Open your System Settings. We need to make changes to Power and Brightness & Lock settings.

System Settings

Power Settings

Change the value of Suspend when inactive for to Don't suspend.

Power Settings

Brightness & Lock Settings

Change the value of Turn screen off when inactive for to Never.

Brightness & Lock Settings

This should help to achieve your desired result.

Thanks. For my particular issue (my speakers which were powered by the monitor would turn off when the screen gets locked) I just had to disable a setting of the display itself. Still, this answers the question I asked. – Andreas Hartmann Sep 25 '13 at 13:02

I had to install additional screensaver program XScreenSaver and use it instead of default one because accepted answer had no effect for me on Ubuntu 16.04 and 17.10.

Install XScreenSaver:
```
 sudo apt install xscreensaver
```
Add this command to Startup Applications:
```
 xscreensaver -nosplash
```
Disable default Super+L shortcut
- Install CompizConfig Settings Manager
```
sudo apt install compizconfig-settings-manager
```
- Launch it and click "Ubuntu Unity Plugin"
- Click the button next to "Key to lock the screen."
- Disable
Add this command to enable Super+L shortcut for XScreenSaver in System Settings → Keyboard → Shortcuts → Custom Shortcuts:
```
 xscreensaver-command -lock
```

How can I add Super (=Windows button / CMD) + L as a custom shortcut if pressing that makes me logout directly :) when I want to set the shortcut? /// found out myself. Go to Settings --> Keyboard Shortcuts --> roughly in the middle, you find the topic System, at the 3rd line, there is Log out with Super+L Shortcut. Click on it and give it something you do not need like Super+;. Then go down to Custom Shortcuts and add Super+L for the custom logout command. – questionto42 Feb 03 '22 at 09:12
