Bug Description
Ubuntu: 9.04
Laptop: Lenovo 3000 N100
uname: Linux lestaro 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux
Problems:
a) After upgrade to 9.04 jaunty laptop brightness cannot be adjusted properly:
* Fn + brightness+ switch between dark and less darker (look)
* Fn + brightness- turns screen darked, only one step available
b) Brightness applet is almost unusable: screen is heavy flickering all the time when adjusting brightness, just like mentioned in Bug #368506.
To fix: brigthness adjusting via Fn keys and via brightness apllet.

I have the same problem with the Fn brightness keys on my Lenovo SL300. The brightness applet, however, adjusts the brightness just fine, even though it can't actually get the current brightness.
