| |
Hi,
Since 2.6.39 I have a /sys/class/backlight/apple_backlight/ interface and I can change the brightness by echoing values to the relevant brightness file.
That's great but there's a little problem:
On the 256 levels of brightness that my screen supports, I can only reach 16 of the 128 upper values. It means that the lowest brightness I can access on Linux is at 50% of the real maximum brightness.
Thanks, -- Bastien
