DL服务器主机环境配置(ubuntu14.04+GTX1080+cuda8.0)解决桌面重复登录

DL服务器主机环境配置(ubuntu14.04+GTX1080+cuda8.0)解决桌面重复登录

前面部分是自己的记录,后面方案部分是成功安装驱动+桌面的正解

问题的开始在于:登录不了桌面,停留在重复输入密码界面

博文中分析的结论:
虚拟机中不能直接调用物理显卡进行 CUDA 编程;虚拟机中运行 CUDA 需要硬件和软件的配合才能使用,对于一般使用者可能暂时不太可能的。

参考博文:

深度学习主机环境配置: Ubuntu16.04+Nvidia GTX 1080+CUDA8.0

深度学习主机环境配置: Ubuntu16.04+GeForce GTX 1080+TensorFlow

ubuntu14.04+cuda8.0(GTX1080)+caffe安装

如何搭建一台深度学习服务器

Ctrl+alt+F1进入字符界面,关闭图形界面

sudo service lightdm stop //必须有,不然会安装失败 
sudo /etc/init.d/lightdm stop //一样的命令

sudo chmod 755 NVIDIA-Linux-x86_64-367.27.run  //获取权限
sudo ./NVIDIA-Linux-x86_64-367.27.run  //安装驱动

Accept
Continue installation
安装完成之后

sudo service lightdm start

图形界面出现,然后关机,由让人重复输入密码,登录不了

博主

$ sudo /etc/init.d/gdm stop
$ sudo nvidia-installer --update
$ sudo /etc/init.d/gdm start

升级到375版本, 还是没用,启动进入不了桌面,重复登录

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 之后还是不能进 图形界面

Uninstall previous nvidia drivers.

sudo apt-get purge nvidia-*
sudo apt-get autoremove
sudo apt-get --purge remove nvidia-*

remove 之后,

nvidia-smi 

还是能看到gpu的。why?

卸载不了?

sudo apt-get install nvidia-prime

$ sudo /etc/init.d/lightdm stop
$ sudo nvidia-installer --update
$ sudo /etc/init.d/lightdm start

升级到375版本, 还是没用,启动进入不了桌面,重复登录

有人说,安装必须要在安装桌面前安装GTX 1080 driver,后面方案验证来看, 那个参数才是关键。

解决方法

利用sudo gedit /etc/modprobe.d/blacklist-nouveau.conf新建blacklist-nouveau.conf文件,输入命令

blacklist nouveau

blacklist lbm-nouveau

options nouveau modeset=0

alias nouveau off

alias lbm-nouveau off

保存并退出。这一步是为了禁掉Ubuntu自带开源驱动nouveau。之后sudo reboot重启系统。在终端执行命令

lsmod | grep nouveau

查看nouveau模块是否被加载。如果什么都没输出,则执行下一步。

根本问题在于 参数: --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

即可以正常登录界面了!!

在安装过程中的选项:

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?参考

NO

cuda8.0安装

运行

sudo sh cuda_8.0.44_linux.run

选项如下所示:

Description

This package includes over 100+ CUDA examples that demonstrate
various CUDA programming principles, and efficient CUDA
implementation of algorithms in specific application domains.

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

设置环境变量

export PATH=/usr/local/cuda-8.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64:$LD_LIBRARY_PATH

添加系统变量修改到系统文件
sudo vi /etc/profile

在最后添加上面两句,然后保存。使立即生效

sudo ldconfig //环境变量立即生效
