[BRLTTY] Braille display inoperable in GUI since polkit-update

[John Covici]

You might want to make sure you have a line in your /etc/brltty.conf
like this:
api-parameters Auth=keyfile:/etc/brlapi.key  # Require authentication
key
and create the keyfile and give it 0644 permissions and put some data
in the file -- I am not sure it matters what the data is.
