Anybody able to set login background with Plasma 6.7?

Issues & Assistance
1

Hey guys! Updated to Plasma 6.7 today and figured it was time for a new login screen background. When changing the wallpaper, I get a password prompt when I click “Apply”. After that, when I close the Login Screen dialog, I get another password prompt and then on reboot, the login screen background is the Plasma default instead of the picture I chose. Weird.

I had the problem already in Plasma 6.6.

I tried making a theme.conf.user in /usr/share/sddm/themes/breeze with the following contents (as described here):

[General]
background=“/home/[myusername]/Pictures/zOthers/Wallpapers2560/lighthouse-in-storm.jpg”

No dice.

That said, I don’t know if SDDM is even the login manager I’m using and I’m not sure how to find out.

default is plasma-login, not sddm

I have installed the now-standard Plasma login manager, and since version 6.7, I am also unable to change the background image.

I’m using sddm by the way.

Ive got the same problem, and was able to fix it.
/var/lib/plasmalogin/wallpapers/
The owner of this folder for me was root, it should be plasmalogin manager,
No idea how or why it happened but after changing the owner of the folder it worked again.

Gave full permissions to anyone as a test and it woirke, after checking the folder again it had 755 and plasmalogin as the user, so simply changing the user to plasmalogin should fix it.

This used to be the case for me, but now I have a strange issue where I have two login backgrounds, one for logging in after startup, and one for logging in after sleep, both are different images

I think when waking up from sleep, what you’re seeing is the lock screen. That has its own settings in KDE. Does that help?

Sick! That’s the solution. Thanks :slight_smile:

I didn’t realise they were different, thank you

Still completely unable to apply the wallpaper I chose on login screen. I select the new plasma 6.7 default wallpaper and “always use light variant”, yet when I go to login screen it shows the light variant of plasma 6.6 default wallpaper instead.

Changing the login screen to default settings does revert to the plasam 6.7 wallpaper I wanted but in dark mode, not light. I’m completely unable to change to light mode 6.7. I don’t know how selected the 6.7 wallpaper ends up displaying the 6.6 one…?

For Plasma Login Manager in Plasma 6.7, I do this. Works every time.

Settings > Login Screen > Configure Apperance > Add > Choose Image > Select New Image > Click Apply > Enter Password > Done

Thank you!

sudo chown -R plasmalogin:plasmalogin /var/lib/plasmalogin/

This seems to have fixed it indeed.
