You can also try to verify sysfs interfaces such as below example
$ ls /sys/class/backlight/
intel_backlight
$ cd /sys/class/backlight/intel_backlight
$ cat max_brightness
12
$echo 12 | sudo tee brightness
$echo 6 | sudo tee brightness
If this does not change brightness, something
Hello,
3 questions here:
1. Can you adjust the screen brightness with the hotkeys?
2. Can you adjust the screen brightness with the slide bar in Settings ->
Power?
3. If not, does it work for you with these 2 methods above on older kernels
(and which version)?
Thanks
