Sorry, I think I need to reopen this bug.
Bug id=104330

If my operating system is CentOS 7.3 or update to kernel 4.16.7-1, it is normal. 
But when my operating system is CentOS 7.4 or update to kernel 4.16.7-1, it is normal. With kernel 4.16.7-1, when I plug in the VGA cable after entering os, the screen stops on the background but no login interface. See the picture of attachment.
