[sjoeze]

Hallo,

I've installed Mountain Lion on my Sony Vaio VPCEJ2L1E.
Everything is working, except the brightness of my laptop screen.
I have a dsdt.aml with a device pnlf inside, but still it isn't working
Could somebody check my dsdt.aml?

Native brightness doesn't work for everyone, but... Do you have the brightness slider in your System Prefs -> Displays?

No, I don't have the brightness slider.
