使用Ubuntu命令进行安装
根据需要进行
# 如果您想更改按键绑定（在某些 PC 上不起作用）
# DELL Vostro 3020 Small Desktop虽然有效但过后遗忘
$ setxkbmap -option ctrl:swapcaps
# 恢复到按键绑定
$ setxkbmap -option
# 如果您想更改按键绑定（在某些 PC 上不起作用）
# DELL Vostro 3020 Small Desktop有效
$ sudo vi /etc/default/keyboard
XKBOPTIONS="ctrl:swapcaps"
$ sudo systemctl restart console-setup
# Ubuntu重启
# 如果要添加用户并将其设置为可执行 sudo
$ sudo adduser masumi
$ sudo gpasswd -a masumi sudo
# 如果使用 ifconfig 显示当前网络配置
$ sudo apt -y install net-tools
# 如果要显示以太网链路速度
$ sudo apt -y install ethtool
# 如果要显示运行时钟。
$ sudo apt -y install cpufrequtils
全局配置Git
$ cd
$ git config --global credential.helper store
$ git config --global user.email "taro@nihon.co.jp" # 设置地址
$ git config --global user.name "Taro Nihon" # 设置姓名
因为时间延迟了8小时，所以需要进行调整。
将BIOS时钟调整为中国时间
Windows使用BIOS的中国时间
Ubuntu将BIOS时间设置为本地时间进行解释
$ sudo hwclock -D --systohc --localtime
EPSON Endeavor的以太网使用即为使用以太网功能。
