As a reminder, bug reporters are *not* Cc-ed when you mail only [email protected], so I never got that mail... > As I understand it, there are 2 scenarios: > * Running brltty on the host, while running the Debian installer in qemu > * Running brltty on the installed live system, which was installed > without network cards available. It's not two scenarios, it's the two things that are needed. The first one is just a braille device emulator, while the second one is the normal brltty, that will connect to the first through the usb emulation. > 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) > 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? That's all just harmless warnings. > The brltty window has the content 'no screen', both in regular letters > and in braille. That's expected since we passed -x no to say we don't want a screen reader. > 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 > > While running this, I get many lines with: baum: brlapi__enterTtyMode: Can't > determine tty number That's the real issue. Which terminal did you run it in? I now notice that gnome-terminal doesn't expose WINDOWID any more :((( You can circumvent it by passing -display sdl to qemu, as the sdl frontend knows how to get a proper window ID. I have now added that information on the wiki. Samuel
