Howtogeek posted a guide about adding proprietary drivers to Ubuntu 10.04

Does the hardware on your Ubuntu system need proprietary drivers work at peak performance? Today we take a look how easy version 10.04 makes it to install them.

Ubuntu 10.04 finally automatically recognizes and installs drivers for most hardware today, it even recognized and configured Wi-Fi drivers correctly every time in our tests. This is in contrast to the past, when it was often difficult to get hardware to work in Linux. However, most video cards still need proprietary drivers from their manufacturer to get full hardware video acceleration.

Even though Ubuntu doesn?t include any non-open source components, it still makes it easy to install proprietary drivers if you wish. When you first install and boot into Ubuntu, you may see a popup informing you that restricted drivers are available.
