I am using Tuxedo OS which is using kde and I am having trouble when I go to logout screen, it is white no matter what theme I use, can someone please help or point me somewhere to fix?
are you changing the SDDM theme or the global theme?
click on the desktop and type SDDM … then go to the setting page from the search result.
i use monochrome which you can find by going to the Find new SDDM themes button and doing a search there
Have you tried changing the ssdm wallpaper yet?
You should be able to get the dark background with the help of the GUI by changing
→ System Settings → Appearance → Global Design
from one of the TUXEDO designs to a Breeze design.
That has changed it at least in my TUXEDO OS when I tried it 5 minutes ago…
Thank you guys for the tips but today I switched to Debian 12 using the same theme and no problem was able to change wallpaper and its dark blur like it supposed to be.
