I had a Samsung N150 from the office and installed it with Kubuntu 11.04 not long ago. Below are some notes to get it working acceptably. It's more of a high level notes/todos on setting things up for guides and reminder and not meant for the detailed to-the-letter instructions (read : familiarity with ubuntu/linux is assumed).
- The basic installation. There is nothing special here as it went quite straightforward.
- Changing the network-manager with wicd. My wifi can not be connected with the defallt-installed network-manager. Removing network-manager and replacing it with wicd (together with it's kde integration) solve the problem.
- Add xorg-edgers to apt-source and do updates to get video driver hardware acceleration (http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu natty main). This way, the 3d efffects on kde will run smoothly.
- Fix the brightness setting : https://bugs.launchpad.net/ubuntu/+source/udev/+bug/574250. Installing samsung-backlight and samsung-tools mentioned on the article does not help in my case (only working once after install and the brightness setting fail to work again after resboot). The solution I end up settling in is making script to encapsulate the solution using setpci as referred on the article. It is not user friendly but good enough for me and since I don't change brightness too often it i not really a big deal.
