how to enable braille support in latest live CD builds of Ubuntu?

[Mgr. Janusz Chmiel]

Dear users,

If You will enable button in The Orca preferences menu for enable braille 
support, Orca will work with Your braille display, if Your model is 
supported by Brltty. To enable Brltty support, run
Gnome-terminal
and type sudo brltty.

Then Orca should support your braille display. Brltty is not automatically 
started during booting up to A live CD.

If somebody of us is also suffering because of strange error dialog box 
while intensively working with Espeak and Ubuntu live CD, I Am recommending 
You to install Speechdispatcher as soon as possible when you will install 
Ubuntu on to harddisk. Do not use Espeak, try to use Festival database 
rather. Or use some commercial modules, such as IBM synthesizers or module, 
which is developed by a development team of Oralux project.

Oralux WEB site contained after more than 8 months free version of Gnu/Linux 
based on Knoppix and with several console oriented screen readers, such as 
Speakup or yasr. Emacs has been also included. But now, The developers are 
selling module for Gnome for accessing several speech synthesizers. I did 
not chance to compare their module with Speechdispatcher. Speechdispatcher 
is working very reliably, only with Espeak is causing error. Espeak is 
causing random crashes in Linux, it is not important, if users are using 
Espeak driver for Gnome, or if Screen Reader is using Speechdispatcher for 
controlling Espeak. It is very strange, because Espeak is working very 
reliably aand stably in Windows XP, it sapi5 variants is not causing 
problems. So The cause is probably inside audio subsystems in Linux.

But probably only programmer, who is familiar with Assembler can solve so 
complex issue.

But also users could help by sending error reports.
