Hello list, 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 editing the conf-file, a simple "sudo touch /etc/brlapi.key" and "sudo chmod 0644 /etc/brlapi.key". Kind regards, Frans-Willem Post On 23-07-18 10:36, John Covici wrote:
You might want to make sure you have a line in your /etc/brltty.conf like this: api-parameters Auth=keyfile:/etc/brlapi.key # Require authentication key and create the keyfile and give it 0644 permissions and put some data in the file -- I am not sure it matters what the data is.

On text console TTYs (Ctrl+Alt+F3, +F4 etc) it does work. I have replayed this upgrade in a VM with a clean install of Ubuntu. The problem begins as soon as the system reboots after the policykit update. I've filed a bug: https://bugs.launchpad.net/ubuntu/+source/brltty/+bug/1782320 These are the error messages taken from /var/log/syslog: brltty[2635]: polkit_authority_check_authorization_sync error 11: Resource temporarily unavailable. brltty[2635]: brltty: polkit_authority_check_authorization_sync error 11: Resource temporarily unavailable. This is continuous, while the display reads "Screen not in text mode". Ultimately, the display turns itself off (or BrlTTY does this, I don't know). Can someone help me get the display back up under GNOME (i.e. under X)?
