Son zamanlarda Ubuntu arkadaşı 18.04'ü XPS 15 9560'ım üzerine kurdum. Ekran parlaklığını hiçbir şekilde ayarlayamıyorum. Aşağıdakileri denedim:
- Acpi_backlight = vendor'u önyükleme parametrelerinde ayarlayın
- Aşağıdaki sonuçları veren xbacklight kullanıldı
.
xypnox@xypnox-xps:~$ xbacklight -set 50
No outputs have backlight property
Ayrıca ben başka bir soru takip xbacklight: Hayır çıkışları arka ışık özelliği vardır - Hayır / sys / class / arka ışık klasör ve için çıkış sudo find /sys/ -type f -iname '*brightness*'
DİR
xypnox@xypnox-xps:~$ sudo find /sys/ -type f -iname '*brightness*'
