I'm in the same situation, with Ubuntu 14.04.3 and fglrx-updates.
Tried the instructions in comment #18 but did not change anything. The log file is attached. Also tried removing and reinstalling fglrx, to no effect.
Problems seemingly started when I booted without the GPU (using Intel iGPU) to test hardware and again with the GPU. Before that fglrx was working fine.
