Maximize windows in OsX

The maximize button (top left – 3rd button to the right on the window) hides the top bar and dock automatically in OsX.  If you want to make a window cover the whole screen without covering the dock and top bar, use the following key combinations:

Option + (click on green button on top left) – This maximizes the window vertically, useful for some apps that dont require as much horizontal space

Shift + Option + (click on green button on top left) – This maximizes the window to cover both horizontal and vertical space

Getting the Latest Ubuntu Graphics Drivers on Samsung NC20

Official Ubuntu circle with wordmark. Replace ...
Image via Wikipedia

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).
{adinserter 2}
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.

The latest version of (k)Ubuntu comes with a Netbook OS to suit the small screen and moderate horsepower netbook segment of notebooks. The version is light weight and makes good use of the features common between netbooks to get the best out of your netbook.

The official websites recommend you download the iso and create a bootable flash drive using the iso. The step by step method to do it is given in the following links:
Ubuntu – Netbook Remix
KubuntuNetbook Technical Preview


If you are like me and dont want to go thru the process of installing Karmic Koala again, you are in luck… You can test the new Netbook Remix directly from the default desktop install of Ubuntu/Kubuntu.

If you are using Ubuntu you just have to install the “ubuntu-netbook-remix” package. That can be done with the following command:
sudo apt-get install ubuntu-netbook-remix

If you are using Kubuntu you just have to install the “kubuntu-netbook” package. That can be done with the following command:
sudo apt-get install kubuntu-netbook

When you reboot and login you will automatically be taken to the netbook remix of your OS.

PS: The version is one of the earliest releases, so expect updates and more improved performance in the near future.
