I would like to delete some images with nautilus.

I increased the size to 200%.

My monitor has a high resolution and the image are too small for me.

I would like to increase the size even more, but it seems to be impossible.

See screenshot.

Is there a particular reason why increasing beyond 200% is not possible?

  • It can go up to 267%. Would that be enough, or are you looking for even larger?

  • Is it not possible to use an image viewer instead? It should be possible to "scroll" through images with the forward and back arrow keys, deleting the ones you don't want. The Dolphin file manager can scale thumbnails from 16px up to 256px but even that may not be enough to distinguish between two closely similar images.

    Does this answer your question? Nautilus Thumbnails Size Fix

  • @vanadium maybe this work by using dconf. But that is nothing that my grandma would understand. An simple solution would be nice.

  1. Open a terminal and enter the following commands.

    In case you had enabled experimental views in Nautilus, we will first disable it.

    Then we set the desired "standard" icon thumbnail size. In this example, I've set thumbnail icon sizes to 400, but you can set it to whatever you want.

    gsettings set org.gnome.nautilus.preferences use-experimental-views false
    gsettings set org.gnome.nautilus.icon-view thumbnail-size 400

    Note, if you want to make the above changes using a GUI application instead of a terminal, you can disable experimental views in Nautilus' Preferences menu. Also, you can install the package dconf-editor and set both fields using the Dconf Editor's GUI.

  2. Restart

    To make the changes effective kill the Nautius process (or simply restart your computer).

    killall nautilus
  3. Open Nautilus and navigate to the pictures folder you want to view.

  4. Click on the "Icons View" grid in the header bar.

    Click on the "Icons View" grid in the header bar

  5. Here is the thumbnails view with larger icons (100% = 400px). You can still scale them bigger or smaller from the new large default size you had set in step 1.

    You can query gsettings for the key description: gsettings describe org.gnome.nautilus.icon-view thumbnail-size... "The default size of an icon for a thumbnail in the icon view when using NAUTILUS_ICON_SIZE_STANDARD size."

  • Nice! In step 2, terminating and restarting Nautilus instead of rebooting work well.

    Sometime between 18.04 and 19.10 the thumbnail-size key seems to have been dropped

Almost always modern glossy GNOME use strange non-intuitive methods for simple problems.
Seems to be limited by design.
You can see other snap problem as a good example of modern Nautilus "design".

It is time to switch to MATE or Cinnamon with their file-managers

  • Caja

    Caja on Ubuntu MATE 18.04.1 LTS

  • Nemo

    Nemo on Ubuntu MATE 18.04.1 LTS

as both they have 400% zoom.

IMHO: if you want to use computer for work without bells and whistles - do not use GNOME at all.

    If I ever switch away from Kubuntu, it would be to Ubuntu Mate. I have the minimal install of 18.10 in a VM and it's extremely user-friendly.

    you said "if you want to use computer for work without bells and whistles - do not use GNOME at all." I want it to be simple and flexible. Thank you for your hint. I will have a look at Mate.

    @vanadium True this isn't an answer to the question but it is valid as a "Frame Challenge" as I just learned about yesterday: askubuntu.com/questions/1098530/… Dec 9 '18 at 17:47

Here is a script that is easier for "grandma" to use:

zoom - Script to set Nautilus Thumbnail size


# NAME: zoom
# DESC: Change nautilus thumbnail size based on parameter 1
#       For Ask Ubuntu question: https://askubuntu.com/questions/1097934
#       /nautilus-show-images-with-more-than-200-size

# DATE: December 7, 2018

if [[ $# -ne 1 ]]; then
    echo "Usage: 'zoom 999'" 
    echo "Where 999 is zoom factor, eg 400 = 400% zoom"
    exit 1

gsettings set org.gnome.nautilus.icon-view thumbnail-size "$1"
nautilus -q

exit 0

Installation and Usage

Place the file zoom in your search path.

Mark the file executable with chmod a+x /search-path-name/zoom

Call the script from terminal using zoom 999 where 999 is the zoom factor. For example zoom 400 will have nautilus zoom by 400%.

The script can be enhanced to use zenity for a desktop shortcut with GUI pop up window that prompts for zoom percentage.

    Grandma does not know how to create a script with gedit or vim. She does not know the command chmod(). She has old and weak eyes and all she wants is to see her grandson baby smile.

  • The bash script is an easy method of changing zoom factor over 200%. After one-time setup, to copy and paste above script, you won't have to type "hard to remember" commands in the terminal. I was mislead by the "grandma" comments because I thought you were going to set this up on her computer. Dec 7 '18 at 15:36
  • You are right. You can always walk around obstacles. Usability means for me "don't make me think". Maybe I should buy a commercial os for my grandma.

  • @guettli types the script for granny, sends it as an attachment in email, tells her to save in ~/bin and types the chmod next time he visits granny. ;-)

    @guettli Wouldn't it be much easier if you open the image with image viewer? Navigate with arrow key and delete with Delete key. You gotta see the image in full screen or a maximized window, albeit you can only delete the images one by one. Though, it can be argued if you enlarge the thumbnails large enough you'll only can see them two or three at a time.
