How to copy wallpapers in default backgrounds folder ? What file explorer?

[rogierx]

how to copy-paste my own wallpapers in the default wallpaper folder? File explorer refuses to paste ...

LM20.3 cinnamon with kernel 5.15 and nemo file explorer

1. started terminal and

Code: Select all

sudo nemo

2. copy-pasted in /usr/share/backgrounds/

The questions are:
A. why does Linux Mint need administrator privileges to copy a few simple .jpg's ?
B. why is it so hard to determine WHAT file explorer we have at hand? The name 'nemo' is nowhere in the menu.

A very bad command. Sudo in conjunction with any graphical program leads very quickly to problems with the ownership of your own files. Possible result in the worst case: You cannot login into your own account. So do it never again.

Actually you do not need something like this command for your task. Simply copy your own background pictures in your picture folder, open the background settings and select in the left pane the picture folder (listed at the bottom) as the source for your backgrounds. You can also set the files into a sub-folder of pictures, add this sub-folder to the background settings (note the + sign at the bottom on the left pane) and your done.

To your additional questions:
A. The point are not the "simple jpgs", but the fact, that this is a system folder. But as said, you can place the simple jpgs into your home and you got what you want.

B. There is partially a problem, because Mint tries to localize program names, where this gives more trouble than usefulness. But in this case: Nemo menu -> help -> about. (BTW: a quite usual method, even in Windows.) Be surprised, what you read there.
Besides that: If you open the menu and enter in the search box nemo you get it also (although the name in the menu is different).

If I follow these steps here on my German speaking Linux mint 19.3 Cinnamon and enter nemo in the search field of the Mint Application menu, then the found application will be displayed as "Dateien", in English "Files".

Once you have successfully launched the file-manager, in the menu going to "Hilfe" => "Über", English "Help" => "About", will surprisingly reveal that this is Nemo, version 4.4.3 here on LM 19.3, some higher version on LM 20.3.

Thanks I found it under 'other locations' and then the menu forgets about /usr/share/ which is good because I dont like those pictures.

Thanks that works but I would prefer another way in Mint, when you start a brand new operation system and you have no clue what the NAME is of the file explorer. It used to be nautilus or konqueror. So now: I dont start the Nemo menu (because I have never heard of Nemo), but start the suggested nameless File Explorer -> help -> about, and only then I find out it is Nemo. After that I can open up a terminal and GUESS that I can run commands starting with 'Nemo'. I suppose we should end here as the topic is changing

In English, at least, one doesn't need to know the actual app name of the file manager. Searching on Menu for File ... will find it.

Also, in this particular case, there's an icon for File Manager on panel, so no need to search for anything.

Additionally: to use a file manager as root, rightclick on an empty area in the right side and choose 'Open as root'.

There was not the problem to find the file manager, the OP used it already, see the first post. His question was how to find out, how to find the name inside of the program.

[antikythera]

it's better to store them in /home/.local/share/backgrounds/foldernameofyourchoice. you need to show hidden files to see /.local/share in your home directory. backgrounds won't be there but you can create the folder and any folder inside it you like to separate categories of your own images. After doing that, your backgrounds will be available to choose in the dialogue along with the ones you do not like.

to start as root you can use this command in a terminal also

Code: Select all

pkexec nemo

It will ask for your password.
The file structure of Linux keeps pretty much all content out side of your users home directory as needing root privileges.
this is for security reasons. It makes it much harder for people with malicious intent to destroy or modify you file system and infect your computer.
It's one of the reason Linux is more secure that some other OS's. In any event you need to learn more about the Linux file system.
