Habe gerade eine Server-Box von einem aktuellen Debian 9 auf Folgendes aktualisiert:
# uname -a
# Linux server 4.19.0-6-amd64 #1 SMP Debian 4.19.67-2+deb10u2 (2019-11-11) x86_64 GNU/Linux
Jetzt zeigt das Grafikterminal nach dem Grub-Menü nur noch einen blinkenden Cursor an. Ich kann mich mit tty1 anmelden und auch per RDP auf die Box zugreifen und einen vollständigen Desktop (LXDE) starten.
Das boot.log sieht in Ordnung aus, aber in dmesg gibt es zwei große Lücken, die mir aufgefallen sind, die ich aber nicht verstehe:

Irgendeine Idee, wo ich als nächstes nachsehen könnte, um das Problem zu finden?

Danke für den Tipp, Piotr! Das hat mir weitere Ideen gegeben. Für LXDE muss ich nach lighthdm suchen:journalctl -u lightdm -e

Das /var/log/lightdm/lightdm.loglässt mich auf ein Xserver-Problem hinweisen in/var/log/lightdm/x-0.log

Ich habe die Bus-ID wie folgt gefunden lspci:
00:02.0 VGA compatible controller: Intel Corporation Device 3e98
Dann habe ich Folgendes erstellt, /etc/X11/xorg.confum die Bus-ID anzugeben. Jetzt funktioniert alles.
Section "Device"
Identifier "dev0"
BusID "pci0:0:2:0:"
EndSection
Ich lasse die akzeptierte Antwort offen, falls jemand weiß, warum die Bus-ID vom System nicht erkannt wurde. Bei Bedarf gebe ich gerne weitere Hinweise.
