After a recent upgrade when I unlock my screen, the lock screen has a wallpaper background that I never had before, it was always black iirc but now it is the wallpaper Elarun where is this configured?

thanks,

It's the default wallpaper specified by the current Plasma theme. See also this bug report.

as always thanks,

Here a workaround from the openSUSE mailing list if someone cares http://lists.opensuse.org/opensuse-kde/ ... 00082.html

A terribe workaround would be to modify
/usr/share/kde4/apps/ksmserver/screenlocker/org.kde.passworddialog/contents/ui/main.qml
file.
Changing
- source: theme.wallpaperPathForSize(parent.width, parent.height)
+ source: "1920x1080.jpg"
and adding picture named 1920x1080.jpg in
/usr/share/kde4/apps/ksmserver/screenlocker/org.kde.passworddialog/contents/ui/
dir, would change the wallpaper for locker only, but this obviosly can't be
used on distro level, and would be overwritten on upgrades.

As pointed out above the default wallpaper is specified in the desktop theme.

I therefore made a copy of the system Oxygen theme by creating a new folder in
$HOME/.kde/share/apps/desktoptheme/
and linking into it all folders and files in
/usr/share/kde4/apps/desktoptheme/oxygen
apart from file metadata.desktop which I copied and changed the name of the default wallpaper.

I then selected the new theme and voila - the locker now uses my preferred wallpaper

This is not an optimal solution, but one way is to overwrite the image that (by default) kde points to.
On my gentoo system, I went into the folder:

/usr/share/wallpapers/Elarun/contents/images/

(Elarun is the default wavy blue wallpaper you get at login and when locking screen)

I created a backup of the file (2560x1600.png) and copied my desired wallpaper into its place.

Now it functions as I desire. I wish there was a better way that I could do this.

Good luck.

I changed my default theme and it did not apply to my locked screen wallpaper. There appears to be a system default (it might affect the icon loading screen when you log into your machine as well, I turned mine off)

To do it properly, using any image:

Copy an existing wallpaper profile as a template:
cd .kde4/share/wallpapers/
cp -r /usr/share/wallpapers/ExistingWallpaper .

Change the name in the directory, and edit the .desktop file:
mv ExistingWallpaper MyWallpaper
vim MyWallpaper/metadata.desktop
[Desktop Entry]
Name=MyWallpaper
X-KDE-PluginInfo-Name=MyWallpaper

Remove existing images:
rm MyWallpaper/contents/screenshot.png
rm MyWallpaper/contents/images/*

Copy new image in:
cp MyWallpaper.png MyWallpaper/contents/images/1920x1080.png

Edit the metadata profile for the current theme:
cp .kde4/share/apps/desktoptheme/MyTheme/metadata.desktop metadata.desktop.orig
vim .kde4/share/apps/desktoptheme/MyTheme/metadata.desktop
[Wallpaper]
defaultWallpaperTheme=NewWallpaper
defaultFileSuffix=.png
defaultWidth=1920
defaultHeight=1080

Now lock the screen and see if it worked!

A "terrible" workaround would be to modify the screen lock configuration file
/usr/share/kde4/apps/ksmserver/screenlocker/org.kde.passworddialog/contents/ui/main.qml

Changing
- source: theme.wallpaperPathForSize(parent.width, parent.height)
+ source: "1920x1080.png"

and adding picture named 1920x1080.png into the dir

/usr/share/kde4/apps/ksmserver/screenlocker/org.kde.passworddialog/contents/ui/

which will change the wallpaper for locker only (but this obviously can't be
used on distro level, and would be overwritten on upgrades).

This method worked best for me in Kubuntu (with KDE 4.12), and I am happy with it. It was not necessary to use a 1920x1080 image, and I used the 1366x768 Ariya image that had been used on my screen in the past (and which fits my laptop screen). It is important to include the quotation marks around the filename (which gave me a troubleshooting headache when I forgot them).

I don't like the Elarun images, so I ended up copying all the (bland, but preferable to me) Ariya images into the Elarun folder (in /usr/share/wallpapers/Elarun) anyway (though this wasn't necessary for the screen lock changes).

Why you don't use systemsettings - Harware/Display and monitor/ Screen locker - Desktop widgets (without widgets) ?

Hello.

There is another workaround.
First you need to copy default wallpaper to $HOME

Code: Select all

cp -r /usr/share/wallpapers/Elarun ~/.kde4/share/wallpapers

Then you can easily replace ~/.kde4/share/wallpapers/Elarun/contents/images/2560x1600.png with image you want.
You may also need to clean cache

Code: Select all

$ rm -r /var/tmp/kdecache-$USER/plasma-wallpapers/usr/

Running KDE 4.12.2

I just lock widgets and settings stay the same after reboot.

Because I want to use a screen saver as my locker, but when I get the unlock display, I want to see my preferred wallpaper and not Elarun.

People, https://bugs.kde.org/show_bug.cgi?id=312828#c11 seems to be best option to get the desired behaviour. But also see my notes under https://bugs.kde.org/show_bug.cgi?id=312828#c13 else the above may not work (for your screen resolution).

I've done this and it's weird that I've cleared all caches but every time I change my wallpaper it reverts back to the elarun picture. I think maybe there's something else I need to do? I miss my old Homer Simpson wallpaper.
