How do I stop the screen from fading out and powering off, on lock-screen?

Question

In the office, when I leave my computer, ie. to fetch some coffee, I press Super+L and activate the lock-screen.

This results in the screens fading to black, and subsequently turning off. While this is beneficial if I am gone for longer periods (thus it kicks in via timeout) it is tedious, to have to wait for the screens to power back up, when I am only away for a short period.

So, is it possible to disable the immediate screen power-off, when I do a lock - while still keeping the timeout power-off that comes when the computer is idle?

Solution

Depending on the flavor of screensaver you use, there are power settings for the screensaver. For me, I can configure screensaver settings via the settings menu. It has an advanced tab with power settings. Here is how it looks for me:

Well I guess the Ubuntu-equivalent is "All settings > Brightness & Lock > Turn screen off when inactive for: <time>" This was not, as the question states, what I was looking for. I like this.
