#241428 — SDDM doesn't show up at boot

Hi.

I was trying to set up the keyboard for the whole system
with "localectl set-x11-keymap pc105 us altgr-intl".  Before
that, it did not have the altgr-intl variant.

I have LXQt installed, with SDDM as the display manager.
After booting the PC again, SDDM was no longer showing up
when the PC finished starting.  Through some research
reading the systemd journal, I found that "sddm-greeter"
could not connect to the X server.

I also found that, if I login at a virtual console as root and run:
"systemctl isolate multi-user.target" and then
"systemctl isolate graphical.target"
to try to reload the graphical system, then everything works fine
and SDDM shows up as normal.  It also allows me to use
the keyboard with the chosen configuration.

Later, I removed the "altgr-intl" option from "/etc/default/keyboard"
and rebooted, and voilá... everything was back to normal and
SDDM showed up at the end of the boot process.

I tried rebooting many times, changing some localization settings,
and the problem appeared exactly only when the "altgr-intl"
was enabled in "/etc/default/keyboard".  The keyboard works
well when you set it up through LXQt.

Now, while writing this message, I tried it again and now
the kernel reports a segmentation fault in "sddm-greeter"
after it reads "/usr/share/xsessions/lxqt.desktop".  Of course,
everything fails again leaving me with only the mouse cursor
and a black screen.

Before I go to report this as a bug, I wanted to know
if I am not the only one with this problem.

Please, ¿could someone with LXQt and a little free time
tell me whether the system fails to start when adding
XKBVARIANT="altgr-intl" to "/etc/default/keyboard"
and then rebooting?  You can go back to normal behaviour
just logging in at a virtual console, removing the "altgr-intl"
part from "/etc/default/keyboard" and rebooting.

Thanks in advance.

Hi,

First things first: bring your machine up to date - there is now 10.11.
[Or update to Debian 11 - but read release notes :) ]

I think you may have two independent problems here: changing keyboard
layout shouldn't cause problems with the X server.

All best, as ever, 

Andy Cater

Ok, I'm working on it.

I do not think that the problem is with the X server itself, but with SDDM.
See what I wrote here:

The problem is with the "sddm-greeter".  SDDM itself
(I mean, "/usr/bin/sddm") is still running when this happens,
and I can see and move the cursor around.

On account of having run Debian a long time, I set up my keyboard
using   dpkg-reconfigure keyboard-configuration, so I have no
experience of running localectl. However, the man page says:

 set-x11-keymap LAYOUT [MODEL [VARIANT [OPTIONS]]]
     Set the system default keyboard mapping for X11 and the virtual
     console. This takes a keyboard mapping name (such as "de" or
     "us"), and possibly a model, variant, and options, see kbd(4) for
     details. Unless --no-convert is passed, the selected setting is
     also applied as the system console keyboard mapping, after
     converting it to the closest matching console keyboard mapping.

So might it be worth trying:

  localectl set-x11-keymap us pc105 altgr-intl

Could you post the contents of /etc/default/keyboard after
running each of the commands above. (It seems pointless for me to try
to see the effects, as I don't use a DE, DM or "greeter".)

Cheers,
David.

Ups, I made a mistake writing the email, sorry.  I did write the command
right.  Thanks for the correction.

Before the command:
## KEYBOARD CONFIGURATION FILE
#
## Consult the keyboard(5) manual page.
#
#XKBMODEL="pc105"
#XKBLAYOUT="us"
#XKBVARIANT=""
#XKBOPTIONS=""
#
#BACKSPACE="guess"
#
(without the first column of #)

After the command:
#XKBMODEL=pc105
#XKBLAYOUT=us
#XKBVARIANT=altgr-intl
#BACKSPACE=guess
#
(without the #)

Thanks for your reply.  Have a nice day.

#241540 — [SOLVED] SDDM doesn't show up at boot

Hello,

Thank you very much Mr. Cater and Mr. Wright.

Just after updating Debian to 10.11, the problem was solved.
Now I can set up the keyboard system-wide correctly,
and SDDM is starting as expected.  Thanks again,
Mr. Cater.

Also,

I tried "dpkg-reconfigure keyboard-configuration" and I have to admit
it was much easier to use.  It has very well explained steps with full
keyboard configuration and a straightforward selection process
among the options.

Unfortunately, it did not work on the virtual terminal, only on the
X Window System.  "localectl" also sets some configuration
in "/etc/vconsole.conf" but it does not work either.  However,
one of the last steps in the keyboard-configuration
of dpkg-reconfigure suggested that I could use the keys combination
Ctrl + . (period) as a compose key (no matter whether I chose
another key as a compose key); thanks to that, I can now write
accented letters in the console.  Thanks again, Mr. Wright.

Have a good day.

I have some bad news, it is happening again.  Now, the problem is not
the keyboard; instead, if I change from virtual terminal (VT) 7 to 1 pressing
Ctrl + Alt + F1 before SDDM finishes loading, then when I come back
to VT 7 it gets stuck again.

I saw the logs with "journalctl -xe" and the messages are the same,
"sddm-helper" can not connect to display :0 of the X server,
or any display and it returns with an error.  The "systemd" session
for "sddm" is stopped and the VT 7 only has a black screen and a cursor;
SDDM itself and the X server is still running.

What do you think?  Should I report this as a bug?

Well, thanks for your time and help.

Have a nice day.

Good to hear, but sorry it didn't stick. Your next post looks all
to do with DEs and greeters, so out of my experience.

That may depend on whether you ran it on a "real" VC (rather an
oxymoron) or on an Alt-Ctrl-Fn console reached from X. I've
certainly had aspects not work when run in the latter manner,
particularly /etc/console-setup/remap.inc stuff IIRC.

I've never seen that file, and running localectl didn't create it
either. This part of systemd is as yet unexplored by me. I can only
keep up with a certain amount of change at one time.

Well, that came as a surprise to me.

Excuse me, Mr. Wright, what do you mean by a "real" virtual console?
Those ones you reach by pressing Ctrl+Alt+Fn are virtual consoles,
right?

Well, it is a little confusing.

Have a good day.

Seven virtual terminals - full screen grey/white on black - if you don't 
install X/Wayland/any desktop environment - Alt-F1 to Alt-F7.

If you're running from within X, there's an extra layer / ke4ystrokes to
trap is what's meant, I think.
