I used ATI fglrx driver for 12.04 with ATI Radeon HD 3200. After upgrade to 12.10 - there is no fglrx and the system uses standard opensource ATI driver. The driver is very slow especially on playing movies (including flash movies) and on scrolling web pages.

I attempted to install fglrx* packages but fglrx in the version 2:9.000-0ubuntu3 (Catalyst 1.12.8) does not support HD 3200 anymore.

I attemtped to install http://www2.ati.com/drivers/legacy/12-6/amd-driver-installer-12.6-legacy-x86.x86_64.zip which seems to be most recent version supporting HD 3200. But it fails on kernel module compilation without any meaningful messages in logs.

Moreover, AMD unofficial wiki states that drivers < 1.12.8 do not support kernel 3.5 and xserver 1.13. See also the comment below.

My exact lspci hardware info:

01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS780 [Radeon HD 3200]

So the question is: how to diagnose performance issue with open source driver for HD 3200 and tune it to get better performance in everyday usage like movies and page scrolling?

As I also have found out (4850 here), you can't via any method install fglrx-legacy on stock ubuntu 12.10, even if you use catalyst 12.6 which supports our cards, because the x server that 12.10 uses (1.13) is not supported by catalyst 12.6 or older.

However, this is somewhat of a solution, that I can confirm works on my machine: http://www.ubuntuvibes.com/2012/10/how-to-install-amd-catalyst-legacy.html

Just follow that (well, uninstall any fglrx you have installed now first), and you should have a better experience.

I should note, you will be downgrading your x server to version 1.12, and these packages are not supported by ubuntu, but this is the closest to a "solution" as can possibly exist at this time.
