I want some steps to add my own photos on the Gnome Screensaver. I tried to find out some tools for that but could not get the same which actually works to the point. What I found that screen saver and power management in Linux play hand in hand. While the screen saver is activated after a shorter time and then the power power management do not function so properly. This takes over the command and then switch off screens, specifically in order to save energy in notebooks and thus to increase the battery life. What are the other more things I can try out on my system.
