再起動後にnvidia-xconfigの編集が保持されない？

NVidia 384.98ドライバーを使用して、Ubuntu 16.04システムにインストールされたGPUのオーバークロックを有効にするbashスクリプトのセットを構築しています。

最初のスクリプトでは、cool-bitsを使用して nvidia-xconfig （リンク先ページの下部）オプションを設定しようとしています。私のスクリプトは以下です

#!/bin/bash

# Secure required privledges
[ "$UID" -eq 0 ] || exec Sudo bash "$0" "$@"

#== Enable overclocking in NVidia X settings (Replace/Add cool-bits for all GPUs installed)
# - 1 (bit 0) - Enables overclocking of older (pre-Fermi) cores on the Clock Frequencies page in nvidia-settings.
# - 2 (bit 1) - Driver will "attempt to initialize SLI when using GPUs with different amounts of video memory".
# - 4 (bit 2) - Enables manual configuration of GPU fan speed on the Thermal Monitor page in nvidia-settings.
# - 8 (bit 3) - Enables overclocking on the PowerMizer page in nvidia-settings. 
# - 16(bit 4) - Enables overvoltage using nvidia-settings CLI options. 
echo "============ CoolBits12_AllCards.sh: Started ============"
echo ">> Setting nvidia-xconfig cool-bits=12..."
Sudo nvidia-xconfig -a --cool-bits=12 --allow-empty-initial-configuration
echo ">> ! Please restart for changes to take effect !"
echo "=========== CoolBits12_AllCards.sh: Completed ==========="

私は基本的にコマンドを実行しています

Sudo nvidia-xconfig -a --cool-bits=12 --allow-empty-initial-configuration

私の最初のetc/X11/xorg.confはそのように見えます

    Identifier "layout"

    Identifier "intel"

EndSection

    Identifier "nvidia"
    Device "nvidia"
    Option "AllowEmptyInitialConfiguration" "on"
    Option "IgnoreDisplayDevices" "CRT"
EndSection

（念のため、スクリプトを数回実行して動作させようとしましたが、これは元の状態ではない可能性があります。これは再起動後のスクリプトを反映しています）

コンピューターを再起動した後、質問の最初にリストされている最初の/etc/X11/xorg.confファイルの内容が適切であることを確認しました。変更されたファイル/ファイルの内容は保持されませんでした。

/etc/X11/xorg.confファイルへの変更が保持されないのはなぜですか？

ある時点で、完了のために、再起動の前に上記のスクリプトを2回実行しました。スクリプトの出力を以下に示します。

============ CoolBits12_AllCards.sh: Started ============
>> Setting nvidia-xconfig cool-bits=12...

NVidiaの画面の破損を修復する同様の問題がありました。 /etc/X11/xorg.confを削除した場合でも、再起動時に再作成されます。解決策は、カスタムの変更を次の場所に配置することです。

/etc/X11/xorg.conf.d/20-nvidia.conf

NVidiaの変更に関する詳細な説明は、 こちら にあります。
