I have a Samsung NC10 with Ubuntu. It worked well (in the begining with 9.10) with your specific packages but since a while I have problem with brightness setting (Fn + Arrow up or down).
i upgrade to Lucyd and I still have the following problem :
The screen besomes suddently totaly white. I have to slow down brightness below approx 50% to view the screen.
A totally white screen might be a hardware error too.
The NC10 has some Problems with the display/display cable.
just google something like NC10 white screen to find more infos
