[Solved] Lockscreen Wallpaper

BackGammon · 2026-05-18 23:11:01

Apologies if this has been answered already... I wasn't able to find an applicable solution.

I have been able to change my Grub and Login wallpaper but I haven't been able to change it on my lockscreen.

Can someone point me in the right direction?

^That's a tricky one because it comes from an XFCE setting that's alien to our system, and we have to use an xfce4-desktop config file to set the xfce4-screensave background image, even though we don't actually ship xfce4-desktop.

Go to ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-desktop.xml, find the code blocks that refer to monitors and edit the lines that set "image-path". The setting we ship is "/usr/share/images/bunsen/wallpapers/default/default" which is a symlink to the default Carbon wallpaper. Change those lines as you see fit - probably it's safest to use the same image for monitor0, 1, 2 and 3.

Thank you!

I didn't have the XML file to edit so I tried overwriting the sage-logo_1440x900.png file and it worked.

If it didn't, I was considering installing an xfce distro just to get a copy of that file.

I appreciate you taking the time to walk me through how the sausage is made.

You didn't have ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-desktop.xml?
Did I misspell the filepath? Do you have bunsen-exit installed? That should provide it in /usr/share/bunsen/skel
Maybe you installed on top of a previous system? In that case I recommend running 'bl-user-setup' which will import the default user files. You'll be able to refuse any changes to files you've already edited yourself.

Overwriting the default wallpaper file is of course OK, but it will apply to your desktop and lightdm login too (unless you changed those already anyway).

I know what I did wrong.

I pasted "~/.config/xfce4/xfconf/xfce-perchannel-xml/" into Thunar but I was logged in as root.

When Thunar isn't elevated I am able to see the expected file in the directory.

Sorry for the confusion. I would say that I am still trying to find my Linux legs but the truth is I probably never had them.

I am determined not to give up this time but it looks like I will have to burn my fingers quite a bit.

I know not everybody would agree, but if I'd be allowed to offer one bit of advice, it would be don't log in as root. It makes disastrous accidents much easier. Log in as a normal user, and if you need root permissions to do something on a system file there's usually a menu option somewhere to temporarily invoke the app with root powers.

eg
Thunar: right-click the folder or file and "Open as root".
Geany (if that's your bl-text-editor) while viewing a file: Build > Open as root
Any terminal: just begin your command with 'sudo'.

I agree, I was using Thunar as root to do something that needed elevated access (like copying images to a protected directory) and used the same session.

I do not run as root normally. I should have been more accurate.
