`punktfunk-gamescope` had never been published to the apt registry — not in any release. It was built inside the host job's Ubuntu 24.04 image, where it cannot build: our pin vendors wlroots 0.19.3, which floors `wayland-server` at 1.23.1, and noble ships 1.22.0 (it also lacks libxcb-errors-dev and has only libdisplay-info 0.1.1). Every rung of that path was a `::warning::` returning 0 and the one hard gate ran last by design, so v0.26.0 and v0.27.0 both released with the package missing while docs-site told apt users to install it. The same tags shipped it fine for Arch, Fedora 44 and Bazzite. It now builds in its own job on Debian 13 (ci/gamescope-trixie.Dockerfile), the oldest apt base the tree configures on. One package serves Debian 13 AND Ubuntu 26.04 — measured by installing and running it on both — because the build also vendors libdisplay-info via the new `--extra-fallback` option: linked against the distro copy it demands `libdisplay-info2` on trixie, which Ubuntu 26.04 does not have (it carries libdisplay-info3). The option is opt-in, so the Arch/Fedora/nix outputs are byte-for-byte unchanged. Ubuntu 24.04 gets no gamescope package and cannot — its wayland is too old to run one however built. Debian 13 is now a documented host target. That needed no packaging change at all: the host .deb's glibc-2.39 floor and bundled FFmpeg already made it installable, and it had been working for a long time while docs-site said Debian was unsupported and unverified. Verified by installing: host, web console and plugin runner install, resolve every soname and run. The desktop client stays Ubuntu-26.04-only (built there, floors at `libc6 >= 2.43`; Debian 13 has 2.41). Compositor detection now answers Cinnamon (Mint, LMDE) with the route that works instead of advice that cannot help. Muffin forked from Mutter 3.36: `org.cinnamon.Muffin.ScreenCast` has only RecordMonitor/RecordWindow, never RecordVirtual, and xdg-desktop-portal-xapp implements no ScreenCast — so no value of PUNKTFUNK_COMPOSITOR makes a Cinnamon desktop host a virtual display. The error names headless gamescope, which needs no desktop compositor. The XDG sniff moved into a pure function so those branches are testable; Cinnamon is matched before GNOME, since it is a GNOME derivative and the generic arm would otherwise hand it the Mutter backend (caught by the new test). New `smoke-install` job installs every published package from the registry in pristine ubuntu:24.04, ubuntu:26.04 and debian:trixie images, asserts each binary resolves its libraries and runs, and insists the version served is the one this run built. Nothing in deb.yml had ever installed a package it produced, which is how both of the above survived unnoticed. ⚠ Bootstrap: seed `punktfunk-gamescope-trixie:latest` into the LAN registry once (docker.yml builds it thereafter) or the new job cannot start.

# Builder for the `punktfunk-gamescope` .deb — Debian 13 (trixie).

#
|
|
# WHY THIS EXISTS, AND WHY IT IS NOT THE NOBLE IMAGE:
|
|
# The gamescope .deb was built in the host job's Ubuntu 24.04 (noble) image, and it has NEVER once
|
|
# succeeded there — v0.26.0 and v0.27.0 both shipped with no gamescope package while the release
|
|
# notes and docs-site said it was apt-installable. The failure is structural, not a flaky dep:
|
|
#
|
|
# wlroots| Dependency wayland-server found: NO found 1.22.0 but need: '>=1.23.1'
|
|
# subprojects/wlroots/meson.build:96:17: ERROR: Dependency 'wayland-server' is required but not found
|
|
#
|
|
# Our gamescope pin vendors wlroots 0.19.3, which floors wayland-server at 1.23.1. Noble ships
|
|
# 1.22.0 and will never ship more — so no amount of `apt-get install` in that image can fix it.
|
|
# Noble also has no `libxcb-errors-dev` at all and only libdisplay-info 0.1.1 (the tree wants 0.2).
|
|
#
|
|
# Debian 13 ships wayland 1.23.1 exactly, libxcb-errors 1.0.1 and libdisplay-info 0.2.0 — the
|
|
# oldest apt distro the tree actually builds on. Building HERE rather than on Ubuntu 26.04
|
|
# (wayland 1.24, libdisplay-info 0.3) is deliberate twice over: it keeps the glibc floor low, and
|
|
# it stays on the libdisplay-info 0.2 line the pin was developed against.
|
|
#
|
|
# WHAT THE RESULTING BINARY RUNS ON — verified by building it and reading the ELF:
|
|
# * glibc floor GLIBC_2.38 (the C++ runtime is linked statically by
|
|
# build-punktfunk-gamescope.sh, so libstdc++ never enters the NEEDED list)
|
|
# * NEEDED libwayland-server.so.0 / libwayland-client.so.0 — wlroots 0.19 calls symbols
|
|
# added in 1.23.1, so THAT, not glibc, is the real floor.
|
|
# ⇒ Debian 13 (1.23.1) and Ubuntu 26.04 (1.24.0) YES; Ubuntu 24.04 (1.22.0) NO — and 24.04
|
|
# could not run this binary however it was built, so nothing is lost by moving off noble.
|

#

# Rebuilt+pushed by .gitea/workflows/docker.yml (matrix: punktfunk-gamescope-trixie); consumed by
|
|
# the `build-publish-gamescope` job in .gitea/workflows/deb.yml. Bootstrap: like rust-ci-noble, the
|
|
# first deb.yml run after this image is added needs the image to already exist — seed it once by
|
|
# hand (docker build -f ci/gamescope-trixie.Dockerfile -t <registry>/punktfunk-gamescope-trixie:latest ci
|
|
# && docker push …) before that job can run.
