Frequently Asked Questions
Why doesn't my screensaver activate automatically?
Possibility A
The screensaver daemon is not currently running. You can check this by looking at the running processes, or just run xfce4-screensaver to start it up.
Possibility B
Another application has disabled the X11 screensaver. This can be determined by running xdg-screensaver status. If this command outputs “disabled”, try running the following commands to enable the screensaver.
xset s blank # Sets the X11 screensaver mode to "blank" xset s 300 # Sets the X11 screensaver timeout to 5 minutes
