Recebi uma mensagem dizendo que fiquei sem espaço no disco rígido, por isso apaguei algumas coisas, jogos grandes que nunca joguei, etc., algumas horas depois, recebi a mesma mensagem, por isso apaguei mais algumas grandes coisas, e sem fazer nada, eu estava ficando rapidamente sem espaço HD. Finalmente, localizei o problema em um arquivo syslog de 16 gb e um arquivo syslog.1 de 11 gb. Abri e recebi esta mensagem repetitiva:

Alguma ideia de como resolver isso? FYI, embora eu tenha usado o Ubuntu por um tempo agora, eu ainda sou um noob, então, por favor, seja detalhado.
