How to Re-size Desktop Icons?

I tried re-sizing the desktop icons to a smaller footprint, though it did not work. I even rebooted the system. I went into configure menu and then Icons and then Icon Theme / Advanced
and selected a smaller size for desktop icons from the small drop-down. Saved and backed out only to notice no change. How can I successfully re-size the desktop icons?

Running 42.1 Leap KDE

In the image, is it similar to where you navigated?

System settings> appearance> Icons> Advanced…

I’m sorry… I don’t understand what you mean.

That’s where I went if that’s what you mean…

I changed the size in the drop down to 16 and still no change in the desktop icons.

What “desktop icons” are you talking about exactly?

If it’s about the icons in the folderview applet (that shows the contents of your ~/Desktop folder), just right-click on an empty space in the applet and choose “Folderview Settings”.
You should be able to change the size of the icons there (under “Icons”).

I don’t like folder view and immediately change it to desktop view.
So the folders are now on the main desktop.

Also, I see NO settings to remove the Trash folder from desktop
like Mint offers. Actually Mint has a several more options in their
control panel than OpenSuse has.

This is still a folderview applet, only in “containment mode”.

So, right-click on an empty space on your desktop and choose “Folder Settings” (or click on the toolbox icon in the upper-left corner, it’s reachable there too).

Also, I see NO settings to remove the Trash folder from desktop
like Mint offers.

The trash folder on your desktop is just a “link”.
Remove ~/Desktop/trash.desktop and it will disappear.

Actually Mint has a several more options in their
control panel than OpenSuse has.

I doubt that.

Unless it uses a different desktop environment, that would have completely different options and features of course.

It’s KDE and it\s true.

And what KDE? (what version)

We don’t strip anything out.
If they use the same version, it should have the same options.
Though the set of packages that are installed by default may differ of course.

It also would help if you’d tell in more details what “several more” options are in Mint that are missing in openSUSE… (and where, i.e. what exactly is this “Control Panel” you are talking about)
