X -configureが機能しない、[作成された画面の数が検出されたデバイスの数と一致しない]
デスクトップ環境としてKDEでdebianをインストールしましたが、nvidia-driverをアンインストールした後に次の状況が発生しました。 xorg.confファイルがないため、Sudo X -configure Intelドライバー用のファイルを再生成します。しかし、私は次のエラーを受け取ります：

Debian 9.xのnouveau X11ドライバーのバージョンが古すぎて、NVidia dGPUモデルをサポートできません。ハードウェア構成で許可されている場合（つまり、iGPUが必要なディスプレイ/コネクタに物理的に接続されている場合、マルチGPU Optimusラップトップでは常に正しいとは限らない場合）、Intel iGPUのみを使用して続行できる場合があります。
ほとんどの場合、最新バージョンのXorgでは、完全なxorg.confファイルは不要です。 /etc/X11/xorg.conf.d/intel-only.confのようなミニ設定ファイルを書くことでうまくいくかもしれません：
Section "ServerLayout"
Identifier "Layout0"
Option "AutoAddGPU" "false"
Screen 0 "IntelScreen"
EndSection
Section "Device"
Identifier "IntelDevice"
BusID "PCI:0:2:0"
Driver "intel" # or maybe "modesetting"?
EndSection
Section "Screen"
Identifier "IntelScreen"
Device "IntelDevice"
EndSection
これにより、XサーバーはIntel iGPUのみを使用し、現時点ではNvidia dGPUを無視し、すべての入力デバイス、ディスプレイ解像度などを自動検出するように制限されます。
