I just installed Oneiric on a SAMSUNG NP300V3A (Series 3) laptop. Everything seems to work fine more or less except one thing:

I can't reduce screen brightness more than 10% or so. Fn+F3 (brightness up) sets brightness to 100% and Fn+F2 (brightness down) sets it to about 90% or so. No matter how many more times I press it, it doesn't fall below that. For a video card I have an integrated Intel HD Graphics 3000 chipset, but that's probably unrelated to the issue.

What can I do to solve this?

Why does my laptop resume immediately after suspend?

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I seem to be having some problem with suspend mode. Every time I try to suspend my laptop, it just locks the screen. Or maybe it successfully suspends just to resume only an instant after. What could cause such a behaviour? I'm running 32-bit Ubuntu 12.04 with the 3.2.0-25 kernel on a HP dv5-1178er… >>> More
