A new driver for owners of ATI graphics cards supporting Catalyst drivers released since a few hours. ATI AMD Catalyst 12.2 for Linux has no significant changes compared to the previous release (AMD Catalyst 12.1), and even AMD hasn't provided us with release notes for its driver dedicated to Linux to be able to know the new features and changes. However, one feature is only known in this latest release which is the support of X.Org Server 1.12.
In this tutorial we will help you install the ATI AMD Catalyst 12.2 driver under Ubuntu 12.04/11.04 or any older version of Ubuntu (11.04/10.10/10.04). If you prefer to install the driver manually, check this page.
Old AMD Driver Removal:
Before installing any new driver, you need first to uninstall the old AMD driver. Via the terminal, run the following commands to remove it:
sudo sh /usr/share/ati/fglrx-uninstall.sh
sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev* xorg-driver-fglrx
Note: If you receive errors when executing the first command, then skip it and move on to the second command.
