Hi.
Was a while when I change my wallpaper using the personalization.
Now I want to change them with another ones, but, when I scroll down, in terminal shows this message:
ERROR:dbus.proxies:Introspect error on :1.69:/com/deepin/individuation_settings: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: 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.
And then, the dialog keeps white and I can't change anything.
Is there a solution for this?, exist a configuration file where I can set them "manually"
Thanks and keep the good job!
