[Ubuntu 20.04] Wallpaper not change

[juanwulu]

Hello there, thanks for the amazing repository.

It's not working on my Ubuntu 20.04 here, and as required the output of $DESKTOP_SESSION is

$ echo $DESKTOP_SESSION
ubuntu

In addition, my system runs on Linux 5.14.0-1042-oem and has applied a custom gnome-look theme.

Thank you.

Since you have a custom gnome-look theme, that can be causing the issue, i think that the theme is dark based and uses the dark colors of gnome. The way to fix is:

Go to /usr/bin in the terminal and open as sudo the file 'dwall' (with a text editor for your choice). Then look for the part of the code where gnome is talked about, (here: elif [[ "$DESKTOP_SESSION" =~ ^(PANTHEON|Pantheon|pantheon|GNOME|Gnome|gnome|Gnome-xorg|gnome-xorg|UBUNTU|Ubuntu|ubuntu|DEEPIN|Deepin|deepin|POP|Pop|pop)$ ]]; then), then the line after this is you have a SETTER... statement, look for the last word in that line which is picture-uri and just change it to picure-uri-dark, looking like this:
SETTER="gsettings set org.gnome.desktop.background picture-uri-dark", then I think it should be fixed

dont mind about the format of the post, im new on github

Thanks for the quick reply. After the change I got the No such key error:

What might be the cause of this issue?

I followed the steps you mentioned and changed SETTER="gsettings set org.gnome.desktop.background picture-uri" into SETTER="gsettings set org.gnome.desktop.background picture-uri-dark" in the dwall file.

you need to change in usr/bin, locate it there and open it with an editor, and make the changes, then go to terminal and try to use dwall

[Roigo21]

oh nevermind, I totally forgot that I told you already the path, then i dont know how it can be fixed, maybe, try with gnome dark theme to change the wallpaper, if it works, you know the problem.

Thanks for following up. I've been using the dark theme the whole time. FYI, I'm now testing on Ubuntu 22.04 LTS with similar settings and it doesn't work as well.

im still a very newbie in linux so i dont know what should i do more to fix that, i can try to install this on my laptop to see if it works (laptop is with pop os 22.04) A sex, 5 de ago de 2022, 01:54, David Juanwu Lu ***@***.***> escreveu:

This did the trick for me.. it would be nice if this was mentioned somewhere in the setup guide. Would this be worth a PR?

I was using Dark theme in Ubuntu 20.04 and experienced this same issue. I changed the theme to Light theme and now I am able to change the background:

gsettings set org.gnome.desktop.background picture-uri file:///path/to/my/image.jpg

[Roigo21]

if you still want to use the dark theme just change the picture-uri in the line you mentioned to picture-uri-dark. A qua, 19 de abr de 2023, 23:15, Joseph W ***@***.***> escreveu:
