Perhaps it is because this is a headless system, but the solution was to uninstall the "fglrx" package and install just the "Non-X Support" Ubuntu 64-bit fglrx-core DEB package from the Catalyst driver download page: http://support.amd.com/en-us/download/desktop?os=Ubuntu+x86+64
- apt-get remove fglrx
- dpkg -i fglrx-core_14.501-0ubuntu1_amd64_UB_14.01.deb
- Reboot
Note: This could mean that either my custom build from the generic Linux 32/64-bit installer was bad or that a headless system simply should not have the "fglrx" ( Video Driver For Graphics Accelerators ) package installed. I will leave that determination up to AMD as there is sufficient information in this thread to reconstitute my environment and test the problem. Cheers.
