Após algumas atualizações no Debian Sid, comecei a receber a seguinte mensagem no terminal quando executava o screenFetch:

_{[[ ! ]] ** (gnome-session-check-accelerated:21666): WARNING **:
Couldn't register with accessibility bus: Did not receive a reply.
Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.}

No entanto, tudo funcionava bem.

Dei uma busca no Google para resolver o problema e encontrei a solução.

Basta executar:


Pronto.
