今のところ、私はnouveau / intelにこだわっています。何が起こっているのでしょうか？/etc/X11/xorg.confファイルが見つからないことが問題の可能性がありますが、なぜ存在しないのかはわかりません。
注：16.04の主要リリースでは、エラーから変更されていないデバイス検出と全く画面が見つからないと（互換NVIDIA Xドライバが見つかりません）GLX拡張の初期化に失敗しました。さて、lightdmは簡単に起動しますが、ログイン画面を通過することはできません。
さらに編集：セキュアブートを常に無効にしました。nvidiaドライバーを追加したbumblebeeをインストールしました（304と340を試しました）が、nVidiaビデオカードを使用してプログラムを起動できませんでした。さらなる調査により、nvidiaのmodprobeは次のような理由で失敗していることが示されています。
could not insert 'nvidia': Unknown symbol in module, or unknown parameter (see dmesg)
新しいバージョンのドライバー（361）を試しましたが、失敗し続けました。i915ドライバーがこの問題を引き起こしていることをどこかで読んだことがありますが、インストールしていません。
詳細：これが根本的な原因のようです。nVidiaドライバーとそのDKMSモジュールがインストールされているため、カーネルに挿入できませんでした（modprobeを使用）。報告されたエラーは、特定のPCIポート（lspciによると、あるべきポート）が見つからないというものでした。正確な言葉遣いは保存していませんが、ごめんなさい。

nvidiaグラフィックドライバーppaからnvidia-364をインストールするまで、私は同じ問題を抱えていました。ただし、prime-indicatorをインストールしたときにログインのバグが再発したため、再度削除する必要がありました。しかし、nvidia-364と無効化されたセキュアブートは動作します。Nvidia 940Mカードを持っています。

できます！nvidia-364をインストールして再起動すると、問題が修正されました。Unityにアクセスするには、〜/ .config / dconf / userを削除する必要がありました。

私は同様の問題を抱えている-私は思う。Xに実際に使用しているディスプレイアダプターを質問に追加できますか？Intelですか、それともNVIDIAですか？
