I have recently been trying to activate a screensaver on my computer so that when idle, my computer will have a screensaver. I have selected a screensaver, tried various ones in fact, and when the computer goes idle, nothing comes up, just a black screen. It seems that linux is not loading any of the screensavers, or they dont exist. Does anyone have a solution? Also, after getting the screensaver working, is there a way to make the computer lock when the screensaver activates; to my knowledge, you can lock it when it idles, but not when the screensaver is active. Thanks.
