate graphical.target
