Ubuntu – Differences between the 2 FGLRX graphics drivers

fglrx

I currently installed Ubuntu 11.10 and when I am prompted to install Additional Drivers, I get confused on which to use between the 2 FGLRX graphics drivers:

  • ATI/AMD proprietary FGLRX graphics driver (post-release updates)
  • ATI/AMD proprietary FGLRX graphics driver

These 2 appear but I am not sure what to choose. Previously, on 11.04, only the latter appears (the one without the post-releae updates).

What's the difference between these 2 drivers?

Best Answer

The 'post release updates' will install Catalyst 11.9 which is the latest version while the 'ATI/AMD proprietary FGLRX graphics driver' will install Catalyst 11.8 which was the driver at the freeze stage of 11.10 development

There has been issues with the 11.9 driver with Unity (see ubuntu forums here) so I suggest you install the 'ATI/AMD proprietary FGLRX graphics driver'.
