Problem with ATI Catalyst Drivers in Ubuntu 13.10

Question

Recently I've installed Ubuntu 13.10 alongside Windows 8 (dual boot). My Laptop is Dell Inspiron 15, with AMD Radeon HD 7670 Video Card.

Without fglrx my expected battery life is reduced to 1:30 hrs from 3:30 hrs (In Ubuntu 13.04 but very slow booting).

So I installed fglrx using this answer.

But the problem is as you all know, Black Screen after logging into Ubuntu.

Tried so many solutions for this like reinstalling unity, ubuntu-desktop, compizconfig, etc. But none helped except removing fglrx* completely. (But I need them very badly due to battery)

PS. For those who think this question is a duplicate. Though the question may be a duplicate, but the answer is not!

Solution

Try installing the BETA drivers. Ubuntu 13.10 is using Xserver 1.14 (supported by AMD BETA Drivers) and as far as I know the official drivers' support Xserver up to 1.13.

Using the automatic install using that setup file has worked for me or you can use the same guide that you referenced in your question.

Fortunately, I've been trying on the same beta drivers that you linked in your answer from 2 days :(

Continuously getting the error message that "Downloaded file contains errors" though it is not even starting the download

Anyway, installing the ATI Driver also will reduce the battery usage, my battery can last 2Hour with Internet usage. I installed fglrx before, but is not that good, I had problem switching to the Intel Graphics too. Just get the latest Driver from AMD and install.
