其实写出本文没有多少技术含量， 只是让新手少走弯路。大牛勿喷！

安装Debian 8后第一件事就是安装显卡驱动

sudo dpkg --add-architecture i386

sudo aptitude update

sudo aptitude install make gcc

sudo aptitude install build-essential

sudo aptitude install linux-headers-$(uname -r)

sudo aptitude install fglrx-driver fglrx-atieventsd fglrx-control fglrx-modules-dkms glx-alternative-fglrx amd-opencl-icd

sudo aticonfig --initial

事实证明，开源驱动安装后是进不了图形界面的～(不要打我。。。)

接着来， 先看下你的AMD/ATI显卡型号 (这是我显卡驱动安装成功后的)

可以看到[Radeon HD 6630M/6650M/6750M/7670M/7690M]

$ lspci | grep VGA

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Whistler [Radeon HD 6630M/6650M/6750M/7670M/7690M]

然后进入AMD官网根据显卡型号下载驱动

http://support.amd.com/zh-cn/download/

下载后amd-catalyst-15.9-linux-installer-15.201.1151-x86.x86_64.zip文件，

解压后是AMD-Catalyst-15.9-Linux-installer-15.201.1151-x86.x86_64.run，

直接

sudo chmod 777 AMD-Catalyst-15.9-Linux-installer-15.201.1151-x86.x86_64.run

sudo ./AMD-Catalyst-15.9-Linux-installer-15.201.1151-x86.x86_64.run

然后会出现图形界面，一步一步安装即可，安装完成后会提示重启

首先可以看到

图形那里已经是AMD Radeon 6600M and 6700M Series

说明显卡驱动已经安装成功了

接着测试显卡性能

$ fglrxinfo

display: :0 screen: 0

OpenGL vendor string: Advanced Micro Devices, Inc.

OpenGL renderer string: AMD Radeon 6600M and 6700M Series

OpenGL version string: 4.5.13399 Compatibility Profile Context 15.201.1151

$ fgl_glxgears

Using GLX_SGIX_pbuffer

2151 frames in 5.0 seconds = 430.200 FPS

2040 frames in 5.0 seconds = 408.000 FPS

去试试吧， 伙伴们！

最后上一张我配置的Debian 8，主题是Paper
