あるFedoraノートブックから別のノートブックに簡単なgeditウィンドウを渡したいです。 geditコマンドは、「クライアント」ラップトップから渡されたX11ウィンドウではなく、「サーバー」ラップトップでgeditウィンドウを開きます。
注：geditクライアントでsshコマンドを実行したときにサーバー上で実行されているインスタンスはありません（コマンドはサーバーにインスタンスを残したため、再試行する前に別のSSH接続から直接インスタンスをシャットダウンしました）。
仕える人/etc/ssh/sshd_config
X11Forwarding yes
X11DisplayOffset 10
顧客.ssh/config
ForwardX11 yes
ForwardX11Trusted yes
テストコマンドの表示：
> ssh -X me@server 'echo $DISPLAY'
localhost:10.0
クライアントコマンド：
ssh -vvv -X me@server "/usr/bin/gedit"
コマンド出力
