genaue Problembeschreibung:
Mein Laptop startet nach den booten nicht mehr in die graphische Oberfläche zur Benutzeranmeldung.
Diese Proplem dürfte wohl seit ein paar Wochen bestehen, ohne da ich es bemerkt habe. Denn das oben beschriebene Verhalten trit nur auf, wenn ich keinen! externen Monitor angeschlossen habe.
Der Bootvorgang selbst und die Kernelstartausgaben sind ganz normal auf dem Laptop-Display zu sehen bis zum graphischen Anmeldebild. Hier erscheint nur noch ein Unterstrich in der Konsole 7. Ein Wechsel mit z.B. Strg+Alt+F6 auf Konsole 6 zeigt das typische Konsolen-Eingabebild für Benutzeranmeldung.
Ein Wechsel zurück mit Strg+Alt+F7, also X11-Anmeldebildschirm, zeigt weiterhin nur den Unterschrich oben links.
Sobald ich dann den externen Monitor am DVI-Anschluss des Laptop anschließe und mit Strg+Alt+F6 auf Konsole 6 und zurück mit Strg+Alt+F7 wechsele ist das normale X11-Anmeldebild sichtbar. Danach kann ich den externen Monitor wieder abklemmen und alles bleit ok, bis zum erneuten booten, dann zeigt sich wieder das oben beschiebene Verhalten.
Mit angeschlossenem externen Monitor statet der Laptop ganz normal in das X11-Anmeldebild auf Laptop und exterem Monitor.
Ich habe im Moment keine Ahnung warum lightdm nicht das X11 Anmelde-Bild ohne externen Monitor starten kann.
Im lightdm-log wird zwar “plymouth” angemeckert, da ich jedoch kein KDE benutze brauche ich das nicht, denke ich.
Vieleicht kann jemand helfen.---

Hello,I can't login to my laptop anymore without external monitor in the graphical interface.
exact problem description:
My laptop doesn't start into the graphical user interface after booting.
This problem probably existed a few weeks ago, without me noticing it. Because the behavior described above only occurs if I have no! external monitor connected.
The boot process itself and the kernel startup output are normally visible on the laptop display up to the graphical login screen. Here only an underscore appears in console 7. A change with e.g. Ctrl+Alt+F6 to console 6 shows the typical console input screen for user login.
A change back with Ctrl+Alt+F7, i.e. X11 logon screen, still shows only the signature in the upper left corner.
As soon as I then connect the external monitor to the DVI port of the laptop and switch to console 6 with Ctrl+Alt+F6 and back with Ctrl+Alt+F7, the normal X11 logon screen is visible. Afterwards I can disconnect the external monitor again and everything is ok until rebooting, then the behavior described above shows up again.
With an external monitor connected, the laptop will normally log into the X11 logon screen on the laptop and external monitor.
I have no idea at the moment why lightdm can't start the X11 logon screen without an external monitor.
The lightdm-log reports "plymouth", but since I don't use KDE I don't need it, I think.
Maybe someone can help.
