[BRLTTY] Brltty woes on Centos 7

[Keith Wessel]

I have debug output. Not sure if this will tell anyone more than it told me,
but let's try.

I got this by adding -l debug -L /brltty.conf to the args environment var in
the brltty at .service that calls the brltty system wrapper.

I get as far as brltty starting then, sometimes it tells me screen not in
text mode, and other times it just hangs on the brltty version number on the
braille display. If I even just kill brltty and let system restar it,
everything's fine. Other than the executable args change, my only other
change to the service unit script is to tell it to start after
alsa-restore.service.

Logs are below.

You'll see at the end of the log, I stopped the service so that I could
capture the logs after the shutdown, but it had several seconds before my
shutdown to start doing something with the display which it didn't do.

Thoughts?

Thanks,
Keith

Subject: RE: [BRLTTY] Brltty woes on Centos 7

Dave,

No, I get a text console on virtual TTY1 when in runlevel 3, so it seems to
be acting sane there.

I figured out why the service unit script that you packaged with brltty
wasn't working, and that was my fault. I was adding to (replacing) the
ExecStart line to add a -q to the start-up. That didn't work since your unit
uses the wrapper setup. I see now, if I want to do that, that I need to add
it to the environment variable that your wrapper uses for the executable
args which need to include the -n switch.

So, now I have my basic service script and your service script ending up at
the same result: they both end up with "screen not in text mode" even when
GDM is not running. And even if I do an alt-F2 to switch to another VT, that
doesn't change. Only way to get it to change is to restart the service.

I did make one change to your system unit script: instead of
Before=sysinit.target, I have After=alsa-restore.service. Otherwise, I don't
have Alsa available when brltty starts it, and it falls back on the beeper
device.

I'm happy to add logging. I notice that, with my basic unit script without
your wrapper, the brltty output all gets captured by journalctl. With the
wrapper, I only get lines about the service starting and stopping. Is there
a way to get the wrapper to send the brltty output to a log of some sort? If
not, I can go back to my simpler service unit script and send you what I'm
seeing in journalctl. If there's any way to get brltty to send more verbose
messages to the console for system to log, I'd also appreciate knowing that.

Given that, I'll collect some info, and we'll see if we can catch this
problem red-handed.

Keith

Does CentOS 7 put X on tty1? If so, I bet it still reserves tty1 for that
even 
when at run level 3.

Please add brltty logging options in your service unit so that we can find
out 
what the problem is from "the horse's mouth".

I doubt it, but who knows. I hate guessing, and much prefer just facts.
