Orca braille feature not working in Ubuntu 12.10?

[Hammer Attila]

Hy,

I downloaded yesterday with Ubuntu 12.10 current daily live CD. I have 
got an Alva Satelite 570 braille display. Prewious Ubuntu 12.04.1 live 
CD wonderful detecting this braille display, launch proper with Brltty 
service, and possible using Orca braille support with native Brltty or 
Liblouis contracted braille.
I surprised little after I enabled in Orca preferences dialog the 
braille page with braille support and click Ok button. Unfortunately, 
Orca native Brltty support possible not working in Ubuntu 12.10? After I 
click OK button, nothing changed. If I restart Orca, braille still not 
working.
I verifyed in console working Brltty or not. I switch console with 
ALT+F1 key combination. If Brltty right running, I see console related 
messages. In Ubuntu 12.10 I see "screen not in text mode" message.
Any braille user possible confirming this?

If I using an Ubuntu 12.04.1 live CD, Brltty right starting if my USB 
braille display is connected.

In Ubuntu Quantal packaged following Brltty version:
4.4-5ubuntu3
