私は現在、ラップトップで GTX 780m GPU を搭載した Ubuntu 14.04 を実行しており、Bumblebee で nvidia-331 ドライバーを使用しています。
画面の明るさをコントロールできなかったのですが、インターネットのヒントを参考にして、ファイルに次の行を追加しました。/usr/share/X11/xorg.conf.d/20-intel.conf:
Section "Device"
Identifier "card0"
Driver "intel"
Option "Backlight" "intel_backlight"
BusID "PCI:0:2:0"
EndSection
その後、明るさをうまくコントロールできるようになりました。問題は、その後、bumblebee が動作しなくなり、たとえば、primusrun を使用して Steam を開こうとすると、次のメッセージが表示されることです。
Running Steam on ubuntu 14.04 64-bit

optirun steam を試すと、次のように表示されます:
[ 6051.673074] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) Server terminated successfully (0). Closing log file.
[ 6051.673179] [ERROR]Aborting because fallback start is disabled.
インターネットで調べてみると、次のコードを追加すると、次のようになると指摘する人がいました。
Section "Screen"
Identifier "Default Screen"
Device "DiscreteNvidia"
EndSection
ファイルの先頭へ/etc/bumblebee/xorg.conf.nvidia動作するはずだったが、動作しなかった。この変更を適用した後、試してみるとプリムスラン スチーム、私はこう思います:

それで、明るさコントロールとバンブルビーの両方を動作させる方法について何かアイデアはありますか?
よろしくお願いします！
