- by YumYumYum
I am controlling my PC with SSH and scripting. How can i change the brightness, color and sharpness from command line?
Try 1: failed
$ sudo redshift -t 5000:5000 -g .5
Cannot list GNOME panel applets.
Initialization of gnome-clock failed.
Trying next provider...
Latitude and longitude must be set.
Try 2: failed
$ cat brightness
20
$ cat max_brightness
20
$ echo 1 | sudo tee /sys/class/backlight/acpi_video0/brightness
1
$ echo 20 | sudo tee /sys/class/backlight/acpi_video0/brightness
Any alternative way to do?
