When you open Ubuntu 12.04 just connect your system to internet and open Additional Drivers application........And it shows graphics driver for your system......From there you can install those drivers and after that you have chance of decreasing brightness.....

I am using VAIO E-Series lapi and I am also having the problem of Bluetooth.....
