Hi,
I tried the following now:
* Replaced my re-built brltty package with the package from extra (with
a2 flag set in PKGBUILD).
* Made some changes in the "general screen settings" section of
/etc/brltty.conf which was commented out completely before, i.e.
specified at-spi as screen driver (s. above).
...with the following result:
* The braille display is recognized at startup (brltty logo displayed).
* Message "no screen" is displayed as long as text-only console is used.
* Orca works with braille, but some keys of my braille display (Handy
Tech Braille Star 40) don't work, i.e. keys to move the cursor up and
down. I had this problem in the past with older versions of gnome2.x
and orca, it has gone before 3.x as I remember.
* When switching back to text console, nothing happens on braille display.
Here is the /etc/brltty.conf file I used. Originally, the whole "general
screen settings" section was commented out and I have no idea which
default settings, i.e. which screen driver has been used in the past
(before the a2 flag in PKGBUILD was introduced), but it seems to me that
not at-spiX (how would orca and braille work in this case)?. Maybe I
ignored something else in the "general screen settings" section?
- ---begin config file
# This is a configuration file template for the BRLTTY application.
# Uncomment those entries which apply to your personal needs and system
# requirements.
# BRLTTY expects to find its configuration file in "/etc/brltty.conf"
# (can be overridden with the -f [--configuration-file=] option).
# If it doesn't exist, then BRLTTY silently continues but may require
# that certain command line options be explicitly supplied.
# Blank lines are ignored. The character '#', anywhere on a line,
# initiates a comment; all characters from it to the end of that line
# are ignored.
# Each configuration entry consists of a keyword followed by its operand.
# An arbitrary amount of white space, (blanks and/or tabs), may occur
# before the keyword, as well as before and after the operand. Keyword
# processing is not case sensitive. Examples of valid entries are:
#
# Braille-Driver pm # Papenmeier braille displays.
# braille-device serial:ttyS0 # The first serial device.
# SPEECH-DRIVER fv # The Festival Text to Speech System.
# The default settings given within the following descriptions assume no
# special build options (see "./configure --help" in the top-level

# The braille-device directive specifies the device to which the braille
# display is connected. The generic syntax is type:device. The device
# type is optional, and, for backward compatibility, defaults to serial.
# The following devices are supported (brackets indicate optionality):
# serial:path (relative paths are anchored at "/dev")
# usb:[serial-number]
# bluetooth:address
# If not specified, "usb:" will be used.
# (can be overridden with the -d [--braille-device=] option)

#braille-device usb:nnnnn # Specific USB device by serial number.
#braille-device bluetooth:xx:xx:xx:xx:xx:xx # Specific bluetooth device
by address.
#
# NOTE: If the device is connected through a serial-to-USB adapter,
# braille-device usb: will not work, braille-device has to be set to
something
# like serial:ttyUSB0, see the kernel messages on device plug to get the
exact
# device name.
# The release-device directive specifies whether or not the device to
which the
# braille display is connected is to be released when the current
screen or
# window can't be read by BRLTTY. If not specified, "on" will be used on
Windows
# platforms and "off" will be used on all other platforms.
# (can be overridden with the -r [--release-device] option)
