Hi all!
I use Lenevo S10-2.
I run the following command as root to change brightness level of LCD:
$ echo 3 > /sys/class/backlight/acpi_video0/brightness
now the brightness level has been changed to 3.
But I see that the actual brightness of LCD isn't changed.
I got the same result when I control brightness via procfs (/proc/acpi/video/...).
Does Lenovo S10-2 use another way to control LCD brightness ? (Except using Fn function key)
