Webconverger heavily uses the notion of
/proc/cmdline to control setup.
Spaces in cmdline
need to be
encodeURI in order not be considered keys themselves. For
developers, startup might better explain how these are used.
Or by using the configuration service form which you need to take a subscription out with Webconverger. The service presents the various options below in a friendly Web form on boot, which are saved on the Web so your values are retained between boots once subscribed.
Your own homepage
You can enter several homepages, which will open in several tabs, separate each
- MACID expands to your network MAC address
- USBID expands to USB serial, for identifying which USB stick was booted - you could conceivably use different USB sticks for a lightweight (but not secure) physical authentication,
USBID_override=is a way to override this value.
- WEBCID expands to Webconverger's identifier
- WEBCVERSION expands to use
git describethe running instance's version
For example Some customers want a way of tracking which kiosks are logging in. These is best accomplished using a keyword MACID. For example the homepage:
Could be expanded to
Changing browser chrome
- chrome=webconverger - this is the default
- chrome=webcnoaddressbar - disable URL bar and search bar, good for controlled access setups
- chrome=webcfullscreen - fullscreen without any chrome
- chrome=neon - fullscreen as used with Neon
- chrome=debug - nightly testing tools, for testing crash recovery etc.
See kiosk for screenshots of the options.

noclean. This is not recommended for deployments, however if some
cases where the machine is used by just one person, this is very convenient for
day to day usage.
Rotate the screen?
To rotate right on all connected screens:
This is computed as running
xrandr --output CONNECTED_DEVICE --rotate right.
For finer control by explicitly naming your CONNECTED_DEVICE, you can use
xrandr=, but then you must discover the exact name of your output device,
which can vary machine to machine.
