neiam-device

Branding packages for neiam devices, published as .deb and .rpm through the same pipeline as ppl.

Package	Installs to
plymouth-theme-neiam	/usr/share/plymouth/themes/neiam/
sddm-theme-neiam	/usr/share/sddm/themes/neiam/
plasma-wallpaper-neiam	/usr/share/wallpapers/neiam/ (desktop and lock screen)
plasma-splash-neiam	/usr/share/plasma/look-and-feel/org.neiam.desktop/ (splash after login)

Both are architecture-independent (all / noarch).

Images

Every background is rendered per resolution rather than scaled from one master, and each theme picks the render that best fits the screen (matching aspect ratio first, then least scaling, preferring to shrink):

plymouth/theme/background-<W>x<H>.png
sddm/theme/backgrounds/<W>x<H>.png
wallpaper/theme/contents/images/<W>x<H>.png

at 1280x800, 1366x768, 1920x1080, 1920x1200, 2560x1440, 2560x1600 and 3840x2160.

The files committed now are stand-ins: solid #651d1d with a #fef3c7 moire fading out into it. Blender renders replace them by overwriting the file at the same path; nothing else needs to change.

tools/standins.py           # write any missing stand-ins (needs numpy, Pillow)
tools/standins.py --force   # rewrite them all
tools/standins.py --check   # every image present at its size? (CI runs this)

The Plasma splash has no images of its own: it shows the installed wallpaper package’s, so login hands off to a desktop using that wallpaper without a visible change.

Adding or dropping a resolution means editing four lists together: RESOLUTIONS in tools/standins.py, the bg_* table in plymouth/theme/neiam.script, backgrounds in sddm/theme/theme.conf, and backgrounds in splash/theme/contents/splash/Splash.qml. Plasma finds the wallpaper’s sizes by itself.

The Plymouth theme is copied into the initramfs, so every render there adds to its size.

Enabling

Installing a package does not switch to its theme:

# Plymouth (rebuilds the initramfs)
sudo plymouth-set-default-theme -R neiam                 # Fedora / openSUSE
sudo update-alternatives --set default.plymouth \
    /usr/share/plymouth/themes/neiam/neiam.plymouth \
    && sudo update-initramfs -u                          # Debian / Ubuntu

# SDDM
printf '[Theme]\nCurrent=neiam\n' | sudo tee /etc/sddm.conf.d/neiam.conf

Per user, in System Settings: the wallpaper under Wallpaper and Screen Locking → Appearance, the splash under Splash Screen (or plasma-apply-wallpaperimage /usr/share/wallpapers/neiam and kwriteconfig6 --file ksplashrc --group KSplash --key Theme org.neiam.desktop).

KDE’s settings show sddm/theme/preview.png and splash/theme/contents/previews/*.png; re-render them after changing the themes or their art:

QT_QPA_PLATFORM=offscreen qml6 tools/sddm-preview.qml
QT_QPA_PLATFORM=offscreen qml6 tools/splash-preview.qml

Try the login screen and splash without switching to them:

sddm-greeter-qt6 --test-mode --theme sddm/theme
ksplashqml --test --window splash/theme

Building

The packages are data-only cargo crates so that cargo-deb and cargo-generate-rpm apply as they do for ppl:

cargo deb -p plymouth-theme-neiam --no-build --no-strip
cargo deb -p sddm-theme-neiam --no-build --no-strip
cargo deb -p plasma-wallpaper-neiam --no-build --no-strip
cargo deb -p plasma-splash-neiam --no-build --no-strip
tools/deb-fixup.sh target/debian/*.deb
cargo generate-rpm -p plymouth -a noarch
cargo generate-rpm -p sddm -a noarch
cargo generate-rpm -p wallpaper -a noarch
cargo generate-rpm -p splash -a noarch

cargo-deb can’t mark a package Architecture: all and writes an empty Depends: for packages with nothing to link, so tools/deb-fixup.sh corrects the control file afterwards.

CI (.github/workflows/package.yml) does the above on every push, stamping +dev.<timestamp> onto branch builds and publishing to the forge’s deb and rpm registries. Releases use ./release.sh as in ppl: a v* tag publishes the bare version.
