http://askubuntu.com – I just installed Ubuntu on my Samsung series 3 laptop with an AMD A6-3420M with Radeon HD 6520g graphics, and I am trying to install the flgrx experimental driver. However, I can not find the experimental driver, and when I use the stable version of that driver, the top bar does not show and the Unity launcher does not show up. On top of that, when I try to install the AMD drivers from the AMD site, it gives me the error One or more tools required for installation cannot be found on the system. Install the required tools before installing the fglrx driver. Optionally, run the installer with t (HowTos)
