Ubuntu（desktop & server) 装机配置

如果卡在进入安装界面的地方，可以在u盘启动过程中，出现选择界面：try ubuntu 、install ubuntu等，此时点“e”键，会出现一个黑框，此时在倒数第二行左右，找到：

quiet splash - - - 改成 quiet splash acpi=off

1. 更换清华源 （附：删除失效PPA）

（Only removing /etc/apt/sources.list.d/nvidia-docker.list）

1 Backup the sorces file

cd /etc/apt/
sudo cp sources.list sources.list.bak

2 Change sorce (https://mirror.tuna.tsinghua.edu.cn/help/ubuntu/)

sudo vim sources.list
i
ctrl+shift+v
esp
wq

3 update sorces
sudo apt-get update
sudo apt-get upgrade

前处理

sudo gedit /etc/modprobe.d/blacklist.conf
add:blacklist nouveau
    options nouveau modeset=0
保存退出；
sudo update-initramfs -u # 此时可以用lsmod | grep nouveau #查看没有输出即下载成功
Ctrl+Alt+F1
sudo service lightdm stop  #关闭图形化界面，最后还要打开

2. 安装显卡驱动

0. System settings
uncheck the settings : Software&Update -> Ubuntu Software -> Proprietary drivers for devices(restricted)
1. check the Graphics device model
ubuntu-drivers devices ( i recommend this commend)
or
lspci |grep -i vga
lspci |grep -i nvidia

2. Install the driver
sudo ubuntu-drivers autoinstall (for recommended version)
sudo apt install nvidia-390  (for another version)

This work well, too:
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo apt install nvidia-390

3. reboot
sudo reboot

3. 后处理

就进入tty（ctrl + Alt +F3)，然后安装了lightdm:
sudo apt-get install lightdm，选择lightdm
退出，一切正常。

4. 卸载显卡驱动

sudo /usr/bin/nvidia-uninstall
sudo /usr/local/cuda-8.0/bin/uninstall_cuda_8.0.pl
sudo rm -rf /usr/local/cuda-8.0

sudo apt-get --purge remove nvidia*

sudo apt autoremove

To remove CUDA Toolkit:
$ sudo apt-get --purge remove "*cublas*" "cuda*"
To remove NVIDIA Drivers:
$ sudo apt-get --purge remove "*nvidia*"
