Fedora 19-起動時にログイン画面が表示されない

Question

システムでいくつかの一般的な更新を実行しましたが、以下の問題が発生しました。

通常どおりサービスをロードして起動しますが、ログイン画面（私はKDEを使用）を起動しようとすると、停止してもう一度サービス開始画面が表示され、しばらくするとブロックされます。

別のttyに移動し、rootとしてログインして、次のコマンドを実行できます。

init 3 init 5

そして、それは期待通りに始まります。しかし、再起動するたびに、デスクトップを表示するために同じことをしなければなりません。

私は/var/log/boot.logファイルと私は珍しいものを見ていません。そこにあるよ：

問題を解決するにはどうすればよいですか？

編集： GDMで問題なく開始できます。問題はKDMにあるはずです。

おそらくSELinuxが起動を妨げています。鉱山も始まらなかった。そして、これが私の問題を解決するために私がしたことです：

2つのオプション（レスキューモード）を選択し、eを押します。
..... rhb quietの前に3を追加（これのように：rhb quiet ""）を押して Ctrl+x
次に、仮想端末にrootとしてログインし、startxと入力して押しました。 Enter
次に、グラフィカルにログインしました
SELinuxで無効にしました。このOpenターミナルのように、次のように入力します。
```
vi /etc/selinux/conf and press enter; 
```
SELINUX = enforcingの行をSELINUX = disabledに編集します。
通常どおり再起動し、問題を解決しました

Fedora 20での同様の問題に対する私の解決策は、デフォルトのターゲットレベルをデフォルトの「グラフィカル」から「マルチユーザー」にリダイレクトすることでした。

これは、以前のSysV起動シーケンスの同じinitdefault 5および3に似ています。

システムにアクセスできなかったため（コンソールとSSHの両方で完全なサービス拒否が発生しましたが、ポート22はスキャンに対して開いていると報告されていました）、ライブCD（AntiX Linuxを使用）からシステムを起動し、そこから変わります。

 root @ antiX1：〜＃cd /mnt root@antiX1:/mnt# mkdir root root @ antiX1：/ mnt＃mount/dev/mapper/vg_lv_root/mnt /ルート

（上記のディスクIDは特定の環境で変わる可能性があります。私はLVMを使用しています）

 root @ antiX1：/ mnt/root＃ln -sf /mnt/root/lib/systemd/system/multi-user.target /mnt/root/etc/systemd/system/default.target root @ antiX1：/ mnt/root＃cd /mnt/root/etc/system root@antiX1:/mnt/root/etc/systemd/system# ls -l default.target lrwxrwxrwx 1ルートルート46 Jun 3 17:32 default.target-> /mnt/root/lib/systemd/system/multi-user.target

これを実行した後、システムは正常に起動し、通常のグラフィカルデスクトップに到達しました（私にはわかりません-GUIではなくテキストログインプロンプトに到達するためのものでした）。

しかし、この方法で2つの故障したシステムを本番環境に戻すことができました。
