Ubuntu 12.04: Missing RAM and Unsupported hardware driver issue

Question

I've just install ubuntu 12.04 64-bit on my new PC:
MoBo: Gigabit F2A75M-D3H
CPU: AMD A6 5400K
Ram: 2*4GB

1st problem
From BIOS, I can see 4096 MB RAM installed but from System Monitor are detected only 3.3 GiB.

2nd problem
in a bottom right corner, appear a logo "AMD Unsupportde hardware". I've tryed to follow some procedure (sudo apt-get install fglrx-updates --- then reboot) but doesn't disappear.

Ubuntu find drivers by it-self, "fgrlx ATI/AMD" and ""fgrlx ATI/AMD" post-release" but I can install only the first... the second one, failed during installation procedure.

Do you have any Ideas?

Answer 2

1. Missing RAM

   Your mother board has on board video card. Those "missing" memory are assigned to your video card. The amount should be changeable in bios.

2. Driver for Unsupported Hardware

   I do not have ATI/AMD video card around to test. However, my guess is you only need to install one driver, assuming both are video card driver.
