SDDM doesn't show up at boot

Show all headers | View raw

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.
