On my netbook with Bodhi 4.2.0 32-bit, there's the Fiberlamp screensaver, which is running after the netbook is idle for a while.
Then after some more time has passed, the screen gets black.
Sometimes, when the screen is black, I noticed some orange text, mentioning something about Crackberg and below this the folders of my personal folders are listed.
This is visible for only a few seconds (so it's almost impossible to take a picture of it) and then the screen gets black again.
Then wehn I touch the touchpad I'm asked for my password to unlock the screensaver and everything is as usual.
Have you ever heard about Crackberg?
What is it all about?
EDIT: Looks like it's a developer of a group of screensavers, isn't it?
I really was worried about this, because according to the name it might have been some sort of cracking having happened.
