La luminosité de l'écran de l'ordinateur portable ne peut pas être ajustée avec les boutons ou le curseur. modifier

Question

J'ai Ubuntu 17.10 installé sur un MSI GT72VR ordinateur portable équipé d'un seul nVidia GT1060 carte graphique, grub2 en tant que boot et Unity en tant que bureau. Je ne peux en aucun cas changer la luminosité. Bright vaut toujours 100% . J'ai essayé les options suivantes qui n'ont pas fonctionné.

CHOSES QUI N'ONT PAS FONCTIONNÉ [SORTIES MISES À JOUR AT 30 AVRIL 2018]

Fn + Bright Up ou Bright Down Les boutons indiquent l'icône à l'écran, mais les brigades ne peuvent pas changer.
Le curseur de luminosité à la barre supérieure ne fonctionne pas.
GRUB_CMDLINE_LINUX_DEFAULT = "quiet splashacpi_backlight = fournisseur"
GRUB_CMDLINE_LINUX_DEFAULT = "calme splashacpi_backlight = natif"
GRUB_CMDLINE_LINUX_DEFAULT = "calme splashacpi_backlight = vidéo"
GRUB_CMDLINE_LINUX_DEFAULT = "calme splashacpi_backlight = aucun"
L'utilitaire xbacklight indique "Aucune sortie n'a de propriété de rétro-éclairage"

J'ai créé un script temporellement bash pour ajuster le niveau de luminosité . Ensuite, je crée 2 tranchants au niveau des paramètres de mappage du clavier pour configurer CTRL + Brightness UP ou CTRL + Brightness Down avec ce script:

#!/bin/bash # Step brightness value STEP=2 # Max brightness value (defult 100) MAX=100 # Min brightness value (defult 0) MIN=0 COMMAND=$(xrandr --verbose | grep -i brightness | cut -f2 -d':' | tr -d "[:space:]") ACTUAL=$(bc -l <<< $COMMAND*100 | cut -f1 -d'.') while getopts ": u d" input do case $input in u) if [ $ACTUAL -lt $MAX ];then TOTAL=$(bc -l <<< $(($ACTUAL+$STEP))/100) $(xrandr --output DP-0 --brightness $TOTAL) fi;; d) if [ $ACTUAL -gt $MIN ];then TOTAL=$(bc -l <<< $(($ACTUAL-$STEP))/100) $(xrandr --output DP-0 --brightness $TOTAL) fi;; ?) printf "Usage: brightness [OPTION]
" printf "Increase or decrease birghtness on Ubuntu Xorg.
" printf "WAYLAND MUST BE DISABLED

" printf " -u	 Increases brightness
" printf " -d	 Decreases brightness
" exit 2;; esac done

Et dans l'ensemble raccourci personnalisé, j'ai ajouté ceci

NVIDIA ne fonctionne pas avec Wayland

Comme d'autres l'ont découvert, nVidia ne fonctionne pas bien avec Wayland: buntu 17.10 sur Wayland - (Comment) puis-je installer les pilotes NVIDIA? . La solution consiste à passer à Xorg. Pour résumer la réponse de cl-net , procédez comme suit:

Pour installer les pilotes NVIDIA, exécutez Sudo apt install nvidia-384.
De plus, vous pouvez forcer l'écran de connexion GDM à utiliser Xorg par défaut.
Pour cela, exécutez simplement Sudo nano /etc/gdm3/custom.conf.
Supprimez le caractère # de la ligne # WaylandEnable=false.
Maintenant, appuyez sur Ctrl+X, puis Y et Enter pour sauver ce changement.
Redémarrez le système d'exploitation Ubuntu, exécutez Sudo reboot.

Un autre problème que vous rencontrerez probablement est l'absence de son via HDMI vers un moniteur externe. Pour résoudre ce problème, consultez ce Q & A: Pas d’audio sur HDMI sur le NVIDIA GeForce GTX 1050 Ti

Il semble que Linux puisse reconnaître votre rétroéclairage. Voyez-vous un fichier brightness dans /sys/class/backlight/acpi_video0/? Si vous le faites, essayez d’y inscrire un chiffre et voyez s’il affecte la luminosité de votre écran. Vous devrez peut-être le faire en tant que root.

Sur mon système, les touches Fn + Brightness ne sont même pas reconnues par Linux car elles ne génèrent aucun scancode, mais je peux toujours faire varier la luminosité de mon affichage en donnant à tous les utilisateurs l'accès au fichier brightness avec chmod et en écrivant des entiers. dans ça.
