我只是想将一个简单的 gedit 窗口从一台 Fedora 笔记本电脑转发到另一台。 gedit 命令在“服务器”笔记本电脑上打开 gedit 窗口，而不是在“客户端”笔记本电脑上打开转发的 X11 窗口。
注意：gedit当从客户端执行 ssh 命令时，服务器上没有运行任何实例（该命令确实在服务器上留下了一个实例，因此我在重试之前直接从另一个 ssh 连接终止它）。
服务器/etc/ssh/sshd_config
X11Forwarding yes
X11DisplayOffset 10
客户.ssh/config
ForwardX11 yes
ForwardX11Trusted yes
显示测试命令：
> ssh -X me@server 'echo $DISPLAY'
localhost:10.0
客户端命令：
ssh -vvv -X me@server "/usr/bin/gedit"
命令输出
OpenSSH_8.3p1, OpenSSL 1.1.1i FIPS 8 Dec 2020
