Packages often deviate from upstream configurations, but each deviation can
be more work for distro
packagers, or less work if they are able to recycle an existing .spec.  A
basic problem is that distro
packagers can't possibly test all use cases for a complicated package like
brltty (the remote sensing
applications I use are impossible to package due to reliance on particular
configurations of
third party libraries like hdf4, hdf5, and netcdf4 that vary across
distros).

The docs mention two groups: brltty and brlapi.  I don't expect Fedora
packages to keep the britty.com rpm
mechanisms, and it isn't a surprise to me that some steps get overlooked
(low hanging fruit for Murphy's law)..

But a step too far for inexperienced users managing their own system.

Dear George, “I live in a world that includes Ubuntu, macOS,  and Windows.  Organizations I workwith use CentOS for large scale batch processing but make the users run Windows, soanything that makes it easier for developers to support multiple platforms is of interest.”Yeah, for me is windows as well, since a lot of programs I use, lambda for example, an accessible math editor, is packaged only for windows. But still, I wanna be able to use Linux for most of my work.Since I’ve installed Linux on a Mac, I have experience with Mac OS too, and it’s quite good in my opinion, also accessible.And, since I got started with ubuntu when starting with Linux, I have experience with that too.“Thanks for checking the Fedora rpms.   It looks like visually impaired users will be encountering lots of changes for Wayland and the sound system going forward.”Heh, heh, heh! That’s all I have to say.Just for the fun of it, I upgraded to F34 before having to do a fresh reinstall, and well, the changes to the sound system are not fun.Pipewire I don’t think does even work, from what I could gather from the braille display, since orca, after log in, was not speaking at all.So, with the help of the braille display, I opened firefox, and navigated to some random YouTube video, and nothing plaied. So for now, audio is a big nono, and accessibility is as well.Hopefully they’ll fix it before April.Best regards.Francisco.From: George N.

Seems to me that changelog only applies to the packages supplied by britty.com.
At britty.com there includes a brltty-systemd-6.3-1.noarch.rpm which is what I 
believe is being
referenced in the changelog comment.

Systemd changes:
  The brlapi group is created during boot if it doesn't already exist.

The brltty service file included with that rpm has a size of 2827. Fedora's 
service file has a size of
217 and comes with brltty-6.3-1.fc34.

The britty.service supplied by britty.com includes a call to 
/usr/libexec/brltty/systemd-wrapper.
That file doesn't exist in the Fedora world.  So, I don't think documentation 
on the brltty site is a
faithful mirror of things included in Fedora.

I don't understand your question about what creates the group.  The britty.com 
rpms don't contain any scripts.
I've already mentioned that the packages supplied by Fedora include a PREIN 
script that creates the group.

One of the advantages of systemd was supposed to be collecting some of the

systemd files.

The Changelog at britty.com for the 6.3 release says
the systemd component was changed to create the brlapi group if it
doesn't exist, so the same functionality as the script.  Maybe the change
was a response to systems that failed to run the install script.   What
creates the brltty group?

I live in a world that includes Ubuntu, macOS,  and Windows.  Organizations
I work
with use CentOS for large scale batch processing but make the users run
Windows, so
anything that makes it easier for developers to support multiple platforms
is of interest.

Thanks for checking the Fedora rpms.   It looks like visually impaired
users will be
encountering lots of changes for Wayland and the sound system going forward.

I don't known anything about Debian.  But I did check the rpm's from F27 and 
the rpm's from
brltty.com.

The rpm's from britty.com do not contain any scripts.

The rpm's from Fedora do contain scripts and the script which creates the group 
is within
the brlapi rpm and the group is created in the "normal" way.  I don't know what 
you mean
by "creating groups with systemd".

The PREIN script contains

getent group brlapi >/dev/null || groupadd -r brlapi >/dev/null

Additionally F34 will have brltty-6.3-1.fc34 which includes brlapi-0.8.2-1.fc34 
and that contains
the same PREIN script.

Yes -- that is what how I understood the situation.   The brltty devs
maintain Debian and
RedHat packages with different post-install while creating groups with
systemd should
work across distros (but the step to move the creation so systemd is easily
overlooked, and
may not be noticed for a while since most installs will be upgrades rather
than fresh installs).

For many users, the need to create and join groups falls in the category of
unknown
unknowns.

In the event that what I wrote was ambiguous I just want to clarify what I was 
attempting to say.

