Background Wallpaper

Hi,

I have a Rocky Linux Installation but cannot change the background. Is that normal?

Thanks

I just want to add myself to this. I too am running the Rocky Linux provided by Blackmagic. And I too want to change the background image.

I have looked in the regular gnome settings. I see Background there and I can open a menu that SEEMS to let me change things. But as soon as I press select. It goes back to the BMD desktop background

I have also looked into the gnome tweaks thing. Here I also see the BMD desktop background. I seem to be able to change that setting. But when I exit the tweaks app... nothing has changed on the actual desktop.

I mean. Sure. I guess. Blackmagic might like to have a default image there, and I wouldn't be so adamant on changing it... if it wasn't for the fact that I have 4 screens that aren't arranged so that it can be a perfect total 16:9 canvas. So everything is stretched out. If I could at least make the image not span across all screens, it would look so much nicer. But I cannot seem to find any way to do even that.

I might add... I can't speak for the original poster. But for myself. I am very new to Linux. so if there's something obvious that I, or the OP is missing. Please...

Ok, I have now resorted to trying to just replacing the default BMD logo wallbaper with another jpeg with the same name. That resulted in pure black background instead of the image I wanted... but... Unless anyone can say anything else, I will leave it as that, because at least it's not an uglified stretched out background.

This is happening because the gnome background setting is locked via a policy in
Code: Select all
/etc/dconf/db/


I had the same issue where I could not change the background from the default Blackmagic desktop background, but I was able to fix it by doing the following:

Look for a lockdown file:
Code: Select all
grep -r 'org/gnome/desktop/background/picture-uri' /etc/dconf/db/


Above command returned something like this for me:
Code: Select all
/etc/dconf/db/local.d/locks/background:/org/gnome/desktop/background/picture-uri

Code: Select all
Binary file /etc/dconf/db/local matches


Since the output of the grep command contains the below, then it means it is locked
Code: Select all
org/gnome/desktop/background/picture-uri


To unlock do the following:
Code: Select all
sudo vi /etc/dconf/db/local.d/locks/background


Comment the following line by putting the # sign in front of it or delete it entirely:
Code: Select all
#/org/gnome/desktop/background/picture-uri


Rebuild the dconf database
Code: Select all
sudo dconf update


This should unlock the gnome background settings and you should be able to set the background image / wallpaper again.

Can confirm. It works!

Though, I did use nano instead of vim (because I cannot wrap my head around the needlessly cryptic moon-logic interface of vim) and I also went ahead and commented out all the options in the file. Because I didn't really choose Linux to have things locked away from me ;)

Code: Select all
# List the keys used to configure the desktop background
#/org/gnome/desktop/background/picture-uri
#/org/gnome/desktop/background/picture-options
#/org/gnome/desktop/background/primary-color
#/org/gnome/desktop/background/secondary-color
