Hi Daniel,
Solved but not quite solved.
After I made some updates that appeared after I modified the file as you said, after restarted the system, the file was re-written without the modification and I was forced to insert the parameter again.
Will be an update to fix this issue?
Moreover, in Dashboard, at Core version, is written 7.0.3 (available).
If I check from Software Management, the messages said that no updates are available.
If I check from CLI, same messages.
:~$ sudo apt-get update
