I'm trying to change my wallpaper on Deepin Linux (the X server is Deepin Desktop Manager (dde)) with the command line. I can do it with the command gsettings set com.deepin.dde.appearance background-uris but I need to wait for a user logout/system reboot for the new wallpaper to be displayed.
How could I solve my problem — is there a command which reloads the wallpaper or something like this ?
