Cierre de sesión aleatorio y repentino de mi sesión de usuario

Tengo un problema con ubuntu 14.10 y 15.04. Me desconecté de mi sesión de usuario al azar y de repente.

Aquí hay información de registro:

¿Alguna idea para arreglarlo?

Escriba Ctrl-Alt-F1 e inicie sesión en una sesión de terminal. sudo grep metacity /var/spool/log/*

@Aliot Cualquier error en los registros de Xorg también podría ayudar a solucionar el problema. sudo grep EE /var/log/Xorg.0.log

— carga

intentaste dpkg-reconfigure metacity? (nunca lo hice mysef, pero si falla, quizás el problema sea la metaciudad o la configuración del servidor X)

Esto es exactamente lo que mi amigo enfrentó. y se da cuenta de que su sesión siempre se desconecta repentinamente si ejecuta Chrome. ¿Experimentó esto mientras ejecutaba un programa específico? Esto es de hecho un error. en tu caso parece 'metaciudad'. intente usar otro programa de administrador de Windows.

¿Podemos tener información específica del hardware? Abra un terminal y escriba lspci y luego publique la salida, por favor. ¿También ha instalado algún tema o modificado la GUI?

Esto no está resuelto, pero es un error relativamente raro, si está utilizando la sesión gnome-flashback. En parte porque, en su mayoría, todos usan la IU predeterminada. Vea más detalles y suscríbase para ver si el problema se resuelve aquí: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1455916

Solución temporal: no use la sesión gnome-flashback.
