It would be probably better if the machine never turned its screen off

It is the choice of the users: I think there is a twoline script to disable screenlock (look at the manual; I have not really tried it)

I personally use caffeine-ng, which gives you an easy way to enable/disable the screensaver/auto sleep. But it does not seem to available from the Ubuntu repos sadly.

This is the script responsible for setting the screenlock:

Which is documented here.

Hence, we can close this issue. If I have misunderstood something, feel free to reopen this issue.

Note that personally I think that it's not good disabling automatic screen saver by default -- if a user does not care, have a safer default (does not burn an image on the screen -- not even during testing).
