私の仮想マシンはDebian OS上で動作していて、突然ウィンドウが点滅し続けるまで正常に実行されました。電源を切ってから戻ってログインすると、グラフィカルインターフェイスが消えました。これでログイン画面は次のようになります。
情報：
debian : debian-10.7.0-amd64-xfce-CD-1.iso for Debian ISO image
host : Win 10
virtualbox : VirtualBox 6.1.16
何が起こっていて、どのように解決するのか知っていますか？
PS：アイドルモードに入るとこれが起こるようです。システムをインストールして初めてログインしましたが、すべてがうまくいきました。それからしばらく手を触れないとアイドルモードに入り衝突が発生しました。
PS2：GUIレスモードでログインしてコマンドを使用すると、グラフィックstartxインターフェイスに入りますが、マウスが動くことができる以外は何も起こりません。
PS3：また、起動時にいくつかのエラーが発生することがわかりました。sensor not found error
PS3：dmesgで再インストールエラーが見つかりましたが、関連があるかどうかはわかりません。

アップデート：問題があるようですdebian-10.7.0-amd64-xfce-CD-1。これがDebianコミュニティに知られているバグかどうかはわかりませんが、に変更した後はdebian-10.5.0-amd64-xfce-CD-1これまでうまく機能しているようです。
