re,
i came a step forward! now i can change the brightness with you console command. But the maximum brightness i can adjust is nit very maximum can i change the maximum an minimum values?
Because when i want to set it for example on 100 The display is in my opinion on 15 oder 20 %.
i have installed the deb packet. But when i try to change the brightness over the terminal, i get an error message
becaue the folder / file nvidia Backlight didnt exsist.
