Updating
Starting…
The update runs on the display itself, not in this browser. Closing this
window or losing the connection does not stop it — it carries on,
and this page will pick it up again when it can.

Remote access (SSH)
This is the kiosk account password, used for ssh and for
sudo. Turning password login on does not change it.

Admin page password
Saved, but not used yet. Emailing a temporary password needs a server
to send it, which does not exist. Until then Forgot password gives you
the ssh way back in.

Updates
Software
Updates are signed and are checked against that signature before anything is
installed. Installing restarts the browser; a failed update rolls itself back.
Operating system
An OS update can fail, and not every machine can be tested first.
This replaces the whole operating system on this display's spare boot slot
and restarts it. It is designed to fall back on its own — if the new
system does not come up, the next boot returns to the one running now, and
nothing is lost. But hardware varies, and no release can be tested on every
configuration that exists.
Only go ahead if you have a way to recover this
machine physically — a flash drive to reflash it, and access to the
device itself.
Proceed at your own risk.
The OS is signed and checksummed the same way software is. It installs to
the slot this display is not running from, so the system running now
is never written to. The display reboots into the new slot and keeps it only
after it has come up and stayed up; otherwise the next boot returns here.
Update settings
When this is off nothing is installed unless someone presses
Install now above. Turn it off for a display in a shop, where an
update arriving on its own is a surprise to somebody else's business.
latest gets new builds before they are proven. Use it on a bench
machine, not on one a shop depends on. The channel applies to both the
software and the operating system.
Rollback snapshots
What this display was, before each of its last five updates — the
software, the system files an update changes, and the settings. Restoring one
puts all of it back as it was at that moment and reboots. Anything changed
since is undone with it.
They cost almost nothing: each holds every component, but files that did not
change between updates are shared rather than copied.

Audio
Sound follows the screen: the default is the HDMI output with a display on
it. HDMI provides no volume control of its own, so the level here is
applied in software on the way to the card — which also means it is
the only volume control, as the display's own remote will not change it.
A page has to be playing audio for anything to come out; use
Test tone to check the wiring on its own.
Keyboard
The on-screen keyboard for touch displays. It appears when someone touches a
text field on the page being shown.
Key size scales the whole keyboard, keys and text together. It is capped
against the screen height, so on a short display the larger settings still
fit — they stay distinct from each other, but a bigger key on a small
panel is necessarily less big than on a tall one.
Nudge moves the keys away from a dead patch on the touchscreen. Only the keys
move — a press beside them still will not dismiss the keyboard.
Permissions
What the page being shown is allowed to ask this device for.
Screensaver
What the display shows when nobody is using it. A touch brings the page
straight back.
Both times count from the last touch, so
turning the screen off sooner than the screensaver means the screensaver
never appears. With an HDMI-CEC adapter (see Display) the TV is also put
into standby, and woken again the same way. Without one, a television shows
“no signal” while off — try one display first.
Crossing midnight is fine — 18:00 until 06:00 keeps it
out of trading hours.
Startup behaviour
Offline
* While there is no network the device shows its own network page instead of a
“cannot reach the page” error, and loads the real page as soon as
the site answers. After the timeout above it stops waiting and loads the
page from cache instead — a menu board that reboots during an
outage comes back showing the last menu it saw, rather than a diagnostic
screen nobody in the building can act on. Set 0 to wait indefinitely.
While the site is unreachable a 2px red edge marks the screen as offline.
Show the last page when there is no network
With this on, a display that cannot reach its site waits a minute on the
network screen and then shows a picture of the last page it had on screen,
taken while it was working and refreshed hourly. Nothing is written over the
picture — it is the page, as it was, framed by the red offline edge.
The moment the network comes back the real page loads. It applies at boot
and equally in the middle of a run; a display whose page is still rendered
carries on showing it, because a live page beats a photograph of one.
Leave this off for anything people touch, where a stale page that
looks live is worse than a screen that says what is wrong.
Network watchdog
Checks once a minute that this display can still reach its default gateway.
If it cannot, it renews the connection, then re-activates it, then restarts
NetworkManager, and only after all of that has failed does it reboot —
and it will not reboot a machine whose network has never worked since it
started, because that would only repeat the boot it has already had.
A site that is down is not a network fault and never triggers any of
this.
Remote support
Install a ScreenConnect access agent on this display, so it can be reached
from your ScreenConnect console the way your other machines are.
Paste the link exactly as the console gives it, including everything after
the ? — that is what carries the name and the custom
fields, and an agent installed without them arrives unnamed.
Power
This device cannot be switched back on remotely.
Shutting down cuts the admin page, ssh and everything else. Unless somebody
is standing next to the machine and can reach its power button, it stays off
until someone travels to it. If you only need it back in a working state,
use Reboot instead.
