Bug 1711001

I don't meet this issue on my system. Does 'org.freedesktop.Notifications' name exist on D-BUS session bus?
And which program serving this name? On my system it is /usr/libexec/deepin-daemon/dde-osd

[hufon@ipponhufon ~]$ qdbus org.freedesktop.Notifications /org/freedesktop/Notifications org.freedesktop.DBus.Introspectable.Introspect
Error: 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.

The same command on kde
[hufon@ipponhufon ~]$ qdbus org.freedesktop.Notifications /org/freedesktop/Notifications org.freedesktop.DBus.Introspectable.Introspect

Was /usr/libexec/deepin-daemon/dde-osd running on your Deepin environment? Any strange log entry found in user journal?

no, dde-osd don't run in my system.
But if i start it manually in a terminal, it works! It seems that dde-osd is not started automatically.

Where can i found the user journal?

'journalctl -b --user' will print all user log of current system boot.

Is dde-osd running at a freshly logged-in Deepin session?
Does com.deepin.dde.osd name exist on D-BUS session bus?

No, dde-osd is not running at a freshly loggin-in Deepin session.

but sometimes, it loads after 1,2 minutes, sometimes not.

I can reproduce this now. Just login DDE through sddm.

Nope, i've switched to ssdm.

The loading of dde-osd is still random...
Sometimes, it never loads, sometimes it loads 5min later after login.

Hi, 

There's still a problem.

When my computer is going to standby mode, the dde-osd daemon is no more present, and it'no relaunched.
