デバッグディスプレイマネージャが起動しませんでした。

デバッグディスプレイマネージャが起動しませんでした。

私はMacbookPro10,1(レティーナ)の誇り高い所有者です。私はそれにDebian stableをインストールし、今まで今日までうまくいきます。

grubをそのままにしてデフォルトモードで起動すると、表示テキストが表示されますが、ログイン画面は表示されません。最後の数行:

...
Started WPA Supplicant
Started User Manager for UID 103

リカバリモードで再起動し、ネットワーク管理者を起動でき、問題はありません。場合に備えて、nvidiaパッケージを再インストールしました(apt-get install -tstretch-backports nvidia-driver)。

だから私の目標は、gdm3が起動しない理由を診断することです。マイコンピュータでは、++キーまたは++キーがキーボードにないCtrlため使用できません。AltBackspaceAlt grPrint ScreenK

仮想ttyは使用できません(Ctrl+はF1プロンプトを表示しません)。

だから今ssh + PermitRootLoginをyesに設定しました。

リモートSSHで次のコマンドを試しても何も起こりません。

# service gdm3 restart

しかし、(私のリモートSSHでも)起動でき、startxリモートMacbookProでXセッションが正しく表示されることがわかります。

gdm3が起動していないことを確認する手順は何ですか?

ちなみに、私の以前の習慣はgrep /var/log/debugでしたが、今回は何も起こりませんでした。

# grep gdm3 /var/log/debug
