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.
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 |
Wonder Ink with tabs
0.2.1. A teacher prepares a lesson across several tabs, and none of a browser's other furniture is on the screen.
wonderink-tabs |
[ Lesson ] [ Video ] [ Activity ] — the second and third opened by the lesson itself, one through target=_blank and one through window.open |
wonderink-one-tab |
one tab, and no strip at all: the room looks exactly like the application this replaced |
wonderink-tab-closed |
the middle tab closed; the other two carry on |
wonderink-fullscreen |
a lesson's video over the whole display, panel and tab strip included |
wonderink-after-fullscreen |
and back, maximised above the bar, tabs intact — the bug this caught left the window 200 pixels wide in the corner |
wonderink-context-menu |
the whole of the right-click menu: back, forward, reload, print. No view-source, no save-page, no new window |
wonderink-print-dialog |
a lesson calling window.print(), landing on the room's own Elmer queue |
wonderink-and-browser |
the point of the split, in one picture: Chrome in front with its address bar, Wonder Ink a separate button beside it |
wonderink-autoplay, wonderink-autoplay-control |
the Present-view autoplay failure reproduced and then not reproduced: an unmuted video started by a script with no gesture, blocked at Chrome's default and playing as shipped |
wonderink-packaged |
the packaged shell against the real app.wonderink.org, launched from the .deb on a rebooted machine |
wonderink-disabled |
WONDERINK_ENABLED=false — no lesson button, the browser and the disc player where they were |
Wonder Ink worksheets
0.2.2. A lesson link that downloads a PDF comes back as a tab, and nothing else about the room's locks moves.
pdf-opened |
the worksheet a click downloaded, open as a tab beside the lesson and actually rendered — three pages, not a blank frame |
pdf-page2 |
page 2 of 3: multi-page navigation inside the tab |
pdf-spaces |
Leader Guide, Week 1 (Advent).pdf — spaces, a comma and brackets, through the download and into a tab |
pdf-print |
printing the worksheet, on the room's own Elmer queue |
pdf-closed-then-page |
the worksheet tab closed, the lesson still there and still working, and an ordinary target=_blank tab beside it |
pdf-broken |
HTML the server called .pdf: refused on its contents, with a message, and no blank tab |
pdf-interrupted |
a download that did not finish, saying so. The first version of this said nothing at all |
pdf-guard |
three attempts to reach a local file from the page — a link, a script, and a link to a worksheet that was downloaded but not opened by the shell. All refused |
pdf-dotmenu |
the whole of the PDF viewer's overflow menu, audited: two-page view, annotations, present, properties. No open, no save-as, no external link |
pdf-after-save |
the viewer's own download button: straight to Wonder Ink's directory with a notification, no file chooser and no duplicate tab |
pdf-autoplay-preserved |
the 0.2.1 Present-view autoplay fix, still working on the packaged 0.2.2 |
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. |
The rooms themselves
v2-from-package |
the classroom with the church's own wallpaper and the real Wonder Ink mark |
wonderink-icon |
the same mark as a running application's button |
display-settings |
the hidden display-size dialog, saying that saving needs an administrator |
scale-200, scale-200-notification, scale-200-chrome |
the room at 200%: the panel, a notification card, and the browser, all doubled together |
notification-style |
the notification card on the classroom's own Plasma style |
osd-volume |
Plasma's volume display, which the room keeps |
osd-shellpackage |
the custom one, which rendered correctly and cost the panel |
pc-unreachable, pc-not-configured |
Parent Call telling a broker it cannot reach from one that was never set up |
dvd-absent-bar |
the bar on a machine with no optical drive |
A morning in the rooms
pc-no-mode |
Parent Call ready against a broker with no retained mode — the state that used to say the room was never set up |
pc-bottom-left, pc-200-package |
the card anchored bottom-left at 100% and at 200% |
notif-package-100, notif-package-200 |
the notification card at both scales, from Classroom |
notif-13pt, notif-15pt |
the two font sizes that were weighed for it |
pc-typed-layer |
the card gone: the lab's keyboard tool closes it, which is why typing is still a bench test |
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 |
