关于如何实现Windows于Linux之间的相互的远程桌面控制，我会在近期出分享，本文着重描述，XRDP在Ubuntu上面临的两个问题：

连接黑屏
别扭的桌面

注意，Ubuntu的版本是20.04.

连接黑屏问题

这个问题，主要是当你的本机没有注销的话，远程桌面就会黑屏，最佳解决策略就是退出本地登录，也就是注销登录，这个方法一定没问题。与windows那种完美的远程控制不同，在ubuntu中，本地登录和远程登陆是隔离开的，远程登录了不注销，那么本地就会黑屏，反过来本地登陆了不注销，远程就会黑屏。所谓注销就是logout，应该都懂，就是和关机、重启放在一起的那个选项。

或者使用网上的一些解决方案，但是这个放在在Ubuntu 22中会导致闪退。即，编辑 /etc/xrdp/startwm.sh 文件：

1. 打开文件

sudo vim /etc/xrdp/startwm.sh

2. 添加配置

unset DBUS_SESSION_BUS_ADDRESS

unset XDG_RUNTIME_DIR

3. 重启xrdp服务

sudo systemctl restart xrdp.service

桌面优化

注意，一定要先修改上面配置文件，再远程连接，否则会黑屏，这个时候需要重启。

反正记住一句话，重启后不在本地登录，那么远程必不黑屏！

如果不做任何配置，启动之后的桌面是非常别扭的，因为是Gnome的原始桌面，没有左侧的任务栏，窗口也没有最小化按钮，等等一些列问题。解决方案也很简单：

1. 添加配置文件

vim ~/.xsessionrc

添加：

export GNOME_SHELL_SESSION_MODE=ubuntu

export XDG_CURRENT_DESKTOP=ubuntu:GNOME

export XDG_CONFIG_DIRS=/etc/xdg/xdg-ubuntu:/etc/xdg

2. 重启xrdp服务

sudo systemctl restart xrdp.service

此时再连接，你将得到与原生桌面完全一样的效果！
