Thanks to a member of the BrlTTY mailing list, my problem is solved. It seems that the default authorization of BrltTTY under Ubuntu was no longer working. Providing it with a dummy key-file was enough to get it back to work - instantly.
The display came back to life immediately after these steps: - edit /etc/brltty.conf, uncomment the line "api-parameters Auth=keyfile:/etc/brlapi.key" - sudo touch /etc/brlapi.key - sudo chmod 0644 /etc/brlapi.key For me, the issue is solved. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782320 Title: Braille display inoperable in GUI since polkit-update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/brltty/+bug/1782320/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
