How do I install the latest ATI Catalyst Video Drivers in Ubuntu 12.10 Quantal?

There are other threads related to this question for Ubuntu 12.04, however THEY DO NOT APPLY TO 12.10. This is not a duplicate of another thread if the referenced thread doesn't answer the question asked.

Solution 1:

For the purpose of this question: Catalyst = fglrx = proprietary AMD/ATI display driver

The most problems people are having come from the fact that:
1. Ubuntu has moved to newer driver versions, that don't support some older ATI/AMD chips
2. Ubuntu has moved to newer Xorg versions

Symptoms:
No. 1 - 'not supported' errors / Jockey not detecting proprietary drivers valid for installation
No. 2 - some older ATI/AMD Catalyst versions won't install

Which all comes down to:
Your chip is no longer supported by the latest ATI/AMD catalyst display drivers (be it via manual install or from Ubuntu repositories)

Solution:
Check, what is the latest driver version that supports your chip and then proceed with the installation accordingly.

Chips that are indicated 'legacy' (not supported for the latest Catalyst versions):

Solution 2:

Here is the latest version of Ati Catalyst 12.11 (beta) and 12.10 (stable) that has just been released ,you can find it here : http://www.upubuntu.com/search/label/System hope it will work .

Solution 3:

The latest ATI catalyst for Ubuntu 12.10 I know of is this one:
AMD Catalyst 12,9 driver

First Uninstall the current driver AMD with these commands:

sudo sh /usr/share/ati/fglrx-uninstall.sh 
sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev* xorg-driver-fglrx  

Manual installation:

To install AMD Catalyst 12.9 in Ubuntu 12.10/12.04/11.10 run the following commands from the terminal:

sudo apt-get install unzip
cd /tmp && wget -O amd-12.9-9.00-EDG_Direct.zip http://www2.ati.com/drivers/embedded/9.00-120815a-146426C-EDG_Direct.zip
unzip amd-12.9-9.00-EDG_Direct.zip
chmod +x amd-driver-installer-9.00-x86.x86_64.run 
sudo sh amd-driver-installer-9.00-x86.x86_64.run

And then after the installation was finished run this command:

sudo aticonfig --initial -f 

Then reboot.

Note: PPA has not been updated so far, but the driver will be updated soon. To install the driver provided by xorg-edgers, open the terminal and run the following commands:

sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get install fglrx-installer
