PRESENTATIONS_ENABLED, off by default, independent of everything else. A teacher downloads a session in ordinary Chrome and it is on the Presentations screen a few seconds later, ready for the television. No file manager, no import button, no Impress. WHY NOTHING LAUNCHES A DOCUMENT APPLICATION. The brief was to use existing presentation software, so the existing software was tried first, on Debian 13, before any of this was designed. `soffice --show` does start a real fullscreen slideshow — and needs XDG_SESSION_TYPE plus a VCL plugin or it dies with "Failed to open display", shows a splash, opened a "Tip of the Day: 1/225" dialog over the slides, and leaves the Impress editor when the show ends. `okular --presentation` opens THREE windows: the presentation, the ordinary document window behind it, and an information dialog. zathura is not a presenter. pdfpc is the closest and is another dependency with a presenter-console model. Every one of them leaves an application on screen that can open any file on the machine, and none of them knows there is a library to go back to. So LibreOffice converts once, headless, at import, with no window on any screen; poppler renders the pages; the classroom shows the pictures. Measured: 0.34s for a ten-slide PPTX, 0.03s for its ten thumbnails, 0.10s for one slide at 1920px. That is not a new renderer — it is the same engine Impress would have used live — and it means Escape is ours, presenting is instant, and a PDF exported from Google Slides skips the conversion entirely and keeps the appearance Google gave it. THE THREE THINGS KEPT APART. The library thumbnail, the starting slide and the retention clock are independent, because the first slide of a Bible study session is a generic opening shared by every session and the one that names it is usually the second. Quick Look chooses the picture; it does not change where the slideshow starts and it does not count as having presented anything. mark_presented() is called when a slide is actually drawn, not when Present is pressed: an intention is not a presentation, and a viewer that failed to start must not buy another thirty days. IMPORTING. The teacher's download is copied, never moved, renamed or deleted. A file with a .crdownload beside it is still arriving. Wonder Ink's own folder is not looked at. Two downloads of the same name are two presentations, the second titled (2) — found in the lab, where a PDF and a PPTX of one session both came out with the same name because the import being named was excluded from the taken-titles set BY TITLE, and a set holds one copy of a repeated string. Metadata is written saying "importing" before any work, so a reboot mid-conversion leaves a directory the next startup sweeps and imports again. A file that cannot be converted gets a card saying so, offering only Remove, with the teacher's download untouched. Retention: 180 days never presented, 30 days from the last presentation, every presentation starting the thirty over. The cleanup never touches a presentation being shown, never leaves the library directory, and never looks at Downloads. The dock order is unchanged: Presentations is appended after the disc player, so Wonder Ink, the browser and the player keep the places teachers have been reaching for. There is a test for exactly that. classroom-wonderink now asks feature() rather than carrying its own copy of the default, so the panel and the command cannot disagree.

Description: Ekklesia managed classroom environment
|
|
A classroom appliance built on Debian's own Plasma desktop. The room's
|
|
panel, window behaviour, notifications, palette and lockdown are
|
|
configuration for that desktop rather than a shell of our own; what is
|
|
left here is the church's own subject matter — Wonder Ink, the browser,
|
|
the DVD player, the printer, the audio policy and the updater.
|
|
.
|
|
konsole is here for one chord. It is the local recovery route for a
|
|
technical administrator standing at a machine when SSH is not
|
|
available; it is hidden from every application list and reachable only
|
|
by Meta+Ctrl+Alt+Shift+K.
|
|
.
|
|
plasma-widgets-addons is here for one widget: Quick Launch, which is
|
|
the only stock way to put a single launcher on the panel that reads
|
|
/usr/share/applications live. The Icon widget copies the entry into the
|
|
user's home, so an update could never change it.
|
|
.
|
|
python3-gi and gtk-layer-shell are still here because the DVD player
|
|
draws its own loading cover and control bar as layer-shell surfaces.
|
|
They are no longer here for a dock.
|
|
.
|
|
python3-pyqt6.qtwebengine is Wonder Ink. Teachers prepare a lesson across
|
|
several tabs and Chrome cannot be asked for tabs without an address bar,
|
|
so the tab strip is the classroom's and the engine is Debian's Chromium.
|
|
Measured on Debian 13 before it was chosen: H.264 and AAC both decode,
|
|
which is the usual and correct objection to QtWebEngine and is not true
|
|
of this build. Chrome stays exactly where it was, for the ordinary
|
|
browser.
|
|
.
|
|
libreoffice-impress and poppler-utils are Presentations, and neither is
|
|
ever shown to a teacher. LibreOffice runs once per import, headless,
|
|
with no window on any screen, to turn a PPT or PPTX into a PDF; poppler
|
|
turns that PDF into one picture per slide; the classroom's own library
|
|
shows the pictures. Measured before it was chosen: `soffice --show`
|
|
does start a real slideshow and then leaves the Impress editor on
|
|
screen when it ends, and `okular --presentation` opens its own document
|
|
window and an information dialog behind the slides. Neither is
|
|
something a teacher may be left looking at, and converting once at
|
|
import costs 0.34s for a ten-slide deck and nothing at all afterwards.
|
|
libreoffice-gtk3 is deliberately NOT here: nothing interactive runs.
|
|
.
|
|
The fonts are what a Google Slides export asks for. The metric
|
|
compatible families cover the Microsoft names — Liberation for Arial,
|
|
Times New Roman and Courier New, Carlito for Calibri, Caladea for
|
|
Cambria, Croscore for the same three under their Chrome OS names — and
|
|
Roboto, Open Sans, Lato and Montserrat are the web fonts Google Slides
|
|
itself offers. Every one is in Debian main and installs without a
|
|
question. ttf-mscorefonts-installer is deliberately absent: it is in
|
|
contrib, it downloads from a third party at install time and it shows
|
|
an EULA prompt, and an unattended classroom upgrade cannot answer one.
|
|
.
|
|
The Conflicts line is deliberate. A welcome tour, a software centre and
|
|
a phone pairing daemon are all things plasma-desktop recommends and a
|
|
room a teacher walks into should not have.
