xscreensaver have some issues that I can't fix so far :
- can't change the default behavior pour Lubuntu only (to set to blank
mode)
- can't stop it when playing videos

I'm also not really happy with it, it's one of the 1st thing I change on
a Lubuntu system.

To be able to remove, we need to identify the use cases, and see how we
can handle them.

For the locking screen, xtrlock doesn't seems to be appropriate, because
you need to hide the screen when you lock it (it's a security problem).
But there is also xlock (in xlockmore package) which could work.

For the screen saving, It's relative to CRT screen, which are still
used. But, having the ability to switch to a blank image maybe is
enough. And I don't think xlock can do it.

If there are other use cases, let me know :)
