双系统卸载和安装-及ubuntu配置

一、双系统安装卸载的方法

1 安装win10，制作usio软碟通镜像到u盘，uefi启动。

2 为新系统预留黑色未新建格式的分区200G（/ext4和/homeext4各100G）

3 安装ubutnu也是软碟通，ufei启动。安装在/和/home的新建分区下

4 卸载ubutnu，进入diskpart的partition的efi对其letter=p，进入p后rd -r ubuntu。之后再删除ubuntu分区

5 挂在硬盘，格式化为ext4，但是不会吃掉存贮

格式化为ext4，但是不会吃掉太多存储量

sudo umount /dev/sdb
sudo mkfs.ext4 -m 0.05 /dev/sdb
sudo mount /dev/sdb /mnt/nextcloud

二 、ubuntu系统安装好后优化系统查看系统uname -a

0 图标最小化

gsettings set org.gnome.shell.extensions.dash-to-dock click-action 'minimize'

1 首先更改源，更新系统，才能成功安装teamviewer

2 安装gnome-tweaks，添加startup：teamveiwer，更改字体、图标大小

3 ssh-server sudo apt-get install openssh-server

查询 service ssh status,后是active就可以连接了

4 高效开发工具：git、vim、pdb(python调试器）、Terminator（分屏）、screen任务托管、docker

5 docker安装

1 setup docker repository

$ sudo apt-get update

$ sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    software-properties-common

https://docs.docker.com/engine/install/ubuntu/

2 Add Docker’s official GPG key:

 $ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

3 x86-64/amd64，添加源库

sudo add-apt-repository
“deb [arch=amd64] https://download.docker.com/linux/ubuntu
$(lsb_release -cs)
stable”

4 安装dockers

$ sudo apt-get update
$ sudo apt-get install docker-ce docker-ce-cli containerd.io

5 验证sudo docker run hello-world

6 docker login，search zhangjianhehenry

7 运行nextcloud

docker run -d --name nextcloud --restart=always -p 30:80  -v /mnt/nextcloud/data:/var/www/html/data zhangjianhehenry/nextcloud
#更改trust域名
docker exec -it nextcloud /bin/bash
# 3天自动删除
‘trashbin_retention_obligation’ => ‘auto,3’,

8 添加data盘自启动

sudo blkid #复制uuid
sudo vim /etc/fstab  #粘贴uuid
UUID=d2c70c37-de0d-48fe-9fcc-8600f6ece7d0 /mnt/nextcloud ext4 defaults 0 0

三 NVIDIA安装，无显示器远程桌面

安装结束后要重启

sudo apt-get install  xserver-xorg-core-hwe-18.04
sudo apt-get install  xserver-xorg-video-dummy-hwe-18.04  --fix-missing
sudo vim /usr/share/X11/xorg.conf.d/xorg.conf
Section "Device"
    Identifier  "Configured Video Device"
    Driver      "dummy"
EndSection
Section "Monitor"
    Identifier  "Configured Monitor"
    HorizSync 31.5-48.5
    VertRefresh 50-70
EndSection
Section "Screen"
    Identifier  "Default Screen"
    Monitor     "Configured Monitor"
    Device      "Configured Video Device"
    DefaultDepth 24
    SubSection "Display"
    Depth 24
    Modes "1920x1080"
    EndSubSection
EndSection

调整分辨率

gnome-tweaks font都设置为10，size=0.7

9 pycharm，miniconda

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --set show_channel_urls yes

pip源更换
mkdir ~/.pip
vim pip.config

10 cuda，cudnn,opencv,torch

pip install opencv-python opencv-contrib-python
pip install torch==1.5.0+cu101 torchvision==0.6.0+cu101 -f https://download.pytorch.org/whl/torch_stable.html

11 添加绘图中文
