Adding an accidently removed startup application

Question

I have accidentally removed "Cinnamon Settings Daemon - xrandr" from startup applications on my Linux Mint as I was trying to remove another application, but the topmost application was selected so this got removed.

How can I add it back, I think it may be an important startup app which I have accidentally removed

This is image with the setting present, but in my case this topmost option has been accidentally removed

Answer 1

The entry simply runs the command csd-xrandr:

So, to add it again, just click on the "+" icon on the bottom of the settings screen:

And then enter the following values for each of the fields (so that it looks like in the first screenshot):

Name: Cinnamon Settings Daemon - xrandr
Command: csd-xrandr
Comment: No description
Startup delay: 0

Then, click "save" and you should be fine.
