There appears to be two available drivers for Ubuntu 14.04:
"AMD Catalyst™ 15.5 Proprietary Ubuntu 14.04 x86_64 Video Driver for Graphics Accelerators"
"AMD Catalyst™ 15.5 Proprietary Ubuntu 14.04 x86_64 Minimal Video Driver for Graphics Accelerators (Non-X Support)"
What is the difference between these two drivers and which one should I use? The "Minimal" driver is 8Mb larger than the regular driver.....
