[quote name="Kunal P.Bharati"]Though I havent used fedora 12 but you can still do this:
You can log in to the system via ssh.

$ ssh user@ipaddress

Then install TigetVNC using yum:

$ yum install tigervnc [/quote]

TigerVNC installed on computer without a monitor. If I try to establish a VNC connection to this computer, the VNC connection window remains black. The End.
I found a solution to this problem using vnc4server but I want this to work with TigerVNC.
