I tried to install the ATI catalyst driver 13.4 on my ASUS X55U with Radeon HD 6320 and Ubuntu 13.10 (saucy). I tried... and it failed.

But, the good news is (it took me a few hours): Install the beta driver! That works!

Follow these install instructions and use the beta driver instead of the 13.4.
You can start downloading the beta here.

Good luck!
