EnvyNG: an easy way to install graphic drivers

What is Envy?:

"Envy" is an application for Ubuntu Linux and Debian written in Python and PyGTK which will:
1) detect the model of your graphic card (only ATI and Nvidia cards are supported) and install the appropriate driver. However automatic detection can be overridden with the "Manual installation"
2) install the right driver for your card and all the required dependencies
3) configure the Xserver for you

Envy features both a GUI (which you can launch only inside a Desktop Environment) and a textual interface which you can use if, for example, you cannot start the Xserver.

WARNING: you will have to remove the driver you installed with Envy before upgrading Debian or Ubuntu to a newer release (e.g. upgrading Ubuntu Edgy to Ubuntu Feisty or Debian Etch to Debian Lenny).

You will have to type the following command:

sudo envy --uninstall-all
[NOTE: This is no longer necessary with EnvyNG]
