wow, that answer was rude
The info which we need is:
[*] what version of mint do you use? daryna?
[*] With gnome or kde?
[*] What screensaver? is it included in mint or did you download? if so, from where did you download it?
Please provide these answers so we can help you.
Just a note: The better and more detailed a question is, the greater is the possibility that someone might be able to help.
