That boot log looks complete, so what are the symptoms of the failure?

After system boot, the screen can't go into the login but stay at somewhere, which I take a picture in the attachment. 
At first I said system boot fail because after boot the machine can't be accessed by ssh, but now I find it can be accessed by ssh, maybe yesterday I didn't wait so long time to access it. 
So now the sysptoms are: 1. the screen can't go into login. 2. the machine can be accessed by ssh.
