Actividad de disco excesiva de Ubuntu 16.04

Recientemente actualicé mi computadora portátil de Ubuntu 14.04 a 16.04. Principalmente debido a que la Canela se vuelve inestable. Hice una installation limpia de Ubunutu 16.04 con canela. Me he dado count de que mi disco SSD está constantemente "ocupado",

sudo iotop 

Puedo ver que cinnamon --replace is running constantly
