一、网络篇
ip addr show
eth0接口的IP地址
直接显示IP
hostname -I
ifconfig（Ubuntu使用该命令需要配置）
hostname查询主机名称（window&ubuntu通用）
Ubuntu20.04截图快捷键（24版本按PS键即可）
CTRL+SHIFT+PS自由选区截图
PS全屏截图
二、Ubuntu远程联机一段时间后莫名奇妙断开
Ubuntu20.04禁用休眠配置
创建如下配置文件
sudo touch /etc/polkit-1/localauthority/90-mandatory.d/disable-hibernate.pkla
sudo vim /etc/polkit-1/localauthority/90-mandatory.d/disable-hibernate.pkla
添加如下配置
[Disable hibernate (upower)]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=no
ResultInactive=no
ResultAny=no
[Disable hibernate (logind)]
Identity=unix-user:*
Action=org.freedesktop.login1.hibernate
ResultActive=no
[Disable hibernate for all sessions (logind)]
Identity=unix-user:*
Action=org.freedesktop.login1.hibernate-multiple-sessions
ResultActive=no
禁用挂起配置
sudo touch /etc/polkit-1/localauthority/90-mandatory.d/disable-suspend.pkla
sudo vim /etc/polkit-1/localauthority/90-mandatory.d/disable-suspend.pkla
[Disable suspend (upower)]
Identity=unix-user:*
Action=org.freedesktop.upower.suspend
ResultActive=no
ResultInactive=no
ResultAny=no
[Disable suspend (logind)]
Identity=unix-user:*
Action=org.freedesktop.login1.suspend
ResultActive=no
[Disable suspend for all sessions (logind)]
Identity=unix-user:*
Action=org.freedesktop.login1.suspend-multiple-sessions
ResultActive=no
重启
sudo reboot
三、refresh界面频繁刷新
解决“刷新系统软件源需要认证” / “refresh the system repositories” 弹窗
创建文件 /etc/polkit-1/localauthority/50-local.d/46-allow-packagekit.pkla 并写入内容：（sudo vim）
sudo vim /etc/polkit-1/localauthority/50-local.d/46-allow-packagekit.pkla
[Allow Refresh Repository all Users]
Identity=unix-user:*
Action=org.freedesktop.packagekit.system-sources-refresh
ResultAny=no
ResultInactive=no
ResultActive=yes
四、Authentication is required to create a color profile
创建一个配置文件
sudo vim /etc/polkit-1/localauthority/50-local.d/45-allow-colord.pkla
添加并保存
[Allow Colord all Users]
Identity=unix-user:*
Action=org.freedesktop.color-manager.create-device;org.freedesktop.color-manager.create-profile;org.freedesktop.color-manager.delete-device;org.freedesktop.color-manager.delete-profile;org.freedesktop.color-manager.modify-device;org.freedesktop.color-manager.modify-profile
ResultAny=no
ResultInactive=no
ResultActive=yes
按键:wq退出
