+Subject: [PATCH] systemd/lxdm.service: remove plymouth-quit conflicts
+
+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.
