Hallo @tomfa-ng, leider bin ich noch nicht weitergekommen.
Ich habe die oben genannten Dateien mit meinem Zweitgerät (mit Leap 15.1) überprüft, und wie du sagst: es sieht dort genauso aus. Allerdings funktioniert dort das graphische Einloggen problemlos.
Hier jetzt die neuen Angaben:
Code
tux:/home/felix # cat /etc/sysconfig/displaymanager
## Path: Desktop/Display manager
## Description: settings to generate a proper displaymanager config
## Type: yesno
## Default: no
#
# Allow remote access (XDMCP) to your display manager (xdm/kdm/gdm). Please note
# that a modified kdm or xdm configuration, e.g. by KDE control center
# will not be changed. For gdm, values will be updated after change.
# XDMCP service should run only on trusted networks and you have to disable
# firewall for interfaces, where you want to provide this service.
#
DISPLAYMANAGER_REMOTE_ACCESS="no"
## Type: yesno
## Default: no
#
# Allow remote access of the user root to your display manager. Note
# that root can never login if DISPLAYMANAGER_SHUTDOWN is "auto" and
# System/Security/Permissions/PERMISSION_SECURITY is "paranoid"
#
DISPLAYMANAGER_ROOT_LOGIN_REMOTE="no"
## Type: yesno
## Default: yes
#
# Let the displaymanager start a local Xserver.
# Set to "no" for remote-access only.
# Set to "no" on architectures without any Xserver (e.g. s390/s390x).
#
DISPLAYMANAGER_STARTS_XSERVER="yes"
## Type: yesno
## Default: no
#
# TCP port 6000 of Xserver. When set to "no" (default) Xserver is
# started with "-nolisten tcp". Only set this to "yes" if you really
# need to. Remote X service should run only on trusted networks and
# you have to disable firewall for interfaces, where you want to
# provide this service. Use ssh X11 port forwarding whenever possible.
#
DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN="no"
## Type: string
## Default:
#
# Define the user whom should get logged in without request. If string
# is empty, display standard login dialog.
#
DISPLAYMANAGER_AUTOLOGIN=""
## Type: yesno
## Default: no
#
# Allow all users to login without password, but ask for the user, if
# DISPLAYMANAGER_AUTOLOGIN is empty.
#
DISPLAYMANAGER_PASSWORD_LESS_LOGIN="no"
## Type: yesno
## Default: no
#
# Display a combobox for Active Directory domains.
#
DISPLAYMANAGER_AD_INTEGRATION="no"
## Path: Desktop/Display manager
## Type: string(Xorg)
## Default: "Xorg"
#
DISPLAYMANAGER_XSERVER="Xorg"sowie
Code
tux:/home/felix # journalctl --system | grep -Ei -B5 -A15"dracut|error"
grep: 15dracut|error: ungültiges Argument für die Kontextlänge(Nächster Quellcode kommt extra)
Ich hoffe, du kannst das interpretieren?
Besten Dank schonmal, für deine/eure Mühen!
