The duplicate question was the same, how to resize the app icons. But the answers did not work for me. From my home setting on Terminal I pasted: /usr/share/gnome-shell/theme/ubuntu.css and got the response; bash: /usr/share/gnome-shell/theme/ubuntu.css: Permission denied I tried the other answer and pasted: /usr/share/gnome-shell/theme/gnome-shell.css and got the same response; bash: /usr/share/gnome-shell/theme/gnome-shell.css: Permission denied

  • run this cmnd for going back to default gsettings reset org.gnome.nautilus.icon-view thumbnail-size – PRATAP Dec 01 '19 at 03:38
  • but it will increase thumbnail-size in nautilus window also. – PRATAP Dec 01 '19 at 03:38
  • I tried the first command and 'your-size' was not recognized. So I took that out and received: Usage: gsettings [--schemadir SCHEMADIR] set SCHEMA[:PATH] KEY VALUE

    Set the value of KEY to VALUE

    Arguments: SCHEMADIR A directory to search for additional schemas SCHEMA The name of the schema PATH The path, for relocatable schemas KEY The key within the schema VALUE The value to set

  • replace your-size with 24 or 48 or 64 any value you prefer – PRATAP Dec 01 '19 at 04:26
  • Sorry but this did not help. I will explain. I do not need help resizing the icons for folders on the desktop nor in Nautilus. (The Ctrl + mouse scroll wheel was a good shortcut idea for that. Thanks.) At the bottom left corner of my dock is a button with nine dots arranged 3X3. It identifies itself with the mouse pointer as "show applications". When I click that button icons spray over the desktop arranged in 4 rows of 6 small icons which are the packages the I can choose from. Some I can identify (Amazon, LibreOffice, etc.) but the icons are so small. Can they be "thumbnail" size? – Paul SVD Dec 02 '19 at 01:15

  • As I commented above, the Ctrl + mouse scroll wheel was a good shortcut idea for resizing the folder icons on the desktop and in Nautilus. But that is not my problem. I want to increase the size of the app icons. I was directed to a duplicate question with 3 answers. I copied and pasted all of the command line variations in the answers and always get the response, "Permission denied" – Paul SVD Dec 03 '19 at 02:03

In nautilus, the minimum size of 48px is hard-coded within their software. The setting that control this is:

You can see by running this command it's already set to small, so it can't get smaller:

gsettings get org.gnome.nautilus.icon-view default-zoom-level

Now, depending on your preference, you can set the zoom level by altering the value within the quotes from the list of values listed below

gsettings set org.gnome.nautilus.icon-view default-zoom-level 'value'
  • small
  • standard
  • large
  • larger
  • largest

For fine grain control, use 

gsettings set org.gnome.nautilus.icon-view thumbnail-size 100

Replace 100 with your desired size
