Ubuntu, lock screen but do not screensave

Question

When I do not use my graphical session anymore, the screensaver automatically lock it and power off the screen to save energy.

I want it to keep locking my session but not to power off the screen, is it possible ?

I use Ubuntu 18.04 with default gnome display manager.

Thank you,

Matias

As described in this thread on ubuntu forums it looks like this is part of the gnome-screensaver-command and there is no easy way to disable it. Try replacing the default screensaver with another one, like xscreensaver.

Hint: when you manually lock your screen, just hold the buttons a second longer and the screen won't turn off.
