How does the fglrx package's version relate to AMD's version numbers, like Catalyst 12.3?

When I learn about a new version of AMD's graphics driver, I usually see something like "Catalyst 12.3." However, the fglrx package in Ubuntu has a version like 2:8.960-0.

Are these two version numbers related? How can I find the (better-known) official version number, like 12.3, for the fglrx package in Ubuntu's repository? Can I do this without needing to install the package?

Solution 1:

Unofficial AMD Linux Driver Wiki has the driver version on the release pages. e.g. Catalyst 12.3:

Revision Number: 12.3 (8.951)

Alternatively the Catalyst RSS Feed for Microsoft Windows also contains the driver information.

Catalyst 12.3 released for Windows. Available at
