Kubuntu Jaunty on Samsung NC10

April 25th, 2009

A while ago I posted about how one can install Kubuntu on a netbook without cd-rom device. Although there were some issues on the NC10 still it worked pretty neat. Two days ago Kubuntu Jaunty (9.10) was released. I updated my NC10 with this version and this is what I discovered:

  • Video artifacts in KDE login screen disappeared
  • Speakers are muted when plugging in earphones
  • Getting Wifi to work is a lot harder than the old Kubuntu version (especially 802.1x). I have to use knetworkmanager to make it work (sometimes it does not work at all).
  • The screen brightness can be set with the slider of the energy widget.

Disable root login for ssh server in Kubuntu

February 13th, 2009

If you are a hacker, what is the thing you want to be on a Linux System? Root. You can try to access a ssh server with the root user. There is an option in the ssh server configuration which prevents a remote root login. This does not mean you can not become root, it means no one can directly login as the root user. So if you are logged in as Alice you can simple enter the “su” command to become root.

How we can prevent the remote root login is described below.

Install vmware-player on Kubuntu

February 4th, 2009

Next semester I need to code some programs for MINIX 3. Since I do not want to install this operating system on one of my machines I decided to use VMWare. The VMWare Player is free, and can be easily installed on Linux. At least that is what I thought…

Samsung NC10′s Kubuntu finally mutes speakers when using headphone

January 29th, 2009

When I bought my Samsung NC10, I noticed some weird behaviour of the sound card; when I plugged in my headphone the speakers still played sound as well. This morning I updated my Kubuntu running Samsung NC10 with a new kernel: 2.6.27-11-generic. After a reboot  I noticed I finally had a headphone slider in KMixer.

Samsung NC10′s webcam works on Kubuntu!

January 25th, 2009

Lately I was wondering if my Samsung NC10′s webcam worked under Kubuntu 8.10. I found this website which shows a tool called luvcview in order to show your webcam video. In order to install luvcview execute the following command:

# apt-get install luvcview

When the installation is done simply execute:

$ luvcview

Smile! :)

Webcam works!

Install Kubuntu 8.10 on a Samsung NC10 (and other cd-rom less devices)

January 8th, 2009

As posted here I recently bought a Samsung NC10. It comes with Windows XP preinstalled, but I liked to have Kubuntu 8.10 installed as well. The Samsung NC10 is equipped with a 160GB harddisk so there is plenty of space (at least for me). So I started to figure out how I could install Kubuntu 8.10 on a netbook with no cd- nor dvd-drive. In this post I describe how I managed to solve these problems.
