修正简体中文显示为异体(日文)字形

ubuntu/linux对中文支持的不太好, 在选择汉字字体时, 优先选择的是日文或者韩文, 需要手动调整优先级后重启操作系统解决

root权限编辑 /etc/fonts/conf.avail/64-language-selector-prefer.conf 配置文件

换`apt`源

apt update -y

使用`X11`替换`Wayland`

Wayland目前在我的AMD 5700U小机器上还是不太好用, 鼠标指针会有卡顿

编辑 /etc/gdm3/custom.conf

- #WaylandEnable=false
+ WaylandEnable=false

合上盖子不暂停系统(笔记本)

Make Ubuntu Not Go in Suspend When Laptop Lid is Closed

如果是在笔记本上安装的, 那么这个设置可以防止合上盖子Lid后Suspend系统

编辑/etc/systemd/logind.conf文件

- #HandleLidSwitch=suspend
+ HandleLidSwitch=ignore
- #HandleLidSwitchExternalPower=suspend
+ HandleLidSwitchExternalPower=ignore
- #HandleLidSwitchDocked=ignore
+ HandleLidSwitchDocked=ignore

然后重启 systemd-logind 生效

systemctl restart systemd-logind

安装 oh my zsh

sudo apt install zsh curl -y
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

ohmyz.sh

安装 golang

下载并解压到 /usr/local/go目录下

sudo apt install wget -y
wget https://go.dev/dl/go1.21.1.linux-amd64.tar.gz
sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go1.21.1.linux-amd64.tar.gz

修改所有user和所有shell的PATH环境变量，下面文件都添加一行 export PATH=$PATH:/usr/local/go/bin

/etc/zsh/zshenv
/etc/profile
/etc/bash.bashrc

新开一个shell会话验证

➜  ~ go version
go version go1.21.1 linux/amd64

Download and install

安装 hugo

sudo apt install build-essential -y
CGO_ENABLED=1 go install -tags extended github.com/gohugoio/hugo@latest

设置当前用户zsh的PATH环境变量

vim ~/.zshrc

+ export PATH=${PATH}:`go env GOPATH`/bin

新开一个zsh shell会话验证

➜  ~ hugo version
hugo v0.118.2+extended linux/amd64 BuildDate=unknown

安装 openssh-server

sudo apt install openssh-server

sudo vim /etc/ssh/sshd_config

- #PermitRootLogin prohibit-password
+ PermitRootLogin yes

sudo systemctl restart ssh

安装 gnome 插件

需要先安装有GNOME Shell extension

sudo apt install gnome-shell-extension-manager

划词翻译插件(可选辞典web地址,我选择的bing) Screen work translate
在 top bar 上显示当前网络上下行速度和总流量 Net speed Simplified
允许连接锁着的远程桌面Allow Locked Remote Desktop
- 默认情况下不允许连接已经锁屏的终端tty0 askubuntu

所有网卡都禁用ipv6

修改`/etc/sysctl.conf`

+ net.ipv6.conf.all.disable_ipv6 = 1

然后执行sysctl -p加载新的配置生效

修改`/etc/default/grub`

- GRUB_CMDLINE_LINUX="..."
+ GRUB_CMDLINE_LINUX="... ipv6.disable=1"

然后执行update-grub更新GRUB, 这种指定传递给内核命令行的参数的方式需要重启系统之后才能生效

安装`VLC`媒体播放器

https://www.videolan.org/vlc/download-ubuntu.html

sudo apt install vlc

快捷键

快捷键	功能
`v`	切换字幕

安装 `docker`

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

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh ./get-docker.sh

安装`virt-manager`

sudo apt install virt-manager -y

设置所有`sudo`组下的用户执行`sudo`命令不需要密码

EDITOR=vim visudo

# Allow members of group sudo to execute any command
- %sudo   ALL=(ALL:ALL) ALL
+ %sudo   ALL=(ALL:ALL) NOPASSWD:ALL

删除用户密码

危险操作, 具有sudo权限的普通用户就更是危险操作了, 不过自己在家用时, 每次解锁或登录不用输入一长串密码真的很方便!!!, 这样就可以把Screen Blank的时间调短一点了😄

passwd有一个-d参数

# passwd -h | grep -e "-d"
  -d, --delete                  delete the password for the named account

删除某个账户的密码

sudo passwd -d {username}
