I wanted to adjust the size of my desktop background image, but could not see any options in Settings -> background for doing so. I came here and found these two questions: problem with background image size and How do I easily resize a wallpaper for my screen?. Both feature an image of Settings -> appearance with a number of options, and I have a vague memory that I had something like that once, but it is nowhere to be found now. These questions are 7 and 4 years old as of this writing. I did find something called 'Appearance' in the Ubuntu Store. Did this functionality get moved into that app?
I am no master of gimp, but I also tried using it to reduce the size of my image, and frankly, I can't even tell if Ubuntu accepted my 'set as background' command, because it still looks the same size. Are there any other options here?
