I run Ubuntu 14.04 and I installed the ATI drivers from "Software Update" -> "Additional drivers", but on the official ATI website the latest Linux beta drivers have a newer version.
If that version supports kernel 3.13 can I download the drivers and install them from there since they are the latest?
The latest version of the proprietary ATI driver in Additional Drivers for Ubuntu 14.04 is fglrx-updates 13.3. fglrx-updates 13.3 supports the 3.13 Linux kernel. The latest version of the AMD Catalyst Driver for Linux from the AMD Graphics Drivers and Software website is 14.4. I don't think there's really much point in installing the AMD Catalyst Driver in Ubuntu 14.04 unless you tried the fglrx-updates driver first and found something wrong with it.
