Do you have xbrlapi running? (I'm not asking for you to run it, I'm
wondering whether it is already running)

Is the konsole window active when you read on the Braille display?

Hotplug/unplug is not really supported yet indeed. It's usually not
a problem since people don't usually change display model/size when
unplugging/replugging.
