Something that people may not know is that brltty recognize kernel command line option brltty=foo as "use driver foo", and this overrides config file (and maybe even daemon option). As a result, ubuntu indeed shouldn't use brltty=ask, but something else (braille=ask for instance)
BTW, if people want to test brltty support (even if they don't have hardware), just use the tt driver (TTY) with a serial port and plug a minicom on the serial device (or use qemu's -serial stdio option) -- Brltty doesn't properly load when attempting to use serial braille display on live CD. https://launchpad.net/bugs/91894 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
