X11の転送に失敗しました：ネットワークエラー：接続が拒否されました
OSがCentOS6.3のVPSがあります。 PuTTYとXming経由でstartxを実行したい。
ただし、次のエラーが生成されます。

上記のエラーの原因は何ですか？

@lilydjwgの回答によると、「Xディスプレイの場所」を埋めて、もう一度やり直しましたが、まだ間違っています。

PuTTYは、Xサーバーがどこにあるかを特定できません。 （LinuxのsshはXの下で実行されるため、この問題はありません。そのため、それを使用するだけです。）Xmingサーバーのアドレスで「X display location」の後に空白のボックスを入力します。
または、 MobaXterm を試してください。 Xサーバーが組み込まれています。
他の答えは時代遅れであるか、不完全であるか、単に機能しません。
また、GUIdプログラムの起動を処理するには、ホストマシンでX-11サーバーを指定する必要があります。クライアントがWindowsマシンの場合、Xmingをインストールします。クライアントがLinuxマシンの場合、XQuartzをインストールします。
次に、これがLinuxに接続するWindowsであるとします。 PuTTY上でX11プログラムを起動できるようにするには、次の手順を実行します。
- Launch XMing on Windows client
- Launch PuTTY
* Fill in basic options as you know in session category
* Connection -> SSH -> X11
-> Enable X11 forwarding
-> X display location = :0.0
-> MIT-Magic-Cookie-1
-> X authority file for local display = point to the Xming.exe executable
もちろん、sshサーバーは「他のユーザーにデスクトップの表示を許可する」デスクトップ共有を許可しているはずです。
MobaXtermおよびその他の完全なリモートデスクトッププログラムも機能します。
D-Busエラーはdbus-launchで修正できます：
dbus-launch command
Rootユーザーとしてログインせずに、Sudo権限を持つ別のユーザーを試してください。
