自分で試したこと

ログインのパスワードが間違っている可能性があるとのことで、

以下、3つのファイルを確認しましたが、中身を理解することができませんでした。

そもそも 設定 で リモートデスクトップ を有効にしているのでしょうか?
(リモートログイン、リモートコントロールのどれ?)

Ubuntu のバージョン(ディストリビューション)も明記してください。

  1. ubuntuのバージョンは、「Ubuntu 22.04.5 LTS」になります。
    リモートデスクトップの有効は、以下で有効だと考えています。

    # gsettings get org.gnome.desktop.remote-desktop.rdp enable
    true
    

わからないけど、とりあえずざっと見てディスプレイ番号が合っていないのが気になりました。
