I want my screen to turn off after being inactive for 60 minutes, but the longest time I can do that for is 15 (by default.) So can I edit settings to change this value to 60 so it turns off after 60 minutes? I don't want to choose "Never" bc then it could burn into my screen if I accidentally leave it open for 8+ hours, nor do I want to download/use an application to accompish this. Anyone have an idea of how I could do this?

  • Yes, this also answered it, Thank you.

You can forcibly set the screen blank setting to 1 hour with the following command:

gsettings set org.gnome.desktop.session idle-delay 3600

This causes a "1 hour" item to show up in the dropdown, but the dropdown will be glitched to always say "Never". It should theoretically still work though.
