In case of machine which is only booted but no graphical user login has been done yet, nomachine remote may not work. In such cases if nomachine is leading to blank screen then try:

  1. Edit '/usr/NX/etc/server.cfg' and set:
    CreateDisplay 1
    DisplayOwner "saurabh"
    Here replace "saurabh" with appropriate username on the system
  2. Restart nxserver using:
    systemctl restart nxserver.service
