A real room upgraded to 0.1.45 and came up as stock Debian Plasma with the old Waybar across the top, mako still catching notifications, and a lock screen on an account that has no password. The cause was one line, and it was in the lab: the harness handed the session under test XDG_CONFIG_DIRS by hand, so every result it had ever produced was a result about a machine somebody had already configured. On a machine SDDM starts the session through PAM, PAM does not read /etc/environment.d, and Debian's own plasma-workspace env.sh then set the variable from scratch — so the classroom's settings directory was not in the cascade at all. No layout, no lock policy, no Kiosk restrictions. The settings now arrive the way Plasma delivers them, through a file in /etc/xdg/plasma-workspace/env. Around that: the look and feel is immutable on its own key so a stale profile cannot answer for it; the palette is composed into the package, because naming a colour scheme does not produce one and the dark bar had been coming from a technician's hand; the desktop reset converges another desktop's appearance state and keeps the room's own; and classroom-migrate stops, deactivates and masks the old shell, including the D-Bus activation that brought mako back while the panel was down — found only by killing the panel on a migrated machine. device.conf loses COMPOSITOR and comes off the hyprland channel, which would otherwise have handed the room the experiment back. The lab stops flattering the package: it restarts the machine, lets SDDM actually autologin, and asks a fresh install and a machine upgraded from the Hyprland package the same sixty questions. Both answer identically, twice, and the panel still comes back from eight SIGKILLs. Co-Authored-By: Claude Opus 5 <[email protected]>

# Screenshots from the classroom v2 experiment
|
||
|
||
All 1920×1080, captured with `grim` from a real running session in the
|
||
container lab. See [../classroom-v2-experiment.md](../classroom-v2-experiment.md).
|
||
|
||
## The desktop
|
||
|
||
| | |
|
||
| --- | --- |
|
||
| `v2-idle-desktop` | the idle desktop: the wallpaper, one bar, nothing else |
|
||
| `v2-from-package` | the same desktop, produced by installing the `.deb` on a clean machine |
|
||
| `v2-dark-bar`, `v2-light-bar` | the bar in both themes |
|
||
| `v2-theme-compare` | the two, one above the other |
|
||
| `v2-testpage` | a maximised browser, edge to edge above the bar |
|
||
| `v2-wonderink` | Wonder Ink as an application, in its own profile |
|
||
|
||
## Application state
|
||
|
||
| | |
|
||
| --- | --- |
|
||
| `state-1-closed` | both launchers closed: no indicator |
|
||
| `state-3-behind` | one active (teal), one running behind it (grey) |
|
||
| `state-4-minimized` | minimised — measured identical to *behind*, which is why minimise was removed as a route |
|
||
| `state-5-restored` | back |
|
||
| `v2-both-apps` | both applications, one button each, from the packaged install |
|
||
| `labelled-tasks` | the labelled task manager, evaluated and rejected: it shows changing page titles rather than application names |
|
||
|
||
## Parent Call
|
||
|
||
| | |
|
||
| --- | --- |
|
||
| `pc-icon-vs-notifications` | the Parent Call mark beside Plasma's notification bell — the comparison that decided it |
|
||
| `pc-mark` | the mark at 32, 48 and 64px, beside the two marks it replaced |
|
||
| `pc-panel` | the whole bar: Parent Call left, applications centre, status right |
|
||
| `pc-ready` | the card, ready, in approval mode |
|
||
| `pc-waiting` | waiting for a volunteer to approve |
|
||
| `pc-sent` | *Sent to sanctuary* — never "displayed" |
|
||
| `pc-rejected` | not approved, offering Try again |
|
||
| `pc-off` | the coordinator's mode is off |
|
||
| `pc-nobroker` | the broker is unreachable |
|
||
| `pc-typed` | a name in the field |
|
||
| `icon-candidates-2` | sixteen Breeze person icons at real panel size, none of which meant Parent Call |
|
||
|
||
## DVD
|
||
|
||
| | |
|
||
| --- | --- |
|
||
| `dvd-panel` | DVD in the row with the applications, out of the status area |
|
||
| `dvd-cover` | the DVD launcher's tooltip on the packaged install |
|
||
| `v2-dvd-overlay`, `v2-layershell` | the loading cover: a gtk-layer-shell overlay under KWin |
|
||
|
||
## Windows
|
||
|
||
| | |
|
||
| --- | --- |
|
||
| `v2-secondary-window` | a window a page opened, floating over an untouched browser, with its own close button |
|
||
| `v2-print-dialog` | the system print dialog, over the page that raised it, offering only Elmer |
|
||
| `v2-fullscreen` | fullscreen video: the whole display, panel covered |
|
||
| `v2-layershell` | a gtk-layer-shell overlay under KWin — what the DVD loading cover is made of |
|
||
| `v2-notification-crop` | a notification card, top right |
|
||
|
||
## Administration
|
||
|
||
| | |
|
||
| --- | --- |
|
||
| `admin-terminal` | the maintenance terminal, opened by its chord's action |
|
||
| `admin-terminal-bar` | the bar with the terminal open, and after closing it: a task button while it runs, no launcher ever |
|
||
|
||
## Reliability and lockdown
|
||
|
||
| | |
|
||
| --- | --- |
|
||
| `recovery-after-8-kills` | the panel after eight consecutive SIGKILLs |
|
||
| `recovery-after-kwin-kill` | the session after KWin was killed twice; the application window survived |
|
||
| `recover-panel` | the bar rebuilt from the layout script after its configuration was deleted |
|
||
| `lock-desktop-rmb` | right-clicking the wallpaper: no menu |
|
||
| `lock-panel-rmb` | right-clicking the bar: no menu |
|
||
| `lock-krunner` | KRunner asked for, and not there |
|
||
|
||
## The migration
|
||
|
||
| | |
|
||
| --- | --- |
|
||
| `migration-before` | what a real room got when it upgraded: stock Debian Plasma, kickoff, a pager, a system tray, the Debian wallpaper. Reproduced in the lab by taking one line out of the harness. |
|
||
| `migration-after` | the same machine after the fix — a Hyprland-era install, upgraded, rebooted |
|
||
| `migration-after-bar` | its bar, at the size a teacher sees it |
|
||
| `migration-parent-call` | Parent Call on the migrated machine, saying it cannot reach the church network rather than pretending it can |
|
||
| `theme-light-live`, `theme-light-after-logout` | the room's own light theme, and the same room after logging out and back in. The first attempt at this pass lost it. |
|
||
|
||
## Failures, kept
|
||
|
||
| | |
|
||
| --- | --- |
|
||
| — | keyboard injection never reached the nested session, so every interaction in this experiment was driven by the pointer. It is why Parent Call has never had a real key pressed into it, and why that is the first bench test. |
|
||
| `m-closed`, `m-minimized` | the pair whose pixels were sampled to show that Plasma draws minimised and closed differently, but minimised and *behind* the same |
