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]>

# The classroom's power button does nothing.

# A teacher reaching behind a television for a cable, a child leaning on
|
|
# the tower, a volunteer tidying the room: none of those should be able to
|
|
# take the computer down in the middle of a Sunday morning. Recovering a
|
|
# room that has been switched off needs somebody who knows where the
|
|
# button is, which is exactly the person who is not there.
|
|
#
|
|
# This is one of two layers, and both are needed. While a graphical
|
|
# session is running, PowerDevil takes logind's handle-power-key
|
|
# inhibitor and acts on the button itself, so logind alone would be
|
|
# ignored — see the classroom's powermanagementprofilesrc for the other
|
|
# half. This layer is what covers the machine before the session starts,
|
|
# after it ends, and if PowerDevil is not running at all.
|
|
#
|
|
# Holding the button for several seconds still cuts the power. That is
|
|
# the firmware doing it, below any operating system, and it is left alone
|
|
# on purpose: it is the only recovery a person standing at a wedged
|
|
# machine has.
