支援顯卡列表：
RadeonDriver - Community Ubuntu Documentation



移除已安裝的 ATI 驅動：

# sh /usr/share/ati//fglrx-uninstall.sh 

# apt-get purge fglrx*
# apt-get purge xserver-xorg-video-ati xserver-xorg-video-radeon

 
安裝開源驅動：

# lspci -v | grep VGA
# apt-get install xserver-xorg-video-ati  # which installs xserver-xorg-video-radeon by dependency. 
# apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core  #

libgl1-mesa-dri will automatically be installed as a dependency of the xserver-xorg-core

# dpkg-reconfigure xserver-xorg
