> 3. Run: apt-get install sysvinit-core libpam-elogind-compat brltty-x11
> 
> The brltty-x11 package seems to be necessary since brltty complains
> about missing libraries, and doesn't output in the graphical desktop

> 4. Reboot the system.

> 5. What happens is that brltty runs fine at the text console, but
>    doesn't display output from the lightdm screen. This can be fixed
>    as described above. I have also found that upon logging in as a
>    normal user into the graphical desktop, there is no braille, or
>    speech. Since this isn't an issue in devuan, and since simply
>    getting to the lightdm screen demonstrates the bug I'm describing, I
>    didn't investigate further.
