    Worked perfectly, thank you!

  2. Hi dude,

    why images show in zoom config?

  3. Hi,

    I get a syntax error on the first line;

    syntax error near unexpected token `newline’

    Am I missing something?

    Here is my system.
    Linux red-Inspiron 5.4.0-31-generic #35-Ubuntu SMP Thu May 7 20:20:34 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux


  4. hi when i try to execute the script after inserting the desired images path it says that the image path doesn’t exist. i write the path like this /home/pictures/wallpapers/fag.jpg

    any help is appreciated!! happy linuxing!!

    • Make sure you typed correct file path.

      Open the folder with the picture image and press Ctrl+L on keyboard, it will show you the path in file browser header bar

    • Is you username “pictures” or is pictures a directory in your home? It appears that you may have left your username off the path. i.e.:


  5. I am getting a “sudo: ./focalgdm3: command not found” error when trying to run the script. I tried renaming it to *.sh with the same results.

    • @lavas “sudo bash ./focalgdm3 –set”, and you have to install “libglib2.0-dev” from “”.

  6. @Ji M, your focalgdm3 requires libglib2.0-dev “”, and it works successfully.

  7. after running the script it shows
    “wget ‘’
    –2020-07-04 11:50:34– ‘’
    Resolving (…
    Connecting to (||:443… connected.
    HTTP request sent, awaiting response… 404 Not Found

    • Post updated! The project maintainer changed the script name from to focalgdm.

  8. I have the same Issue as 2 people above, running 2 monitors and the image is spanning the both monitors, I’ve tried using Gnome Tweaks to set it but it doesn’t seem to make any difference, any ideas on how to fix it would be greatly welcomed.

  9. Didn’t work for me. Instead of displaying my picture, it displays a plain one color background.

  10. Worked like a charm, thanks!

  11. make sure ‘p’ is in caps in pictures.= /home/Pictures.
    check if your directory names are proper, that’s all.

  12. Works perfect!!!

  13. worked like a charm, even in 2021 thanks!!

  14. I just select Administration/Login Window from the Ubuntu menu.

    Adjust parameters as needed.
