[BRLTTY] BRLTTY blocked on console while Orca is running on Wayland

[Elias Oltmanns]

Hi there,

Manjaro has switched to GNOME 49 without support for Xorg recently. The
Linux console is my favourite working environment but I had to get a
working GUI back, too. After some research, I managed to launch GNOME
and Orca on Wayland from the console.

Unfortunately, the main BRLTTY process can (or does) not claim the
braille device while Orca is running with braille support enabled. Here
are the steps I take to reproduce the problem:
- Start on tty1 in text mode.
- BRLTTY is running and controls braille device on all terminals in text
  mode (as expected).
- Run gnome-session to start the GUI including Orca wtih braille support
  enabled.
- Braille device responds to Orca now (as expected).
- Switch to tty2 in text mode.
- The braille device still shows Orcas output and I can even use the
  keys on the device to navigate that output. Nevertheless, tty2 is the
  active terminal for the rest of the system and keyboard input goes
  there, for instance.

Braille access to tty2 in text mode is restored when I disable braille
support in Orca or terimanet the GNOME session entirely. Interestingly,
in a GNOME terminal session with Orcas braille support disabled, I can
start
    brltty -x a2 -b ba -r
in order to get braille support in the terminal session and still have
braille support when switching to the text console on tty2. This way,
however, I am without braille support in GUI applications, so I would
like to fix that.

Do you have any idea what might be going wrong and how to investigate
and fix it?

Thanks in advance and best wishes,

Elias
