Sorry for my english...
I installed Ubuntu 10.10 x64 on a MacBookPro 2,2 with Radeon Mobile X1600.
I try to change brightness of my screen but i discover that
/sys/class/blacklight is empty and there isnt /sys/class/lcd.
I read the dmesg and i found this 2 lines:
failed to evaluate ATIF got AE_BAD_PARAMETER
radeon 0000:01:00.0: Error during ACPI methods call
is a bug of the driver? i look for it in internet but i dont find anything...
