Lee Willis, I was having the very same issue with fglrx - corrupted display, barely usabe, clicking didn't work, even after barely possible to target what you wanted to click, etc.
However, I came to this fix that works - run Terminal with keyboard CTRL+ALT+T and do sudo su and then xrandr --output VGA1 --auto --right-of LVDS1 --output VGA1 --auto --scale 1.0001x1.0001
After that, everything becomes usable again. However, this does NOT fix the issue with random switching of resolutions/monitors/mirroring! That is still present.
Now, I am testing with Ubuntu 14.04 for my bug report and will provide feedback when I have used it for long enough.

Oh, Christopher M. Penalver, I have seen your info that this laptop had new BIOS released - the A12 and I flashed it today. I still had the exact same problem on Ubuntu 13.10 (saucy) and as I said, I will report (in my bug report) how version 14.04 goes...
