I'm running FC15 on a laptop with core i5 and a radeon HD5760. I love GNOME3 but I'm getting more and more annoyed by my fan running all the time and the bad graphical perfs (especially on minecraft which is heavily laging) due to the ATI open source drivers.
Since there's no solution about the driver problem yet, I'd like to install KDE until a solution is found. This means that I'd like to keep my GNOME3 installed if possible, and I don't want to mess with my laptop because I need it to work.
Could you please help me to proceed with the installation of KDE ?
