How do I improve GUI performance on AMD E2-3200 APU?

I have an AMD E2-3200 APU (integrated Radeon GPU in CPU), running Ubuntu 12.10 (generic Ubuntu image, Linux 3.5 kernel).

My ubuntu works too slow on GUI related process. I wonder what is the best to do to get better performance here?

lshw -c video shows that it uses radeon driver. ps -ef | grep compiz shows that it uses Compiz. I did metacity --replace to disable Compiz, however the GUI was not usable after executing that command (desktop and folders disappeared, window's menu and GUI related buttons disappeared).

From your problem description I get that you're using the default Ubuntu graphical environment - Unity - which is performing poorly on your video card.

If the suggestion of installing fglrx doesn't work/provide the required performance, please read below.

If you don't necessarily want to run Unity, the best idea that comes to my mind is to try an alternate graphical environment - XFCE or LXDE - which is much lighter than Unity on graphical resources.

I run a (custom, built on my own) XFCE/LXDE version successfully on systems with Pentium 4 CPU, 512 MB RAM and integrated Intel 82865G graphics card. The Intel 82865G graphics card is a very old & poor performance video card. Oh, I should also mention I'm running as LiveUSB (which eats some additional RAM).

While you could install only the parts required to run a XFCE/LXDE session, I think it's easiest to install the full desktop experience for Xubuntu/Lubuntu. Please know there won't be a huge volume of data to be downloaded as most part of the system is already there, only specific packages will be downloaded.

You can get XFCE/Xubuntu or LXDE/Lubuntu easily by running sudo apt-get install xubuntu-desktop or sudo apt-get install lubuntu-desktop in a terminal (CTRL+ALT+T).
After that, logout and login back in, and remember to change the session from Ubuntu to Xubuntu/Lubuntu at the login screen.

Good luck and let us know if this works!
