I have Lenovo V570 laptop. i have tried different kernels 2.6.38, 2.6.39
but on all of them I can't change the bightness of the screen.
How about newer 3.0 images? do they work?
thank you.
The 3.0 kernel doesn't change anything. Brightness still doesn't change.
In that case please test against experimental 3.1-rcX
thank you
It works with the last experimental kernel (3.1-rc4)!!! The brightness
changes but there are still messages in dmesg:
