1 +# neiam-device
2 +
3 +Branding packages for neiam devices, published as `.deb` and `.rpm`
4 +through the same pipeline as ppl.
5 +
6 +| Package | Installs to |
7 +|------------------------|--------------------------------------|
8 +| `plymouth-theme-neiam` | `/usr/share/plymouth/themes/neiam/` |
9 +| `sddm-theme-neiam` | `/usr/share/sddm/themes/neiam/` |
10 +
11 +Both are architecture-independent (`all` / `noarch`).
12 +
13 +## Images
14 +
15 +Every background is rendered per resolution rather than scaled from
16 +one master, and each theme picks the render that best fits the screen
17 +(matching aspect ratio first, then least scaling, preferring to shrink):
18 +
19 + plymouth/theme/background-<W>x<H>.png
20 + sddm/theme/backgrounds/<W>x<H>.png
21 +
22 +at 1280x800, 1366x768, 1920x1080, 1920x1200, 2560x1440, 2560x1600 and
23 +3840x2160.
24 +
25 +The files committed now are stand-ins: solid `#651d1d` with a `#fef3c7`
26 +moire fading out into it. Blender renders replace them by overwriting
27 +the file at the same path; nothing else needs to change.
28 +
29 + tools/standins.py # write any missing stand-ins (needs numpy, Pillow)
30 + tools/standins.py --force # rewrite them all
31 + tools/standins.py --check # every image present at its size? (CI runs this)
32 +
33 +Adding or dropping a resolution means editing three lists together:
34 +`RESOLUTIONS` in `tools/standins.py`, the `bg_*` table in
35 +`plymouth/theme/neiam.script`, and `backgrounds` in
36 +`sddm/theme/theme.conf`.
37 +
38 +The Plymouth theme is copied into the initramfs, so every render there
39 +adds to its size.
40 +
41 +## Enabling
42 +
43 +Installing a package does not switch to its theme:
44 +
45 + # Plymouth (rebuilds the initramfs)
46 + sudo plymouth-set-default-theme -R neiam # Fedora / openSUSE
47 + sudo update-alternatives --set default.plymouth \
48 + /usr/share/plymouth/themes/neiam/neiam.plymouth \
49 + && sudo update-initramfs -u # Debian / Ubuntu
50 +
51 + # SDDM
52 + printf '[Theme]\nCurrent=neiam\n' | sudo tee /etc/sddm.conf.d/neiam.conf
53 +
54 +Try the login screen without switching to it:
55 +
56 + sddm-greeter-qt6 --test-mode --theme sddm/theme
57 +
58 +## Building
59 +
60 +The packages are data-only cargo crates so that `cargo-deb` and
61 +`cargo-generate-rpm` apply as they do for ppl:
62 +
63 + cargo deb -p plymouth-theme-neiam --no-build --no-strip
64 + cargo deb -p sddm-theme-neiam --no-build --no-strip
65 + tools/deb-arch-all.sh target/debian/*.deb
66 + cargo generate-rpm -p plymouth -a noarch
67 + cargo generate-rpm -p sddm -a noarch
68 +
69 +`cargo-deb` can't mark a package `Architecture: all`, so
70 +`tools/deb-arch-all.sh` rewrites that one control field afterwards.
71 +
72 +CI (`.github/workflows/package.yml`) does the above on every push,
73 +stamping `+dev.<timestamp>` onto branch builds and publishing to the
74 +forge's deb and rpm registries. Releases use `./release.sh` as in ppl:
75 +a `v*` tag publishes the bare version.
