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.
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.
