Wie äußert sich der Fehler?
Entweder wird beim Herunterfahren das Ubuntu-Logo mit den (endlos) blinkenden Punkten angezeigt, der Rechner stellt sich aber nicht innerhalb von 3 Minuten aus.
2. Oder es wird ein dunkler Bildschirm angezeigt, der Rechner stellt sich aber nicht innerhalb von 3 Minuten aus.
3. In einem Fall wurde auf dunklem Bildschirm folgender Text angezeit:
[3182.279731] nouveau 0000:01:00.0 DRM: GPU lockup-switsching to software fbcon
INFO: task systemd-shuutdow:1 blocked for more than 120 seconds
Tainde: G OE 5.0.0-25generic #25~18.04.1-ubuntu
4. Wenn ich den PC im gesicherten Modus starte und dann wieder runterfahre, bekomme ich die folgenden letzen drei Zeilen
[ OK ] Reched target Unmout All Filesystems.
[ OK ] Reched target Final Step.
Starting Power-Off...
Dann hängt sich der Rechner wieder auf.
Wann trat der Fehler erstmals auf?
Der Fehler trat m.E. mit dem Wechsel auf den Kernel 5.x unter Ubuntu 18.04.3 LTS auf.
Was habe ich bisher versucht?
Bisher habe ich die folgenden drei Tipps, die unter https://wiki.ubuntuusers.de/Herunterfahren/ beschrieben sind, ausprobiert: (1) ACPI erzwingen, (2) Power-Off über APM und (3) "HDA"(High Definition Audio) abschalten. Das hat aber keinen Erfolg gebracht.
