Ubuntu 11.04 "Natty Narwhal" Linux OS Released

"Form and function are a unity, two sides of one coin. In order to enhance function, appropriate form must exist or be created."
   -Ida P. Rolf

The Ubuntu team is pleased to announce Ubuntu 11.04, code-named "Natty Narwhal". 11.04 continues Ubuntu's proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution.

To learn more about Ubuntu, check out Beginning Ubuntu Linux book from Apress.

For PC users, Ubuntu 11.04 supports laptops, desktops and netbooks with a unified look and feel based on a new desktop shell called "Unity". This version supersedes Ubuntu Netbook Edition for all PC netbooks.

Developer reference images are provided for select Texas Instruments (TI) ARM platforms, specifically the "PandaBoard" and "BeagleBoard".

Ubuntu Server 11.04 has made it easier to provision servers, and reduce power consumption.   Ubuntu Server 11.04 for UEC and EC2 has a new kernel and improved initialization and configuration options.

KDE 4.6 Graphics Glitches / Screen Refresh Bug Fix for Intel/GMA VGA Card

The redraw of many widgets when using the KWin doesn’t work correctly:

  1. In Firefox if I scroll down the page, the page is not redraw correctly. I have to move the mouse all over the page to remove the broken text.
  2. Shell window is not updated properly

If you have experience these symptoms with KDE 4.6 under Ubuntu 10.10 Maverick Meerkat with an Intel graphics card, then there is a quick fix:

sudo add-apt-repository ppa:glasen/intel-driver sudo apt-get update && sudo apt-get upgrade

It fixed it for me at least.
My intel graphics card on Asus U35JC:

00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18)
