I bought a Sony Vaio with windows 7 preinstalled. Now I have a lot of problem installing Ubuntu, but I was able to install Ubuntu, but now the brightness doesn't work as needed.

With lspci I get:

VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Thames [Radeon 7500M/7600M Series]

How can I solve this ?

Too much light is hurting my eyes, the brightness is at maximum level and I use the computer to work.

Try installing xbacklight using apt-get (sudo apt-get install xbacklight). Then try this from the terminal, too: xbacklight -20. If brightness is decreased when running this last command, then this solution might work for you: How to use xbacklight with brightness keys in a VAIO (you'll need to edit some of the paths inside the script).

Hope it helps.
