fglrx-core kernel module failed to build

[Solitaire]

Using "Additional Drivers" tab from "Software & Updates" to change my graphics from the Propriety fglrx-updates To "xserver-xorg-video-ati" Open source drivers.

Upgrade failed and now showing I'm using "fglrx" rather than the open souce or fglrx-updates drivers.
