Alienware-17-R4，Ubuntu16.04安装cuda8.0

 InstallingCUDA 8.0 on a fresh installation of Ubuntu 16.0

(tested on Alienware-17-R4，i7 7820hk，Gtx-1080)

1.  Launch [Software& Updates]. Select [Additional Drivers] tab.

2.  In the list, findyour graphic card. Among the drivers that can be used for the card, choose theproprietary driver from NVIDIA. Then press [Apply Changes] button. In my case,under the graphics card name "NVIDIA Corporation: GM107M [Geforce GTX950M]", there were two selections:

·       Using NVIDIAbinary driver - version 375.66 from nvidia-375 (proprietary, tested)

·       Using X.Org Xserver - Nouveau display driver from xserver-xorg-video-nouveau (open source)

3.  Delete defaultinstalled video drivers with $ sudoapt remove xserver-xorg-video*.

4.  Reboot.

5.  Download CUDA8.0 Toolkit from here. Among the installer types, choose "runfile (local)". Thisdownloads cuda_8.0.61_375.26_linux.run.

6.  Run theinstaller with $ sudo shcuda_8.0.61_375.26_linux.run.

·       [Optional] Ifyour currently installed NVIDIA driver version is higher than the driverversion contained in the downloaded installer, you can choose not to installthe driver while installing CUDA. In my case, since I already have driverversion 375.66, which is higher than 375.26contained in the installer, I chose not to install.

7.  After install,config your binary path and library path (You can follow the directions fromthe instller). If you choose to configure ld.so.conf and the following erroroccurs: libEGL.so.1 is not asymbolic link, follow the direction from this link.

8.The laststep of installation CUDA is to add the path of it to source bash file:

sudo gedit~/.bashrc

The the twofollowing line must be added to the file with regard to CUDA 8.0 installation:

exportPATH=/usr/local/cuda-8.0/bin:$PATH

exportLD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64:$LD_LIBRARY_PATH