Installs of brlapi and brltty packaged by fedora (as early as F27) resulted in 
the creation of the
brlapi group.  It did not add any users to that group.  I don't have the F27 
rpm to examine.
However, the group creation was most likely done by a post installation script 
the packager
included in the rpm.

Just like, for example wireshark, it is up to someone with admin/root 
privileges to add users
to a given group.

FWIW, the "groups" command can be used to list the current groups of a user's 
current shell
environment.

Glad it is working.  I'm not sure how dnf would be able to add a user to
those groups or flag the need to do that.   There are other systems that
create groups and it is up to the "administrator" to add the appropriate
users to the appropriate groups.
There is an opportunity to assign users to groups when creating a user
account, but if the user is also the administrator the groups won't have
been created with a normal install.  Ideally there would be an installer
for blind users, but the variety of use cases is (using braille or speech,
different levels of vision, different assistive devices).  Kickstart is
used to automate installations so could be useful once you know which
packages are needed.

Dear Ed,


I found another way, really randomly: I just needed to add myself to the

it does, maybe because i added myself to brltty as well, thanks for

Dear George and Edd,


Thanks for all the suggestions, I've been reading them, but only now I 
got around to installing version 6.3 of BRLTTY.


I installed every rpm eccept the source, cause, and brlapi.

I kind of think I do need brlapi, but when i try to install it with the 
rpm -i command as sudoer, this happens.

brlapi-0.8.0-11.fc33.1.x86_64


Now, i hope to goodness that i don't have to remove brlapi as a hole 
package, cause the first time i tried that it broke pretty bad, and i 
had to reinstall the entire Fedora system to get everything back in 
order: what happened was, speech wasn't a thing anymore. when removing 
brlapi, in fact, a lot of dependencies were removed too, and i think 
that's what caused it. so, how can i install the newer package 
overriding the error that is written above?


Another thing:

I'm seriously glad i switched to fedora.

I heard and saw online that Fedora was a distro with a strong community, 
but seeing it and experiencing it is an absolutely different thing.


So what I'm saying is, thank you everyone, for just welcoming me with 
open arms and rying your absolute best to answer my question.


it's just hard to find such a community, at least, for me it has been.

Best regards.

Francisco.

That doesn't seem to be quite an accurate statement.

I just checked dnf history and apparently it was installed on my 
system on 12/26/2017.  That
was when Fedora 27 was around.  It seems to have been pulled in by 
some other package.
But, I've never had a need to use it.  So, I'm certain I never added 
the group manually.


brlapi-0.6.6-8.fc27 and brltty-5.5-8.fc27 were installed at that time.

The only other dnf actions on the package has been during updates and 
system upgrades.

Apparently the Fedora package doesn't create a group needed by brltty (a
capability added in 6.3).
The online docs mention a group with user-defined name (for access to a
"key") as well as setgid.
I'm not sure if there is more than one group needed, or whether there are
other constraints (values
less than 1000) so it is best to get groups set up by systemd.

The Fedora package may have been tested and only used system that already
had the group(s) defined.

The brltty RPM has the "linux-screen" driver which provides the simplest
useful configuration so a good
starting point.

I assume whoever maintains the Fedora rpm can only test a small subset of
the available devices.

I also notice the brltty-xw package (XWindow driver for BRLTTY) but not

It appears to be needed to use orca for braille display of X.org text

You should not need the source rpm.  Try "dnf install

error, post the error message here for advice.  There could be issues with a

Just wondering.

You're suggesting the OP download and install brltty from brltty.com why?  Has 
the fedora supplied
version proven not to work?

I also notice that the number of packages supplied by brltty.com for each 
release are different than
that supplied in the fedora repo.  Could that be significant in any way?

I also notice the brltty-xw package (XWindow driver for BRLTTY) but not sure 
what functionality or
purpose it serves.  Or what, if any, problems would arise if not installed.

There are no dumb questions.   Linux has so many use cases and complexities
that everyone runs into

I see that Fedora Linux 34 will contain the 6.3 release, by the way.

In the meantime, I suggest to use

sudo groupadd brlapi

to create a new group rather than editing with nano, and

sudo gpasswd brlapi -a $USER

to add yourself to that group. You will then need to log out and in again
for that to take effect.

By this error you mean starting the brltty service?

A few things

I find it odd that the line wasn't in /etc/group to being with as that is 
normally done when the package is
installed.  Anyway

It is possible the group number needs to be lower than 1000.  I forgot to 
mention that is normally the
case that system processes use groups lower than that.

You may have to reboot the system for the group to be recognized by system 
processes.

Well

You can add the line

brlapi:x:975:

to the file.

But, just make sure that 975 is unique.

Or, you can use the "groupadd" command.

To add your your user to the group you can just append your username 
to the end of the line.


brlapi:x:975:yourusername

Use the "groups" command to see what groups you currently belong to.  
It may be best to

logout/login to make sure your now a part of that group.

Do you have an entry for brlapi in your /etc/group?

I do, and if I start the service I don't get the error you note.

Also, it may be possible that with that line you'd need to add your 
user to be in that group.

Do you have an entry for brlapi in your /etc/group?

I do, and if I start the service I don't get the error you note.

Also, it may be possible that with that line you'd need to add your user to be 
in that group.

Dear Ed,


I'll paste below the output that the command you suggested gave me, 
there's something disturbing indeed in that command, that I didn't try 
till you suggested it.



systemctl status brltty

This error persisted so i didn't copy it as many times as it output itself.

the output below, instead, is the output that is given when i type xbrlapi

Thanks again for all the help.
Best regards.
Francisco.

xbrlapi

even with admin wrights, an error about not beeing able to establish

Any suggestions?



Glad the link helped.

Again, not knowing anything, what is the output of the command

My experience with a blind user was decades ago, but at that time the
available software did not support graphical
screens.  From https://github.com/brltty/brltty:

"BRLTTY is a background process (daemon) providing access to the Linux/Unix
console (when in text mode) for a blind person using a refreshable braille
display."

You may be used to switching to a console using , but in
Fedora that gets you the GUI login like
 in other distros.  You can use  for a text
console.

I don't know anything about brltty.  But, I did find this and wonder if it may 
have some helpful information

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/using_the_desktop_environment_in_rhel_8/configuring-desktop-environment-for-accessibility_using-the-desktop-environment-in-rhel-8

Also, I don't often use Workstation/GNOME.  But I know somethings may not work 
as well running under
Wayland.  Have you tried logging into a GNOME Xorg session?

Thanks for the hint. I've been an XFCE fan for a few years, using it on my 
low-specs machines since 3.x. But right now I just like the idea of a full-
blown desktop, where I can "Save as..." and directly SSH into a remote PC. 
Dolphin is a real hit.

If you like lightweight desktops, I would recommend XFCE or LXDE. I
use XFCE myself, it has all the conveniences of a modern desktop with
none of the intensive stuff. It comes with a very decent collection of
default apps too. :)

Introduction

[Niki Kovacs]

Hi,

I'm an Austrian sysadmin living in Montpezat, a small village in South France. 
I'm 100% GNU/Linux since Slackware 7.1 (around 2001). I've been using 
Slackware and Debian mostly for a few years, then I started working for the 
local town hall and a dozen public libraries around here, to migrate everyone 
from Windows (or nothing) to Linux and free software (nice job, huh?). That 
was back in 2006, and at the time, I chose CentOS for the job, on both servers 
and desktops. 

Last year I created a small computer business, based solely on Linux and free 
software, and aimed at SOHO users: http://www.microlinux.fr. Around the same 
time, I published a book about Linux, focusing on command-line administration, 
but also explaining all the necessary desktop details for "power users" coming 
from the Windows world. The book has been (and still is) quite a success in 
France, with several thousand copies sold. I put a freely available online 
version on my site (check out the "Linux aux petits oignons" link). 

Lately, I got a bit tired of my "good old workhore" CentOS, which feels to me 
like a 4WD Lada, the sort the peasants around here are driving. Nearly 
impossible to destroy, but then, sometimes you feel more like driving a 
Maserati. (Myself I drive an old BMW 1000cc motorbike, but every now and then, 
I enjoy a ride on a buddy's Yamaha R1.) So I went and wiped CentOS 5.5 (GNOME) 
from my main PC and replaced all with a clean Fedora 13 (KDE) install.

So far, I really like it. I'm simply astonished by the look and feel and 
functionality of the KDE desktop (after a false start with KDE4.0 when it came 
out :oD). Looks like in the near future, I'll definitely migrate to Fedora, 
only to keep CentOS on my servers. Looks like a perfect combination. 

I did quite some RTFM (on howtoforge.com and similar sites) on how to fine-tune 
Fedora, and I guess I'll be around here for all the stuff I can't figure out by 
myself.

Cheers from the sunny South of France,

Niki
