What happens in an ubuntu session is -
After logging in, no display. If the session is left inactive until display is put to sleep, then awakining it thru keyboard or mouse brings back a visible display. (default is 5 min. of inactivity
A simple startup script via startup applications demonstrates -
script in ~/bin
#!/bin/bash
xset dpms force off
xset dpms force on

It's been suggested that xorg.conf needs some serverflags, ie.
Section "ServerFlags"
Option "BlankTime" "0"
Option "OffTime" "0"
EndSection
Though not effective here as a standalone section & if there is an xorg.conf solution then it needs to be patched into ubuntu- drivers- common
