简单归纳了Xrdp远程连接可能会出现的问题

---

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）

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
