Change background of login screen

[fixit7]

Is there a GUI way of changing background of the login screen?

All I found was a script.

Thanks.

System->Preferences->Look and Feel->Appearance?

Hi UM22.04 and my appearance section doesn't show option for Login Screen just themes for desktop. OP asking for GUI method.

Found this alternate idea in a previous post on the group:

Kind of a hack, but it works.

I do not understand how to change the image file.

Your screenshot just shows the directory.

Thanks so much. I found the answer here.

GUI to Change Background Arctica Greeter (Login Screen) on Ubuntu-MATE 22.04

Ah zenity... I haven't run zenity a loooong time. You can use sudo and zenity to ask for password. zenity --password | sudo -S "command" -S read from stdin In a script something like this: if [[ "$EUID" = 0 ]]; then echo "already root" else sudo -k # make sure to ask for password on next sudo if zenity --password | sudo -S true; then echo "correct password" else echo "wrong password" exit 1 fi fi # Do your sudo stuff here. Password will not be ask…

Ya I was just saying rename that current file to .old and then put your chosen image in that directory, change the name to match the old file.

/usr/share/backgrounds/ubuntu-mate-jammy

Change the name of your chosen image to:

Jammy-Jellyfish_WP_4096x2304_Green.png

Like I said, more of a hack than using a script. In any case, it worked for me. I am glad you found your answer.

Hi @mickee,

/usr/share/backgrounds/ubuntu-mate-jammy/Jammy-Jellyfish_WP_4096x2304_Green.png is a part of ubuntu-mate-wallpapers-jammy package. If this package gets reinstalled, your modifications will be lost. Path to login screen background is stored in /usr/share/glib-2.0/schemas/30_ubuntu-mate.gschema.override file.
