Ubuntu 14.04 LTS 64ビットを実行しているSamsung RF711 Intel Core i7ラップトップを持っています。これには2つのグラフィックカードが付属しています。Intelカード（デフォルトで実行されます）とNvidia GeForce GT 540M（私はこれまでUbuntuで作業することができませんでした）です。
マルハナバチでさまざまな構成を試しましたが、optirunを使用しようとすると、最終的にすべてが失敗しました（Xorgログで「ソフトウェアレンダリングキャッシュを割り当てられません」などのエラーが数回見られました）。
今朝、nvidia-primeでもう一度試した。まず、bumblebeeパッケージがインストールされていないことを確認し、実行しました
sudo apt-get purge nvidia*
インストールされているnvidiaパッケージを削除します。私はしました
sudo dpkg-reconfigure lightdm
lightdmがデフォルトであることを確認するために、
sudo apt-get install nvidia-331
331ドライバー、nvidia-prime、nvidia設定などをインストールしました。
再起動後、低グラフィックモードに入ります。ここから、デスクトップに戻ることができた唯一の方法は、nvidiaパッケージを削除することです
sudo apt-get purge nvidia*
そして再起動します。もちろん、これはラップトップを最初の状態に復元します。
lspciの出力は次のとおりです。grep 3D

あなたのためのもう少し情報：1）私はちょうど今同じ結果でnvidia-337ドライバーを試しました。2）切り替え可能なグラフィックスに悩まされず、いつもNvidiaカードを使用したい（BIOSでこれを試しましたが、選択するオプションがありませんでした）。もちろん、理想的な切り替え可能なグラフィックスを可能にするソリューションがあれば！

BIOSで、最初に有効にするビデオカードを選択するオプションはありますか？これは品質の高いメーカーの間ではかなり一般的であり、GeForce GT 540Mをオンボードインテルより先に最初にアクティブ化すると、排他的に選択できないため、役立つ場合があります。

こんにちは、返信ありがとうございます。BIOSを調べたところ、グラフィックカードを選択するためのオプションがまったく見つかりませんでした。そうは言っても、私はBIOSの使用について特に知識が豊富ではないので、誰かが私のシステムに固有の提案があれば、それも役に立ちます！

システムのメーカーとモデルは何ですか？

現在、Nvidiaカードはまったく使用できません。使用できるようにしたいと考えています。実行するプログラムごとに使用するカードを選択できるのが理想的ですが（Bumblebeeでできるように）、Nvidiaカードを使用できる限り、デフォルトですべてのカードが使用されているとしても満足です。
