How to deactivate screensaver

Hi guys. I'm not going to describe my computer, because I'm sure it's not a hardware problem and there's a simple fix for this.

GOAL: Permanently disable screensaver so I can display my dashboards on the television.

Description of problem:

1. Screen goes blank until I wake it with a mouse. DOES NOT go to lock screen.

2. I've gone to Settings -> Power Management AND Settings -> Screensaver to disable everything that needs to be disabled.

3. After about 10 minutes, screen still goes blank. It is not a problem of the television. Worked fine on my other computer.

Please advise and thank you in advance.

This is a common one... I recall jumping through hoops to solve this on 12.4 core. On desktops, this is not so problematic, but on Notebooks, it is. This is because there is yet another setting for the Touchpad that has to be configured.
I am in the middle of an engine block at the moment. But I wanted to get a quick reply in to acknowledge that your question has been seen. Will try to get a more detailed reply in later if Swarfendor hasn't rescued it yet.

Hi,
I just happened to look at disabling background change and I came across this one here
https://askubuntu.com/questions/1048774/disabling-lock-screen-18-04

I would obviously skip everything UI ubuntu wise but the gsettings option is in fact the equivalent to Gnome Tweaks. So as a suggestion I would try GNOME Tweaks. Once installed and you set things as you like you can uninstall the UI. The settings remain (just did it on a 15.1 Education for keyboard layout change with Alt+Shift)

You can also take a look at this link https://askubuntu.com/questions/1034000/prevent-users-from-changing-the-desktop-background-on-ubuntu-18-04. The second answer is the way to go (with the appropriate key for screensaver) but is has a typo (and due to low reputation purists deleted my fix). It is not

Code:

systemd-db

but

Code:

system-db

Let us know if you had any progress... it is actually intriguing...

Concise, informative and very helpful
