SYSTEM SETTING => Additional Drivers => 更新，發現有兩個驅動可更新，第二個多了（post-release-updates）就始終安裝有問題。
在網上搜尋結果如下：
1、sudo apt-get install fglrx fglrx-amdcccle
2、sudo apt-get install build-essential cdbs dh-make dkms execstack dh-modaliases fakeroot libqtgui4
3、wget http://www2.ati.com/drivers/linux/amd-driver-installer-catalyst-12.10-x86.x86_64.zip
unzip amd-driver-installer-catalyst-12.10-x86.x86_64.zip
chmod +x amd-driver-installer-catalyst-12.10-x86.x86_64.run
4、sudo sh ./amd-driver-installer-catalyst-12.10-x86.x86_64.run --buildpkg Ubuntu/precise
sudo dpkg -i fglrx*.deb
5、sudo amdconfig --initial -f
PS：對於64位的話，經測試成功，就在2和3之間插入sudo apt-get
install lib32gcc1
