Actualización: el problema parece estar en el kernel 5.3.0-24, mientras se inicia en 23 funciona bien.
Desde hoy mi sistema Kubuntu 19.10 se cuelga cuando intenta conectarse a wifi. En el momento del arranque muestra este error:
iwlwifi 0000:03:00.0: Direct firmware load for iwl-dbg-cfg.ini failed with error -2
y luego dice
loaded firmware version 29.62a39462.0 op_mode iwlmvm
El controlador Intel se actualizó hace dos días y después de este error, cuando intenté abrir el administrador de controladores, no funciona; simplemente se queda ahí diciendo que recopila información sobre su sistema.
Intenté quitar el módulo y cargarlo nuevamente, no funciona. No pude encontrar nada en la web para ver cómo puedo instalar o reparar esto.

Habilité el inicio de sesión sin contraseña y deshabilité la conexión automática a wifi y el subprograma de red solía mostrar las redes disponibles incluso, cuando hago clic en conectar a cualquiera de ellas y doy la contraseña de kwallet, el sistema se bloquea inmediatamente y tuve que apagado con el interruptor de encendido.

Tengo el mismo problema. Mi solución hasta ahora es volver a la versión 5.3.0-23-generic del Kernel. Ahora funciona como se esperaba.
