Ubuntu – How to disable screensaver in Xubuntu 18.04

How do you disable the screensaver/powersave function in Ubuntu 18.04?

In Ubuntu 16, you disabled the screensaver in two steps:

First, opening the screensaver gui and selecting "none". But this alone didn't stop the monitor from blanking.
The X server had its own powersave feature that would turn off monitor output when nothing on the screen changed. To disable that, you had to run xset s off.

In Xubuntu 18.04, the second part no longer works. Even though I've run xset s off, my monitor output still blanks if nothing changes after a few minutes. How do I fix that?

I'm running the XFCE desktop, with the xubuntu-desktop package, if that matters.

Since you're running Xfce, you could try changing the settings of the Xfce Power Manager.

Find Power Manager in the Applications menu or run xfce4-power-manager -c from the terminal. Then you can change the settings in the Display tab.

If Display Power Management is turned ON, then the Power Manager should be in control instead of X11. You should then be able to prevent blank/sleep/power off by setting the appropriate sliders to Never.

OK I believe the exposed arguments are related to whether or not windows and there contents are displayed behind the screen saver (this will be relevant to certain screen savers that draw on the screen and the like). So it is in short if your desktop is exposed or not. This is a educated guess, the terminology used is strange I think.

I do how ever understand this xset s N N as you referenced it, works as follows,

xset s 60 10

Will set the screen saver to come on after 60 seconds of in activity as represented by the variable 60, and the 10 will force the background image (your desktop if you use xset s expose) to change every 10 (mins or seconds). This is refrenced as s [Length[Period]] in the manual (length of inactivity and period between refreshing)

Some other interesting commands were s blank / s noblank These are responsible for if you want the screen to fade to black instead of a screensaver.

xset s blank

preinstalled To enable this or

xset s default

To set factory defaults

For you if you want it as off as you can do this, one at a time

sudo -i

xset default

xset s noexpose

xset s noblank

xset s off

I just realized lock and suspend are two different things in Ubuntu 18.04.

One may disable the lock here:
