Hello Didier,
I think the installer was using an older version of BRLTTY and an older kernel
version as well. If my memory serves me correctly the kernel in the installer
was 6.1-something or other. I think there is an issue with permissions with
BRLTTY in 6.2 and it's not TIOCSTI because if I run the command: sysctl -a I
get this output telling me it is enabled: sysctl dev.tty.legacy_tiocsti=1
I have the same issue on Ubuntu, and Debian as well, so it's not a Slint issue.
Even if I log in as superuser (root) I don't get any input. The output to
brltty whether on Debian, Ubuntu, or Slint is the same. I've posted it as you
requested it but I don't think we can do anything as the issue is upstream:

I've joined the groups as a regular user but that hasn't changed anything.
Not to worry. I will just wait for it to get fixed at some point (when they
realise there is a problem). Hopefully, in days or weeks rather than months or
years.
Other than that, I'm enjoying Slint and the packages that are already installed.

Subject: [slint] Re: Braille Input
Hello Paul,
Caveat: I do not own a braille device and do not know how to use one.
@All: if you use input from your braille device (instead or in addition to a
regular keyboard), feel fee to answer feel free to complete of fix what I write
in this post.
1. I am puzzled that you had braille input during installation but not after.
If the most recent brltty version was installed from a remote repository
(should be the case if you had an internet connection during installation) or
you updated the system after installation you have brltty 6.6 whereas the
installer has 6.5. I do not know if that matters but anyway to be sure please
post the output of "brltty --version"
2. In /etc/brltty.conf there is chapter Keyboard Settings. If not done please
check the default settings and edit them as need be (and also other settings,
of course), then restart brltty as indicated below.
3. The way to start the daemon during the startup sequence is to make the file
/etc/rc.d/rc.brltty executable, using sudo or as root: chmod 755
/etc/rc.d/rc.brltty. Then you can type /etc/rc.d/rc.brltty start|stop|restart
(we do not uses systemd services in Slint).
4. As indicated in https://slint.fr/en/HandBook.html#_use_slint_with_braille ;
you (the regular user) should be a member of the braille group. For that, as
root or using sudo please type: usermod -G braille -a username paul (I assume
that you username is "paul").
4. In Slint by default brltty is started as root. If you started brltty as
regular user, try to kill it then start it as root. Does the issue remain?
I mention this because granting capabilities is not necessary if brltty is
started as root.
5. Does the "no braille input" occurs in thr console or only in a graphical
environment like Mate?

Hello all,>===============================================================================
@Didier
I have braille input when installing Slint on an old Intel NUC to test
it out but after launch I don't have braille input. BUT I do have the
command brltty-setcaps which I don't have on Ubuntu. Do you know how
to enable the braille keyboard input on Slint?
The same capabilities aren't granted: sys_admin, cap_sys_tty_config,
and cap_mknod
Paul
