ユーザーとしてログインできません

すべてがrootとして実行されます。 xを起動してiceWMに入ることができます。私はi3を使用する予定ですが、「other」としてログインし、「root」と書くとlightdmを介しても機能します。

TTYを使用してログインすることもできますが、rootとしてのみログインできます。ユーザーとしてログインしようとすると、しばらく停止して前の状態に戻ります。

TTYにrootとしてログインして操作を実行すると、そこにファイルはありません。ディレクトリがありますというメッセージがsu mats表示されます。su: failed to execute /usr/bin/fish: No such file or directory/usr/bin

#journalctl -fこれは通常のユーザーとしてlightdmを介してi3を開こうとした結果です。

nux-v80v:~ # journalctl -f
