Hey all!
I have recently had to switch my mom to using Linux due to a corrupt Windows 8.1 install on her Dell Inspiron 3647 desktop which was causing different issues at the time. [Given that she is behind the times & not very tech-savvy, that’s where I come in- I have to do all the tech-related tasks/duties around our household which I honestly don’t mind. 
Thankfully, switching her to a more lightweight OS like Zorin OS 16, the experience overall has been pretty good & it’s already taught be a TON about learning Linux.]
Anyway, I was following a guide/tutorial on Youtube in an attempt to try & resize her desktop icons to something a little smaller. This is the link in case anyone’s interested: https://www.youtube.com/watch?v=mVCfHsaRh7A The guide/tutorial shows the creator of this video using dconf Editor. I managed to get it installed & I navigated to the appropriate path [ Dconf Editor > Org > Gnome > Nautilus > Icon-View] but I’m not seeing the option labeled as “thumbnail-size” in dconf Editor at the path specified. I’m not sure on this as I am FAR from an expert on Linux, but do I have to add this option in somehow or is there another way to fix this? 
[Honestly, even after trying to look it up online, I did not see any similar posts asking what I am right now! No offense to the Linux community as a whole, but I find that a little unexpectedly ironic…]
So if there’s something else I am supposed to do or if anyone wishes to guide/instruct me, I would be very grateful! If any of you need more details or have to ask me anything, feel free to do so & I’ll get back with you!
Thanks in advance to anyone whom can help.
Nice to see ya again.
