Bug#1116525: Trying to run brltty

[Roland Clobus]

Hello Samuel,

I'm struggling to run brltty properly.

As I understand it, there are 2 scenarios:
* Running brltty on the host, while running the Debian installer in qemu


I'm looking at the documentation:
https://wiki.debian.org/DebianInstaller/Accessibility

* brltty is (nowadays?) not found in /sbin, but in /usr/bin
* Starting brltty as a non-root user (roland):

$ brltty -b xw -x no -A auth=none,host=127.0.0.1:1
BRLTTY 6.8 rev BRLTTY-6.8 [https://brltty.app/]
brltty: can't isolate namespaces
brltty: executing as the invoking user: roland
brltty: can't set supplementary groups
brltty: group not joined: 0(root)
brltty: group not joined: 5(tty)
brltty: group not joined: 20(dialout)
brltty: group not joined: 133(input)








While running this, I get many lines with:
baum: brlapi__enterTtyMode: Can't determine tty number

And after the installation has finished:


I've then enable networking and installed brltty-x11.

Within the installed system, lsusb shows the braille device:


So unfortunately, I'm unable to test braille support at this moment.

With kind regards,
Roland

* Running brltty on the installed live system, which was installed without network cards available. brltty: required capability not granted: cap_sys_admin (for injecting input characters typed on a braille device) brltty: required capability not granted: cap_sys_tty_config (for playing alert tunes via the built-in PC speaker) brltty: required capability not granted: cap_mknod (for creating needed but missing special device files) Do I need additional group memberships to make this work properly, or should I run as root? The brltty window has the content 'no screen', both in regular letters and in braille. I ran the following command for the installation (installer with speech synthesis): BRLAPI_HOST=127.0.0.1:1 kvm -usbdevice braille -cdrom debian-live-13.1.0-amd64-gnome.iso -hda scratch_hd.qcow2 -m 8192 -boot d -device ac97 -net none BRLAPI_HOST=127.0.0.1:1 kvm -usbdevice braille -hda scratch_hd.qcow2 -m 8192 -device ac97 -net none Bus 001 Device 002: ID 0403:fe72 Future Technology Devices International, Ltd QEMU USB BAUM BRAILLE
