La luminosità dello schermo del laptop non può essere regolata né con i pulsanti né con il cursore. modificare

11

Ho Ubuntu 17.10 installato su un laptop MSI GT72VR con una singola scheda grafica nVidia GT1060 , grub2 come boot e Unity come desktop. Non posso cambiare la luminosità in alcun modo. Luminoso è sempre al 100% . Ho provato le seguenti opzioni che non hanno funzionato.

COSE CHE NON HANNO FUNZIONATO [USCITE AGGIORNATE AL 30 APRILE 2018]

  • FnI pulsanti + Bright Upo Bright Downmostrano l'icona in linea sullo schermo, ma i brigthnes non possono cambiare.
  • Il dispositivo di scorrimento della luminosità nella barra superiore non funziona.
  • GRUB_CMDLINE_LINUX_DEFAULT = "quiet splashacpi_backlight = vendor"
  • GRUB_CMDLINE_LINUX_DEFAULT = "quiet splashacpi_backlight = native"
  • GRUB_CMDLINE_LINUX_DEFAULT = "quiet splashacpi_backlight = video"
  • GRUB_CMDLINE_LINUX_DEFAULT = "quiet splashacpi_backlight = none"
  • L'utility xbacklight mostra "Nessun output ha proprietà di retroilluminazione"
  • Utilizzo del driver di visualizzazione nouveau X.Org dall'aggiornamento del software
  • Driver binario NVIDIA versione 396
  • Driver binario NVIDIA versione 390
  • La modifica della luminosità dei file su / sys / class / backlight / acpi_video0 / e non funziona
  • Uso dell'ultima versione della mainline upstream del kernel v4.15.7 (28 febbraio)
  • Ubuntu USB live
  • Utilizzo di un file su /etc/X11/xorg.conf con la sezione "Dispositivo" ...
  • Registra la sessione come "Ubuntu su XOrg" e disabilita Wayland

Questo è l'output di journalctl -b | grep -i nvidia (grazie @ WinEunuuchs2Unix)

Ho creato uno script bash temporale per regolare il livello di luminosità . Quindi creo 2 ordinamenti con le impostazioni di mappatura della tastiera per configurare CTRL + Brightness UPo CTRL+ Brightness Downcon questo 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]\n"
        printf "Increase or decrease birghtness on Ubuntu Xorg.\n" 
        printf "WAYLAND MUST BE DISABLED\n\n"

Sembra che Linux possa riconoscere la tua retroilluminazione. Vedi un brightnessfile in /sys/class/backlight/acpi_video0/? In tal caso, prova a scrivere un numero al suo interno e verifica se influisce sulla luminosità dello schermo. Potrebbe essere necessario farlo come root.

Sul mio sistema, i tasti Fn + Brightness non sono nemmeno riconosciuti da Linux in quanto non generano alcun scancodes, ma posso comunque variare la luminosità del mio display dando a tutti gli utenti l'accesso al brightnessfile chmode scrivendo numeri interi in esso .

Ciao @dsstorefile. Sì, ci sono file di luminosità in / sys / class / backlight / acpi_video0 / e posso cambiare il numero (come root) ma non funziona. Luminosità ancora al 100% :( I miei tasti Fn + Brightnes generano scancodes :(

NVIDIA non funziona con Wayland

Come altri hanno scoperto, nVidia non funziona bene con Wayland: Ubuntu 17.10 su Wayland - (Come) posso installare i driver NVIDIA? . La soluzione è passare a Xorg. Per riassumere la risposta da cl-net, attenersi alla seguente procedura:

  • Per installare i driver NVIDIA, eseguire sudo apt install nvidia-384.

  • Inoltre, è possibile forzare la schermata di accesso GDM per utilizzare Xorg per impostazione predefinita.
    Per raggiungere questo obiettivo, basta eseguire sudo nano /etc/gdm3/custom.conf.
    Rimuovi il personaggio #dalla linea # WaylandEnable=false.
    Ora premi Ctrl+ X, quindi Ye Enterper salvare la modifica.

  • Riavvia il sistema operativo Ubuntu, esegui sudo reboot.

Un altro problema che probabilmente incontrerai non è l'audio tramite HDMI al monitor esterno. Per risolvere questo problema, consultare la sezione Domande e risposte: Nessun audio su HDMI su NVIDIA GeForce GTX 1050 Ti

@albertoiNET Wayland era predefinito solo per il 17.10. In 18.04 xorg sarà di nuovo predefinito. Cosa cat /sys/class/backlight/acpi_video0/brightnessrivela? Inoltre è sparito l'errore quando lo fai journalctl -b | grep -i nvidia:?

Non installare 18.04 non appena esce. Stavo solo sottolineando come Wayland sembra più un esperimento e non pronto per la prima serata.
— WinEunuuchs2Unix

@albertoiNET Non installare 18.04 il primo giorno in cui esce. Torna qui e leggi le segnalazioni di bug per alcune settimane per assicurarti di non essere interessato dalla "nuova versione blues".
