I also have been having trouble getting the drivers to install as well, so I thought I would attempt to resolve this for my System Once and for all. I have been at this all day and seem no closer to having resolved it. I have posted a Blog Entry @ http://busnet-serveradministration.blogspot.com/
fully describing what I have done today. Including attempting the above fix.
Please see it for the full description, I can not possibly post all of it here.
I am using Mint 13 Mate 64-bit, all system specs are in the blog, along with what inxi -Fxz reports
Briefly, I have an AMD HD 4670 Video card and have been attempting to use Jocky to install the proprietary AMD Drivers. Each time that I attempt this, and I have attempted it multiple times since the release of Mint 13 (I give it a try, give up and then clean install another Linux Distro for a while, then come back a month or 2 later for another try and always a clean install on each attempt), it throws an error message indicating that the installation has failed for the AMD Drivers. However, after the failed installation I have both the AMD CCC & AMD CCC (admin) Icons in Control Center and in the Main Menu.
In the Control Center and in the Menu, I can open the AMD CCC, In either location there is no response to attempting to open the AMD CCC (admin) Option. However I can run the AMD CCC admin option from Terminal with "sudo amdcccle" and it all seems to behave normally.
Compositing seems to be working as well, however I am getting Error messages from Minecraft and think this is a result of this driver problem.
I have the jocky.log files, as well as the Minecraft error logs.
Any Help would be so great, and if you read the full blog, you might even get a few diamonds
