Les modifications apportées à nvidia-xconfig ne prennent pas effet après le redémarrage?

Je construis un ensemble de scripts bash pour activer l'overclocking des GPU installés sur mon système Ubuntu 16.04 à l'aide du pilote NVidia 384.98.

Pour mon premier script, j'essaie de définir l'option cool-bits (bas de la page liée) via nvidia-xconfig. Mon script est ci-dessous

#!/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 ==========="

Je ne fais que lancer la commande

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

Mon etc/X11/xorg.conf initial ressemble à cela

(Même si cela n’est pas le cas, j’ai exécuté le script plusieurs fois pour essayer de le faire fonctionner, il se peut que ce ne soit pas ce qu’il était à l’origine. Cela reflète le script après un redémarrage)

J'ai vérifié qu'après le redémarrage de l'ordinateur, le premier contenu du fichier /etc/X11/xorg.conf indiqué en premier dans la question était en place; le fichier altéré/le contenu du fichier ne contenait pas.

Pourquoi mes modifications dans le fichier /etc/X11/xorg.conf ne sont-elles pas conservées?

À un moment donné, j'ai exécuté le script ci-dessus deux fois avant un redémarrage, par souci d'efficacité, et potentiellement plus d'informations. La sortie du script est affichée ci-dessous.

============ CoolBits12_AllCards.sh: Started ============

J'ai eu un problème similaire lors de la réparation de l'écran déchirant pour nVidia. Même si je supprimais /etc/X11/xorg.conf, il serait recréé au redémarrage. La solution consiste à intégrer vos modifications personnalisées dans:

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

Une description détaillée des modifications de nVidia peut être trouvée ici .
