* chore(i18n): translate every missing string in all locales Adds the 87 strings the bottom-screen Dashboard and in-game stats pages introduced to all 32 locales, plus the 51 older settings strings Japanese and the 50 Chinese locales were still missing. Every locale now has all 3456 translatable strings with the same placeholders as English. Also translates 36 entries that were still English where the language does not use the English word, and makes es-419 touch_app_id use the same %1$s placeholder as English. * chore(patches): drop comments from the lines downstream patches add Removes comment lines and trailing comments from lines our patches add, with hunk headers recounted. Lines that a later patch uses as context and the upstream backport 0123 are left as they are. The gamescope, FEX, proot and xodus series still apply to their pinned sources, and the patched trees differ only in those comments. test_hud_frames now finds the HUD writer by its first declaration. * docs: credit Greenlight, Better xCloud, viture-v2, GameNative and DiRTTelemetryErrorFix These were credited only in source headers and NOTICE files. * chore: remove source comments and unused functions Removes explanatory comments from first-party Kotlin, Java, C, C++, Rust, TypeScript, Python, shell, Gradle, CMake and workflow files. License and attribution headers stay, and vendored third-party trees, generated files and license files are untouched. A shellcheck directive is kept, and udevmon's fallthrough comments became fallthrough attributes. Syntax trees and token streams match the previous sources apart from the comments and Python docstrings. Module docstrings that argparse prints are kept, and device-smoke.sh prints the same --help text from a heredoc. Also removes 37 functions and 4 fields that nothing referenced. * chore: remove comments from the Syncthing integration and the latest main sources * docs: credit Syncthing and the syncthing-android fork * chore(i18n): translate the Syncthing strings in all locales The 107 strings the Syncthing integration added are now in all 32 locales. sync_web_path_locked names the Syncthing tab by its label. * docs: credit @xXJSONDeruloXx for the HUD metric readers The CPU, GPU load, thermal and battery readers come from their PerformanceHudView pull requests #777, #877, #991, #1406 and #1573. The FusionHUD credit line is unchanged. * docs: credit the HUD metric readers to @xXJSONDeruloXx's work
The desktop package (KDE Plasma)
The desktop the app installs into its Linux runtime the first time the desktop is opened: KDE Plasma set up as SteamOS's desktop mode, with Valve's Vapor theme, the Steam Deck wallpaper and launcher icon, Plasma's default bottom panel, and "Return to Gaming Mode" and Steam on the desktop.
seeds.txt: the packages asked for.build.shtakes their closure over Arch Linux ARM's repositories (closure.py) and drops what the runtime already has.runtime-packages.txt: the runtime's own packages,name versionfrom its pacman database (ls /var/lib/pacman/localin the rootfs). Refresh it when the runtime is rebuilt.overlay/: our files on top - system-wide KDE defaults in/etc/xdg, the Vapor theme and its layout script, the menu entries Steam and Return to Gaming Mode use.
pacman works on the desktop. pacman-db.py writes an install record for every package the desktop
ships into /var/lib/pacman/local, and builds the droiddeck repository: Arch Linux ARM's core,
extra and alarm databases as they were at build time, with the runtime's and the desktop's own
packages at the installed versions. The release carries that database (droiddeck.db) and the
packages mirror.txt names; everything else downloads from Arch Linux ARM as a CacheServer, so its
404s never disable a mirror. Installs therefore resolve against the desktop's exact Qt and KDE
versions, and pacman -Syu only ever moves packages the user added.
/usr/local/bin/pacmanruns the real pacman with/usr/share/droiddeck/pacman/pacman.conf, first copying in the shipped database and dropping the runtime's records for packages the desktop replaced (prepare). As root it adds--neededto installs, so guides that reinstall something the desktop has just skip it.sudo,suandsudoeditrun commands as root: the session is the app's own Android user, andlibdroiddeck-root.so(root/root.c, preloaded bysudo) reports uid 0, accepts ownership changes and shows the runtime's 0700 directories as 0755. It grants nothing the user lacked.hooks/droiddeck-system.hookrefuses to remove or replace any runtime or desktop package;droiddeck-remember.hookkeeps the user's own packages in~/.local/share/droiddeck/pacman/packages.txt, andrestore(autostarted) reinstalls them after a runtime update and upgrades them after a desktop update. Hooks that need systemd, udev, kernel modules or an initramfs are masked.
.github/workflows/build-desktop-kde.yml builds it and, run with a new tag, publishes it as a
release in Droid-Deck/DroidDeck-Components (tags with -rc are published as pre-releases for testing
before an app build points at them). release.env pins the tag, sha256 and size the apk
installs (DesktopCatalog.desktopEntry); a published tag is never replaced, so a changed package
is a new tag and a release.env update.
