This means there's no proprietary graphics driver for your ATI
graphics and this kernel available.

Update the package linux-image-lowlatency, since headers for
3.13.0-66-lowlatency aren't available anymore by official repositories
and install the linux-headers-lowlatency package that fits to the
version of the image. Usually dkms should build the new modules
(driver) but I don't know how it's handled for Ubuntu trusty, so take a
look at the Wikis.

FWIW, I'm using the open source driver for my Wily install, since ATI
doesn't care much about Linux compatibility. NVIDIA usually allows to
build the proprietary driver against all kernel versions and all X
versions, but ATI is limited to a few X versions. Soon or later it
becomes impossible to build the proprietary kernel modules, because the
source code doesn't fit to the installed version of X and model of
your graphics.

The "radeon" driver might not fit to the requirements needed to run
GNOME3, but even Google-Earth can be used without performance issues.

IMO you should switch from "fglrx" to "radeon", so you never need to
care about issues with a proprietary driver.
