サーバー ボックスを最新の Debian 9 から次のものにアップグレードしました:
# uname -a
# Linux server 4.19.0-6-amd64 #1 SMP Debian 4.19.67-2+deb10u2 (2019-11-11) x86_64 GNU/Linux
現在、グラフィック ターミナルには、Grub メニューの後に点滅するカーソルのみが表示されます。tty1 を使用してログインできます。また、ボックスに RDP で接続して、完全なデスクトップ (LXDE) を起動することもできます。
boot.log は問題ないように見えますが、dmesg には 2 つの長い時間ギャップがあり、それが目を引きましたが、理解できません。

問題を見つけるために次にどこをチェックすればよいかご存知ですか?

ヒントをありがとう、Piotr! おかげでもっとアイデアが浮かびました。LXDE の場合は lighdm を確認する必要があります:journalctl -u lightdm -e

私は以下を使用してバスIDを見つけましたlspci:
00:02.0 VGA compatible controller: Intel Corporation Device 3e98
/etc/X11/xorg.conf次に、 busID を指定するために以下を作成しました。これで、すべてが機能しています。
Section "Device"
Identifier "dev0"
BusID "pci0:0:2:0:"
EndSection
busID がシステムによって認識されなかった理由を誰かが知っている場合に備えて、承認された回答をオープンのままにしておきます。必要に応じて、さらに情報を提供させていただきます。
