I have added a new entry at the bottom of the file, instead of overwriting any options, and everything is working correctly. However I'd like to customize this a bit further:
- How can I prevent the laptop from going to sleep when I close the lid? Basically I want to explicitly put it to sleep with a command, either in form of a GUI or keyboard shortcut. Which leads me to the next two questions...
-
a) How can I add a sleep/suspend button on the main menu, where the Log Out, Lock ... buttons are?
-
b) How can I add a keyboard shortcut to put it to sleep? If the previous option is not possible I'd be ok with at least having this, similar to how you can lock your machine with Super + L.
