I just installed fedora 20 on my second pc and its running pretty hot, I found a driver on the site http://support.amd.com/en-us/download/desktop?os=Linux%20x86_64.I unpacked it and I tried sudo sh amd-driver-installer-13.35.1005-x86.x86_64.run and I get this Supported adapter detected.Check if system has the tools required for installation.fglrx installation requires that the system have kernel headers for 3.7 release./lib/modules/3.11.10-301.fc20.i686+PAE/build/include/generated/uapi/linux/version.h cannot be found on this system.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 --force option to install without the tools.Forcing install will disable AMD hardware acceleration and may make your system unstable. Not recommended.and I don't know how to solve it and I have already tried: yum install kernel-devel kernel-headers gcc -yhttp://www.amd.com/US/PRODUCTS/NOTEBOOK/GRAPHICS/7000M/7400M/Pages/radeon-7400m.aspx
