Linuxslaves.com - There is nothing wrong with the stock wallpapers in Deepin Linux and/or DDE (Deepin Desktop Environment). I can easily set my preferred one as wallpaper and lock screen with zero issue.
If I change the wallpaper with a custom picture, it's working perfectly. But, the app launcher, lock screen, and login screen results in black background / no wallpaper.

How to Fix Black Wallpaper in Deepin Linux
After doing some research, I found that the images will be blurred once you set it as lock-screen and saved in /var/cache/image-blur. However it doesn't work with custom images.
Every time you set any custom images as lock-screen, a black images is created in the blur directory. Let's get started!.
Step 1 - First of all, move a your custom image (let's say it named cuswall.jpg) to /usr/share/wallpapers :
sudo mv cuswall.jpg /usr/share/wallpapers
Step 2 - Open file manager and head to var/cache/image-blur.
Right click on empty space > select Open in new window as admin > and remove all the black wallpapers.

Step 3 - Now set the customwall as wallpaper and lockscreen :
Step 4 - Open terminal (Ctrl+Alt+T) then run the following :
cd Desktop
cp /usr/share/wallpapers/cuswall.jpg ~/Desktop
convert cuswall.jpg -filter Gaussian -blur 0x16 cuswall-blur.jpg
This will make a copy and blur the custom wallpaper on your desktop at once.
Step 5 - Rename the blurred image on your desktop to be the same name as the black image in /var/cache/image-blur as shown :
Step 6 - Next, move the blurred image into /var/cache/image-blur to overwrite the black wallpaper :
sudo mv renamed-file /var/cache/image-blur/
Now your app launcher, lock and login screen, looks much beautiful.
These were all to fix can't assign custom wallpaper to a lock and login screen in Deepin. Thanks for reading!.
