I tried to use VNC (remote desktop viewer) on a computer that does not have a monitor but failed. When that computer has a monitor, VNC viewer works fine. Also in both cases, ssh remote access works fine. Could anyone advice me what to do. Is it required that the computer must be connected to a monitor in order for a VNC viewer to access it.
