Ubuntu Precise Installation Guide
Installing Catalyst Manually (from AMD/ATI's site)
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl + Shift + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).
Before you start
If you have previously attempted installing Catalyst, remove any leftover files by following the Removing the Driver section. Make sure universe and multiverse are enabled in your repository sources (System -> Administration -> Software Sources). or Applications->Ubuntu Software Center->Edit->Software sources->Other software: check canonical partners.
Install the prerequisite packages:
sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases linux-headers-generic xserver-xorg-core libgcc1
If you are using the x86_64 architecture (64 bit): 1. Install "ia32-libs" before proceeding!
sudo apt-get install ia32-libs lib32gcc1 libc6-i386
2. Create a symlink from /usr/lib64 to /usr/lib :
cd /usr ; sudo ln -svT lib /usr/lib64
Download the latest Catalyst package.
This package contains both the 32-bit and 64-bit driver.
cd ~/; mkdir catalyst15.12; cd catalyst15.12/ wget http://www2.ati.com/drivers/linux/amd-driver-installer-15-12-x86.x86_64.run chmod +x amd-driver-installer-15-12-x86.x86_64.run
Create .deb packages.
sudo sh ./amd-driver-installer-15-12-x86.x86_64.run --buildpkg Ubuntu/precise
It may take a while...
