EnvyNG

Envy is a Linux application designed for Debian and Ubuntu operating systems, crafted with Python and PyGTK. This software is profound in providing the following features for users; detecting the graphic card model you use, where only ATI and Nvidia cards are supported while installing the appropriate driver. In situations where automatic detection doesn't suffice, manual installation serves as an option.

Another feature of Envy is its capability to package the driver that comes with ATI or Nvidia's installer from their websites. Furthermore, this application installs all requirements that are needed for proper packaging and driver installation, configures the Xserver configuration files according to the user's preference.

Envy has a Graphical User Interface (GUI) launched only inside a Desktop Environment for comfortability, while also featuring a textual interface for users who cannot start the Xserver. It's vital to note that this software comes with a WARNING message. The user must remove the installed driver 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).

Thus, Envy is a remarkable piece of software with its impressive features and warnings for system upgrades. It makes the driver installation and configuration process much more comfortable and provides appropriate solutions to any graphical driver-related issues on your Linux OS.
