ubuntu 16.0 安裝cuda
DL伺服器主機環境配置(ubuntu14.04+GTX1080+cuda8.0)解決桌面重複登入
參考部落格原址:http://www.cnblogs.com/Qwells/p/6086773.html#undefined
問題的開始在於:登入不了桌面,停留在重複輸入密碼介面
博文中分析的結論:
虛擬機器中不能直接呼叫物理顯示卡進行 CUDA 程式設計;虛擬機器中執行 CUDA 需要硬體和軟體的配合才能使用,對於一般使用者可能暫時不太可能的。

ubuntu14.04+cuda8.0(GTX1080)+caffe安裝
Ctrl+alt+F1進入字元介面,關閉圖形介面
sudo service lightdm stop //必須有,不然會安裝失敗
sudo /etc/init.d/lightdm stop //一樣的命令
sudo chmod 755 NVIDIA-Linux-x86_64-367.27.run //獲取許可權
sudo ./NVIDIA-Linux-x86_64-367.27.run //安裝驅動
Accept
Continue installation
安裝完成之後
sudo service lightdm start
圖形介面出現,然後關機,由讓人重複輸入密碼,登入不了
博主說
$ sudo /etc/init.d/gdm stop
$ sudo nvidia-installer --update
$ sudo /etc/init.d/gdm start
升級到375版本, 還是沒用,啟動進入不了桌面,重複登入
Install driver 367
Uninstall previous nvidia drivers.
$ sudo apt-get purge nvidia-*
Stop light gdm (graphical interface)
$ sudo service lightgdm
Go to tty (CTRL+ALT+F1). Set your init state to 3 (text only mode). It is important to do this. Note these commands on a paper or something. I experienced sometimes the tty does not show with the newest driver. I just ssh to my PC as a way around.
$ sudo init 3
Log in to tty and cd to the directory where your have downloaded the driver.
$ sudo ./NVIDIA-Linux-x86_64-367.35.run
It will ask if you want to install 32-bit libraries, say no (assuming you do not have a 32-bit OS, hopefully. If you do have a 32-bit OS it is a good idea to upgrade…)
In a few minutes it is done….smooth. Reboot your PC
$ sudo reboot
update 之後還是不能進 圖形介面
Uninstall previous nvidia drivers.
sudo apt-get purge nvidia-*
sudo apt-get autoremove
sudo apt-get --purge remove nvidia-*
remove 之後,
nvidia-smi
還是能看到gpu的。why?
解除安裝不了?
sudo apt-get install nvidia-prime
$ sudo /etc/init.d/lightdm stop
$ sudo nvidia-installer --update
$ sudo /etc/init.d/lightdm start
升級到375版本, 還是沒用,啟動進入不了桌面,重複登入
有人說,安裝必須要在安裝桌面前安裝GTX 1080 driver,後面方案驗證來看, 那個引數才是關鍵。
解決方法
利用sudo gedit /etc/modprobe.d/blacklist-nouveau.conf新建blacklist-nouveau.conf檔案,輸入命令
blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off
儲存並退出。這一步是為了禁掉Ubuntu自帶開源驅動nouveau。之後sudo reboot重啟系統。在終端執行命令
lsmod | grep nouveau
檢視nouveau模組是否被載入。如果什麼都沒輸出,則執行下一步。
根本問題在於 引數: --no-opengl-files
sudo /etc/init.d/lightdm stop
sudo ./NVIDIA-Linux-x86_64-375.20.run --no-opengl-files
sudo /etc/init.d/lightdm start
即可以正常登入介面了!!
在安裝過程中的選項:
Accept
Continue installation
register the kernel moudle sources with DKMS?
NO
Would you like to run the nvidia-xconfig utility to automatically update your X Configuration file so set the NVIDIA X driver will be used when you restart X?
NO
Install 32-Bit compatibility libraries?參考
NO
cuda8.0安裝
執行
sudo sh cuda_8.0.44_linux.run
選項如下所示:

===========
= Summary =
Driver: Not Selected
Toolkit: Installed in /usr/local/cuda-8.0
Samples: Installed in /home/c302
Please make sure that
- PATH includes /usr/local/cuda-8.0/bin
- LD_LIBRARY_PATH includes /usr/local/cuda-8.0/lib64, or, add /usr/local/cuda-8.0/lib64 to /etc/ld.so.conf and run ldconfig as root
To uninstall the CUDA Toolkit, run the uninstall script in /usr/local/cuda-8.0/bin
Please see CUDA_Installation_Guide_Linux.pdf in /usr/local/cuda-8.0/doc/pdf for detailed information on setting up CUDA.
***WARNING: Incomplete installation! This installation did not install the CUDA Driver. A driver of version at least 361.00 is required for CUDA 8.0 functionality to work.
To install the driver using this installer, run the following command, replacing <CudaInstaller> with the name of this run file:
sudo <CudaInstaller>.run -silent -driver
Logfile is /tmp/cuda_install_9045.log
設定環境變數
export PATH=/usr/local/cuda-8.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64:$LD_LIBRARY_PATH
新增系統變數修改到系統檔案
sudo vi /etc/profile
在最後新增上面兩句,然後儲存。使立即生效
sudo ldconfig //環境變數立即生效
