I have a Dell Studio xps 1640. It has an AMD Radeon HD 4600 series graphics card.
I looked up the common heat issues and it said that usually the graphics driver is to blame and once the proprietary is installed it gets fixed.
Ive tried to install the proprietary drivers from AMD and when I install Catalyst and reboot I can't get to my desktop anymore. Unity doesn't load and I am forced to uninstall the driver via the command line in order to get things working again. I think it is a common issue right now but any idea what I should do?
