[Bug 1574538] Re: BrlTTY not functioning correctly.

[Launchpad Bug Tracker]

This bug was fixed in the package brltty - 5.3.1-2ubuntu2.1

---------------
brltty (5.3.1-2ubuntu2.1) xenial; urgency=medium

  * Update to restore BrlTTY auto/udev start functionality (LP: #1574538)
    - Re-add previously dropped udev rules to the BrlTTY package.
    - Create a systemd service to be used in the udev rules to launch BrlTTy
      when a display is connected.
    - Modify the existing BrlTTy service to be of type simple, so that the
      shell evaluation of /etc/default/brltty works, and the daemon stays
      running.
      - Modify the udev rules file to use the new brltty-udev service
  * Update gbp.conf for xenial branch

Title:
  BrlTTY not functioning correctly.

Status in brltty package in Ubuntu:
  Fix Released
Status in brltty source package in Xenial:
  Fix Released

Bug description:
   affects ubuntu/brltty

  BrlTTy in Ubuntu 16.04 is not currently functional due to some changes
  that were incorrectly introduced during development. The ystemD unit
  to start or stop BrlTTy currently does not function, and Udev does not
  currently start BrlTTY when a USB Braille display is connected.

  Impact:
  These changes only impact the BrlTTy package, and the regression potential is low, because if the systemd unit is incorrect, BrlTTy should not start at all, and by default that is what we want anyway.

  Test case:
  The first part of this test case can be tested by anyone, the second part can only really be verified by someone with a USB Braille display.
  1. Try starting the BrlTTy service using "sudo systemctl start brltty" with BrlTTY 5.3.1-2ubuntu2 installed. BrlTTy should not start, and "systemctl status brltty" should show an error in the log.
  2. Update to BrlTTY 5.3.1-2ubuntu2.1 from xenial-proposed, and try step 1 again. BrlTTy won't start, unless you change RUN_BRLTTY to yes in /etc/default/brltty, but systemctl status brltty should not show any errors.

  Hardware specific test case for USB Braille displays.
  1. Connect a USB Braille display to your computer. Nothing should happen. Disconnect your display again.
  2. Update to BrlTTY 5.3.1-2ubuntu2.1 from xenial-proposed, and re-connect your USB Braille display. BrlTTy should load, and you should see activity on your display.
