[BRLTTY] Issue linking brlapi and orca.

[Didier Spaier]

Hello,

On Slint I start brltty during the booting sequence, then orca when
running startx.

Orca works but I see in its log:
---

Could not initialize BrlTTY:

Traceback (most recent call last):
  File "/usr/lib64/python3.5/site-packages/orca/braille.py", line 1703, in init
    _brlAPI = brlapi.Connection()
  File "brlapi.pyx", line 304, in brlapi.Connection.__init__ (brlapi.auto.c:4813)
brlapi.ConnectionError: couldn't connect to b':0' with key b'polkit+keyfile:/etc/brlapi.key': b'connect: Aucun fichier ou dossier de ce type'
(brlerrno 11, libcerrno 2, gaierrno 0)
Is BRLTTY really running?

brltty is running, /etc/brlapi exists and seems OK:

I would like that users can use a braille terminal on the desktop...

How can I investigate further, and do you need more information?

Thanks in advance for any clue,

Didier
