Ubuntu / Linux news and application reviews.

You can now reduce the wait for the latest graphic card driver in Ubuntu, which will only be available in a few months. There is an Ubuntu repository periodically updated with the latest open source drivers included in the xorg project.

Using this repository you will find improved video drivers for Intel, ATI, Savage and generic VESA driver. This repository is designed to support drivers from Ubuntu Hardy Heron up to the next generation of Karmic Koala.

To add this repository, go to System > Administration > Software Sources, click on the second tab: "Third-party Software", and add these:
deb http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu jaunty maindeb-src http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu jaunty main
and don't close Software Sources yet. If you want to add the repository for Intrepid or Hardy, replace the bolded text in the repositories above with either Hardy or Intrepid.

Now import the PGP key for this repository, using the following command:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 8844C542

Update: for Ubuntu Karmic or newer, run the following command instead (to add the xorg-edgers PPA):
sudo add-apt-repository ppa:xorg-edgers/ppa

Then go to System > Administration > Synaptic Package Manager and click the "Mark All Upgrades" button:


You should now restart the computer.

This repository is a further step of Ubuntu community in order to try to solve one of the problems that Linux users are more affected in the proper detection and operation of their graphics cards and also this may solve some problems regarding desktop effects, especially on Intel card, in individual cases where these drivers are placed in the Compiz.
