I would like to have my screen fully powered at all times, but it goes to standby once I lock my PC.
Open your System Settings. We need to make changes to Power and Brightness & Lock settings.
Change the value of Suspend when inactive for to Don't suspend.
Brightness & Lock Settings
Change the value of Turn screen off when inactive for to Never.
This should help to achieve your desired result.
2Thanks. 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. Sep 25, 2013 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.
sudo apt install xscreensaver
Add this command to Startup Applications:
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."
Add this command to enable Super+L shortcut for XScreenSaver in System Settings → Keyboard → Shortcuts → Custom Shortcuts:
How can I add
Las 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
LShortcut. Click on it and give it something you do not need like
;. Then go down to
Custom Shortcutsand add
Lfor the custom logout command. Feb 3, 2022 at 9:12
