Comment 1 for bug 83939

Mike, I'll likely bet that your display is USB, and you have Brltty configured to start via the init script etc. Brltty now ships with udev rules to automatically start brltty if a usb Braille device is found, so thats probably the second occurrance of brltty accounted for.

To be sure of this, try re-adding the exit line that used to be in /etc/init.d/brltty and see if that makes a difference.

As for Orca, I'll give that a test shortly, and see if I get the same behavior.
