* Pre-radeon - Cards older than the original Radeon 7000 (such as the Rage cards) have no 3d acceleration available.

• Radeon R100 to R200 - Cards in this range (Radeon 7000 to Radeon 9250) should use the open source ati driver which is the default on Ubuntu. This driver provides full 3d acceleration and is fully capable of running a composite manager. Older versions of fglrx (in 6.10 and older) supported the r200 series (Radeon 8500+), but it is practically impossible to use this driver on 7.04 (Feisty), and there is very little reason to do so.
• Radeon R300 to R400 - For cards in this range (Radeon 9500 to Radeon X850), you have a choice between the open source ati driver and the ATI restricted driver (fglrx).
• Fglrx provides faster and more complete 3d acceleration, better resolution support (particularly for LCD displays), and TV-out support. However, fglrx has a number of serious bugs that may make normal desktop usage unpleasant.
• If you wish only to run a composite manager, the free driver may be a better choice than fglrx because it supports AIGLX, which allows you to use compiz/beryl simply and painlessly. It is important to note that, unlike the free driver for older radeons, the the free driver for this series was written through reverse-engineering without access to hardware specifications (and with no assistance from ATI). This means that the quality of this driver varies greatly by model, and the only sure way to know that it will work well is to try it.
• Radeon Xpress Series (RS480) - For this series you must use fglrx to gain 3d acceleration because of its unique memory architecture. As of feisty, the free ati driver does not yet support it, although significant progress is being made for future releases
• Radeon R500 - Radeon X1000+ cards have no support at all (not even 2d) in the free ati driver, so you must either use vesa (a generic driver) or fglrx.
