Fix for random screensaver (Macbook pro mid 2010)

I have found out a way to fix the random starting screensaver which I think is a really anoying problem for those who has a macbook pro from mid 2010 and has updated to Lion.

First open a Finder-window and gå to: "Macintosh HD"->"Library"->"Preferences" and delete "com.apple.screensaver.plist" and "com.apple.screensaver.plist.lockfile". You have to type your password for that. And remember to delete them from the Trash Can afterwards.

Next wait a few minutes and then go to your name in the right upper corner, next to the Spotlight and choose "Login window" I think its called. Then you login and the problem should be fixed.

The only thing is that you have to do it everytime you restart your mac.

It you have Skype installed and open you can see that it changes from "out" to "online"
