I know little of this, but, it's also only one graphics chip in use. Intel GMA 3150 if I get it right.
There is one netbook (and one display) in use and several different systems, they are: openSUSE (one of latests), Windows XP Pro x64, Tiny Core and iso-based Arch. I noticed some differences between colors in openSUSE (GIMP) and TC (fbcondecor splash daemon & also fbi viewer). I thought this was because of differences in png libraries versions... Maybe they decode the image in different ways... legacy and actual.