At run time the desktop is started by tools/linuxfs/desktop/droiddeck-desktop (the app stages it
at every session): Plasma's own startplasma-wayland, with KWin nested in the app's compositor
through kwin_wayland_wrapper. The package's kwin-compositor marker selects OpenGL through
Zink for KWin 6.8, which removed QPainter. Older packages retain their software compositor.
KWin runs without Gallium's threaded context and without overlay layers. With the threaded context, KWin crashed
uploading windows' shared-memory buffers by reading past their end, and the host shows only a single buffer.
On Android the launcher explicitly selects the KGSL render node; the nested backend can use it
when the host's dmabuf feedback cannot name a DRM device. Games and emulators from the menu go
through droiddeck-gpu, and Steam goes back to the app as a Steam session.
kwin.env pins the KWin version shared by the build and packaging jobs. build-kwin.sh builds that version's
Wayland executable and library on a native ARM64 runner, using a disposable
Arch Linux ARM chroot with every build package signature-checked. It matches the current KWin package
in Arch Linux ARM even when that repository trails KDE's latest release. The source tarball is pinned
by SHA-256 from KDE's official source inventory; patches/0001-respect-nested-desktop-scale.patch
lets Display Settings control the inner desktop scale independently of the outer window size.
It keeps layer sizes, pointer/touch coordinates and the cursor in the same physical pixels.
The behavior is enabled only with DROIDDECK_NESTED_SCALE, which the desktop script supplies.
0002-select-explicit-nested-render-node.patch lets that nested backend use one explicitly
selected KWIN_RENDER_NODES device when host feedback cannot identify it. It does not guess
between GPUs or change normal KWin device selection.
0003-forward-nested-scroll-source.patch passes the host's scroll source, wheel steps and scroll stops
through the nested backend, which upstream leaves as a TODO. Two-finger touch scrolling then reaches
apps as touchpad scrolling, and wheel steps stay whole clicks.
pins/mesa/desc keeps Mesa 26.2.4 and its actual package dependencies ahead of the rolling
repository metadata. Mesa 26.2.5 crashes in Zink shader compilation on Thor with the selected
Turnip driver. mesa.env points at immutable copies of the original 26.2.4 package and signature;
both build jobs verify the Arch Linux ARM signature and pinned SHA-256 as for every other package.
The desktop workflow replaces the same-version kwin_wayland executable and libkwin.so; the rest
comes from the signature-checked Arch packages. desktop-kde.kwin.txt records the source, patch,
executable, library and build package hashes. Corresponding source is
https://download.kde.org/stable/plasma/6.8.2/kwin-6.8.2.tar.xz plus the patch in this repository.
The inventories use .gzip rather than .gz: Android's asset packer expands .gz and strips
its suffix. The shared local/CI runtime payload check verifies the exact APK names and bytes.
Desktop removal uses app/src/main/assets/desktop-removal/, generated by removal-manifests.py
from the checksum-pinned LXQt r1, KDE r1/r2 and emulator r1 archives. KDE candidates are the files
of the desktop applications/themes in seeds.txt (their source package hashes verified against
desktop-kde.packages.txt) plus our overlay. Shared dependencies, fonts, Xwayland and Qt Wayland
remain available to Steam, native apps and emulators. Regenerate the inventories and add the new
version to versions.txt when publishing another desktop pin; unknown versions cannot be removed.
Removal checks file size and SHA-256, or the exact symlink target, before unlinking. Base-runtime
pacman files and emulator bundle paths are protected even when they overlap an application.
It never follows parent symlinks or recursively deletes directories. Home, added apps, custom
files and modified package files stay. A pending marker disables the installed state and allows
retry after interruption. Installing the desktop again repairs its package files and clears it.
The old LXQt applications are cleaned after KDE installation and before the next guest launch on
an already-upgraded runtime, protecting both KDE inventories as well as the runtime and emulators.
Only files owned by lxqt-applications.txt's application packages are candidates; dependencies
stay even when the old runtime's pacman database does not record them. In particular, gamescope
still needs the old package's libseat. The source LXQt application archives are the versions in
the published steamdeck-desktop-r1/desktop.packages.txt; verify their .sig files with
gpgv --keyring tools/desktop-kde/archlinuxarm-builder.gpg and the Build System fingerprint used
by build.sh. Put their filenames in selected.txt in the LXQt cache. sources.json records
their SHA-256 values; file identities still come from the checksum-pinned published desktop.
