Brightness control on Ideapad u350
I recently bought an Ideapad u350 and have installed Ubuntu 9.10 on it. Everything works out of the box, except for brightness control. I have tried Fedora 11 and Ubuntu 9.10 Alpha 3, and neither have working brightness control in any way (fn keys, applets...). I can set the brightness while the laptop is booting up, but after linux loads, it's stuck. Any ideas?
