Mageia forum

Hello,

I installed mageia 2 on my macbook 4,2. I had some little problems, but nothing seriously.

The keyboard brightness control doesn't works.

The kernelmodule apple_bl is loaded:

Code: Select all

lsmod | grep -i apple_bl
apple_bl               13225  0


There is missing the link
/sys/class/backlight/apple_backlight which is described here:
https://bugs.mageia.org/show_bug.cgi?id=5570

I only have acpi_video@ and intel_backlight@.
The intel_backlight is for the display.

Anybody with a hint?

Thanks for reading my post.

I tested gnome insted of kde and the keyboard light works. But its a bit confusing why there is missing the link. I located the system directory of the backlight:
/sys/devices/platform/applesmc.768/leds/smc\:\:kbd_backlight/

I tried to create the link apple_backlight in the directory /sys/class/backlight. Doesn't works.

I can change the light in gnome with keys F5 and F6. In kde I have to open a terminal and become root.

Code: Select all

 
su
cp /sys/devices/platform/applesmc.768/leds/smc::kbd_backlight/


Light off:

Code: Select all

 
echo 0 > brightness


Light full power:

Code: Select all

 
echo 255 > brightness
