Bumblebeeを使用してデュアルモニタを設定する際に問題があります。 Bumblebeeおよびnvidiaドライバが正常にインストールされた可能性があります。実行され、glxgears完全にoptirun glxgears異なるfpsを提供し、nvidia-settings正常に見えます。また、外部モニタをhdmiに接続して実行した後：
export DISPLAY=:8
optirun true
sleep 5
optirun glxgears
glxgearsが外部モニタに表示されるので、これまではすべてがうまくいくようです。
しかし、ディスプレイミラーリングのようにxrandrを動作させる方法がわかりません。私が正しく理解したら、Bumblebeeを使用すると、2番目のXサーバーが起動するため、2台の:8Xサーバーが稼働しています（デフォルトの内蔵モニターがオンになっていて、:0HDMIを使用する2台目のモニターがオンになっていますが、:8)これは問題ですか？別のXサーバーにミラーリングされた画面がある可能性はありますか？
私はたくさんのチュートリアルを試しましたが、ほとんどすべてのチュートリアルで使用する出力が異なりますxrandr（おそらくHDMIがnvidiaチップに接続されていないためですか？）。私の結果は次のとおりです
$ export DISPLAY=:0
$ xrandr -q
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
XWAYLAND0 connected 1920x1080+0+0 340mm x 190mm
1920x1080 59.96*+
$ export DISPLAY=:8
$ xrandr -q
Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 16384 x 16384
HDMI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 640mm x 360mm
1920x1080 60.00*+ 59.94 50.00 29.97 25.00 24.00 23.97 60.00 50.04
1360x768 59.80
1280x1024 60.02
1280x720 59.94 50.00
1024x768 60.00
他の人にはHDMI録音機能があり、:0出力先を使って実行できますxrandr。しかし、例えば実行すると
$ export DISPLAY=:0
$ xrandr --output XWAYLAND0 --primary
$ xrandr --auto --output HDMI-0 --mode 1920x1080 --right-of XWAYLAND0
予想されるエラーが発生します。warning: output HDMI-0 not found; ignoring
したがって、主な質問は、XとBumblebeeがミラーリングディスプレイを持つように設定する方法です。
