Until now the patched gamescope reached exactly four kinds of box: the Bazzite/Fedora-Atomic sysext, the Arch package, the SteamOS installer and a NixOS option. Everyone else was told to build gamescope from source. A traditional Fedora-family box — Nobara, plain Fedora, the HTPCs people actually stream from — therefore ran stock gamescope by default, which streams SDR, cursorless, and tells every game its display is 60 Hz. That is not a user error; there was no package to install. Both new packages REPACK the binary CI already builds rather than building gamescope again: it is a ~10-minute meson compile of an unrelated tree, cached per distro base because the binary is soname-coupled to it. The Arch PKGBUILD stays the one recipe that builds from source, because that is what makepkg is for. - packaging/gamescope/punktfunk-gamescope.spec + build-gamescope-rpm.sh. Version is derived from the binary's own banner (3.16.25.pfhdr4) — the only source that cannot drift from what is in the package. rpmbuild's automatic ELF Requires are what stop an f43 build installing on f44. - packaging/debian/build-gamescope-deb.sh, same shape, with dpkg-shlibdeps for Depends. - rpm.yml packages and publishes it beside the host RPMs; deb.yml gains a cached gamescope build (keyed on packaging/gamescope/** alone) and packages it into the existing publish loop. Both legs are best-effort, matching the sysext's existing rule: no binary, no package, and the host stays on its current SDR path. Neither package Provides or Conflicts with gamescope — it installs as /usr/bin/punktfunk-gamescope and only the sessions the host starts itself resolve it, so a box's own Game Mode keeps using the distro binary. Both refuse to package a binary without the +pfhdr marker. That marker is the host's entire capability probe, so a build that lost the patches would install fine and then silently stream SDR with no cursor. Verified: build-gamescope-deb.sh produces an installable .deb from a stand-in binary (correct version derived from the banner, 0755 tree, control fields) and exits 1 on an unmarked one. The .spec is not yet exercised — no rpm tooling on the box I had; CI's Fedora leg is its first run.

# Package an already-built punktfunk-gamescope binary as an RPM, for the Gitea RPM registry.
|
|
#
|
|
# WHY this exists: before it, the only ways to get punktfunk-gamescope were the Bazzite/Atomic
|
|
# sysext, the Arch package, the SteamOS installer, a NixOS option — or building gamescope from
|
|
# source yourself. A traditional Fedora-family box (Nobara, plain Fedora, Nobara-derived HTPCs)
|
|
# had no packaged route at all, which is how a field report ended up on a stock gamescope streaming
|
|
# a session that told every game the display was 60 Hz.
|
|
#
|
|
# The binary is NOT built here; CI builds it once per Fedora major and caches it
|
|
# (.gitea/workflows/rpm.yml). See punktfunk-gamescope.spec's header for why repacking beats
|
|
# rebuilding.
|
|
#
|
|
# Usage:
|
|
# bash packaging/gamescope/build-gamescope-rpm.sh \
|
|
# --binary gs-cache/punktfunk-gamescope \
|
|
# [--version 3.16.25] [--release 1] [--outdir dist]
|
|
#
|
|
# Output: <outdir>/punktfunk-gamescope-<version>-<release>.<arch>.rpm
