# 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 |

## 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 |

## 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 |
