Nuevamente, soy nuevo en esto, por lo que es posible que no entienda qué es relevante. Avíseme si puedo publicar más información.

debug1: No xauth program.
Eso parece un problema. Asegúrese de tener el xauthprograma instalado tanto en el servidor como en el cliente. Estás iniciando sesión como root, así que asegúrate de que xauthtambién esté en la RUTA del root. No estoy completamente seguro de que este sea el problema, porque en mis pruebas encontré otros mensajes de error ("La solicitud de reenvío X11 falló en el canal 0", que aparece incluso sin -v) si el reenvío X11 no funcionaba debido a la falta de xauth, pero esto puede deberse a una diferencia de versión o configuración.
En el strace xclockresultado, identificó una línea que no coincide entre una máquina en funcionamiento y una máquina que no funciona. En la máquina que no funciona:
open("/lib64/tls/x86_64/libnss_files,dns.so.2", O_RDONLY) = -1 ENOENT (No such file or directory)
Ese nombre de archivo es incorrecto: libnss_files,dns.so.2se supone que no existe, lo que existe es libnss_files.so.2y libnss_dns.so.2. Estos archivos son utilizados porNSS, el componente de la biblioteca C estándar que administra fuentes para nombres de hosts, usuarios, etc. Las fuentes típicas incluyen files( /etc/hosts, /etc/passwd, ...),dns,ldap, etc. Tiene una fuente llamada files,dnsen lugar de una fuente llamada filesy una fuente llamada dns. Edite el archivo /etc/nsswitch.confy cambie las líneas SOMETHING: files,dnsa SOMETHING: files dns, es decir, las palabras deben estar separadas por espacios en blanco, no por comas.
No entiendo completamente el rastro, pero definitivamente es incorrecto y podría estar causando el problema. En particular, creo que una hosts: …línea incorrecta /etc/nsswitch.confpodría provocar que su sistema no encuentre el archivo localhost.
