Cómo reiniciar una sesión de Fedora Gnome bloqueada

A veces, mi escritorio Fedora se congela, se me bloquea. El PC sigue conectado en la red, puedo hacer ping desde otro ordenador.

Si puedes hacer ssh a tu Fedora congelado, aquí están los comandos que estoy haciendo para arreglar mi computadora.

Comprueba la versión de Linux

Comprueba qué sesión de escritorio estás ejecutando (DESKTOP_SESSION es obsoleto) :

[moore@mux ~]$ echo $XDG_CURRENT_DESKTOP 
GNOME

[moore@mux ~]$ echo $DESKTOP_SESSION
gnome

[moore@mux ~]$ echo $XDG_SESSION_DESKTOP 
gnome

Comprueba la versión de Linux que estás ejecutando, yo estoy ejecutando una Fedora 33 Silverblue:

[moore@mux ~]$ cat /etc/os-release 
NAME=Fedora
