a problem when use plymouth

[xiaomei.wang at i-soft.com.cn]

hello, can you help me with a problem 
when I use plymouth there is a black screen between the plymouth-theme(I now use spinner) and login manager
my kdm.service is like
[Unit]
Description=KDM Login Manager
Documentation=man:slim(1)
Conflicts=getty at tty1.service
After=systemd-user-sessions.service getty at tty1.service plymouth-quit.service
Conflicts=plymouth-quit.service

[Service]
ExecStart=/usr/bin/kdm vt1
Restart=always
IgnoreSIGPIPE=no

[Install]
Alias=display-manager.service
~

I don't know what's going wrong.
Looking forward for your reply.
