Screensaver im mavericks doesn't work

Question

Hello,
I have the following problem:
My sreensavers doesn't work after 2, 5, 10 oder 20min. It doesn't matter which screensaver I choose.
Now, I want to control the plist-files but I'am not sure how much files I should have in my directories!
I've found plist files in
library/preferences/
home-library/preferences
home-library/preferences/byhost.
How much and which files should I have in these directories?
Thx for help!
Alex

Triple-click anywhere in the line below on this page to select it:
pmset -g assertions | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. The title of the window doesn't matter, and you don't need to post that.
