To get the best graphics performance out of your Samsung NC20, you will need to install the latest graphics drivers.  These drivers unfortunatey are not easy to find on the web, so here is a step-by-step installation instructions for driver installation on Ubuntu 10.10.  Special thanks to the wonderful folks at Ubuntu Forums(Wonderful source, thumbs up to the contributors).

The steps explained below were taken from post #542 from this Ubuntu Forums page.

  1. Download this zip file via_chrome9_drv_u1010_v2.zip and unzip it
  2. Open a terminal window and change into that directory (“cd ~” for home dir)
  3. Install the “dkms” package from Ubuntu package repository
    $ sudo apt-get install dkms
  4. Install the kernel driver:
    $ sudo dpkg -i chrome9-drm_87a.55689-maverick1_all.deb
  5. Install the X.org driver:
    $ sudo dpkg -i --force-confmiss --force-confnew xserver-xorg-video-chrome9_87a.55729-maverick1_i386.deb
  6. Update /etc/X11/xorg.conf file
  7. Copy the provided xorg.conf.nc20 file to xorg.conf
    $ sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
    $ sudo cp /etc/X11/xorg.conf.nc20 /etc/X11/xorg.conf
  8. Reboot Ubuntu
  9. Check if it’s working: Open /var/log/Xorg.0.log in a text editor. If you see several lines containing “VIA(0)”, then the new driver is being used.

Also note:

  • The sample xorg.conf.nc20 is only installed if you add the “–force-confmiss –force-confnew” options to dpkg.
  • Although VIA marks the source code this hacked driver is based on as stable, I cannot guarantee it to be bug-free. Use with caution.

Apt-Get: Fixing GPG Error

While updating a Debian based system, you may encounter an error as follows:

W: GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 2836CB0A8AC93F7A

This is a feature of the apt-get package manager that checks the authenticity of servers while updating Debian. It just means that the system is unsure if the repository it listed is safe to receive updates from.

To fix this problem (provided you are sure that the repository is safe), all you need to do is execute the following commands with the pubkey you received in the error:

gpg --keyserver pgpkeys.mit.edu --recv-key 2836CB0A8AC93F7A
gpg -a --export 2836CB0A8AC93F7A | sudo apt-key add -

From now on Apt-Get will recognize that repository and not give you a GPG error.
