I am having the same result: blank screen with a 'X' (mouse cursor).
I preformed the following action to receive the above result:
Created and added the following lines to /var/lib/tftpboot/ltsp/i386/lts.conf
[00:0F:20:28:10:7D]
LDM_USERNAME=ws001
LDM_PASSWORD=password
Without the 3 lines in lts.conf the remote terminal boots to the standard login screen.
