Created attachment 107614 [details] Login screen settings OS: Kubuntu 16.04 amd64 Plasma: 5.8.7 Can not change background color. Open 'Login screen (SDDM)' from main menu. Click on 'Background' > 'Load from file' > choose png/jpg file with resolution as my notebook has. Click 'Apply'. But nothing changed. I still see default blue background.
Can you run systemsettings5 from a command line, reproduce and send me the output. Do you get a prompt for a password? Can you include your /usr/share/sddm/themes/breeze/theme.conf.user Then set this status back to "unconfirmed"

>kf5.kauth: "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken." Save Failed Well that explains our problem. The bit of code that runs as root to update the SDDM settings is either crashing or getting blocked. That's tricky to debug. You can try running: sudo /usr/lib64/libexec/kauth/kcmsddm_authhelper then clicking apply from system settings in the next 10 seconds. It should use the executable we started and can then get output. Or even a gdb trace if possible?
I have kcmsddm_authhelper in only specific path: usr/lib/x86_64-linux-gnu/libexec/kauth/kcmsddm_authhelper Again record video: https://youtu.be/86ZEUATBlp8 kcmsddm_authhelper have no output in console. Sorry, I have no necessary skills and do not understand what'is gdb and what I need todo more.
Hm, I'm confused. I'm power off my notebook. Then power on and on login I see correct new background. But if I lock screen/sleep device and switch on again I see default blue background. Is it correctly? Or in all cases should be one background?
