在新版本24.04时，除了以往的远程桌面功能， 新增远程登录 remote login。
远程登录可以不再依赖虚拟HDMI，或保持在桌面状态。
远程登录在锁屏状态也能连接。
假如远程桌面用的是3389端口， 那么这埋在远程登录我们使用3390
在安卓或IOS手机和macos端，我们可以下载Window App客户端来远程这台ubuntu，
但macos和win11等新系统连接后却是黑屏，而win7等旧系统却可以成功连接你的ubuntu，
解决办法:
你可以这样做，导出为rdp文件或创建一个test.rdp新文件，用文本编辑器修改:
找到显示以下内容的行：
use redirection server name:i:0
将其更改为：
use redirection server name:i:1
拖回去即可也可以复制下边现成的:
