+When use plymouth[1] with lxdm, the plymouth boot splash screen
+will hang there as lxdm.service conflicts with plymouth-quit.service
+and plymouth-quit will fail to start if plymouth-quit.service and
+lxdm.service start at the same time and it will result in the boot
+screen hang forever.
+
+Consider there is also After setting for these two services, so
+remove the conflicts setting to make the service start as expected.

+Subject: [PATCH 7/8] greeter.c: support to update expired password
+
+Update greeter to work with ui to handle expired password. It checks
+whether password is expired after input user and password. If expired,
+force user to update password immediately. It allows 3 times to try. If
+exceeds, reset to input user.
