Good day.

How I can set automatically running xrandr ones X has finished loading?
- I need this to turn off primary monitor.

OR

How I can configure X so that it will suppose secondary as primary and
primary - always off?

OR

Can I specify at early stages of boot process to turn off the
primary monitor so that at X start - it will see only secondary monitor?

Thank You for Your time.

Mmm... check the manual for your xrandr version (man xrand) to review
your options. Basically, it should be something like:

xrandr --output VGA --off

"xrandr -q" will tell you about the attached devices.

There should be also an applet for your DE that let you doing this within
a GUI. At least KDE and GNOME have one.

You will have to play with "xorg.conf" settings by defining some basic
configuration (display mode: xinerama/twinview/clone and layout: RightOf,
TopOf) and also there is "Option ForceMonitors" but "Options" will depend
on the driver you are using.

Now that X is all automated, how about by manually switching off the
display? If Xorg cannot detect the display, it should not configure it :-P
