[BRLTTY] Yet another way to break brltty

>Or at least make it unusable.

No, brltty isn't breakable or unusable as you're assuming and seem to be 
experiencing. I'm suspecting that, in some way, you haven't built or installed 
it correctly. We'll figure it out.

By the way: I'm using your experiences as idea generators to make things easier 
for those who may not be doing things in the expected way. For example, I've 
started to put together a set of systemd device allow rules so that brltty can 
eventually be run non-root. It'd still assume systemd service management, 
though, as opposed to direct invocation.

And it still does. I just checked to be absolutely sure.

>The third option now shows nothing but full cells (all 8 dots) instead of 
>contracted. 

This must mean that your contraction table hasn't been correctly installed. 
Perhaps all of your tables haven't been correctly installed. Either that, or 
your contraction table definition is an absolute path to the wrong place.

Okay. I just looked in the huge log you sent earlier. You've specified the 
latex-access contraction table, and it's seeing it as a regular, rather than as 
an executable, table. Please check that it's executable.

>I selected this option to see what would happen. Now my display shows nothing 
>but all 8 dots, for everything, forever. I can see the "Preferences menu" 
>message but beyond that everything is dotted out. What is this feature for? 

Of course it's not a feature. 

I've just checked a little further. Even though the latex-access contraction 
table is executable within the repository, it's not being installed such that 
it's executable. I'll look into fixing this. Meanwhile, please make your copy 
executable by doing:

   chmod a+rx /etc/brltty/Contraction/latex-access.ctb

latex-access is the only executable contraction table that we have, and you 
happen to be the first person who's had this problem. We'll fix it.
