VGA display program?

Was wondering what trisquel gnu/linux runs when a vga cable is plugged in to another device (monitor, projector, etc.)
I am presenting some research and plan on plugging in to a projector.
I tested it this morning in my classroom, and everything displayed properly, but the system must first start with the vga cable plugged in order to work.
I ran 'ps aux' to look around for the program that runs to output the display, but did not have enough time find it.
Help is much appreciated.

Have you tried the settings under displays?
Some packages that might come handy include
libreoffice-presenter-console
pdf-presenter-console
Those will allow you to see onscreen the next slide and a clock and your notes while the slide is on the projector.
Also some laptops have hotkeys (e.g. Fn+something) to turn on/off the outputs.
Good luck with the prez and have fun!
Didn't see anything under displays, in Gnome
My GUI is very minimal,as I use i3, but do have Gnome still installed if I need it for emergency.
I have been trying to make more use of the command line/bash.
Thanks for the other recommendations, though.
The prez went great by the way!
It was part of my research paper for my final.
And it was actually on Free Software.
While the class decided to present on the classroom computer with Microsoft Power-point, I plugged my x200 from ministry freedom in and presented.
I made many aware of what they are missing out on, and even had many questions of interest after.
It felt great to educate those who have been abused by their software.
$ aptitude show libreoffice-presenter-console
This package used to contain the LibreOffice presenter console. It has been
integrated with LibreOffice Impress 4.0. You can safely remove this package.
;) Good to know! How the time flies...
I believe the X server takes care of multi-screen display. Not a separate process.
I want to know how to activate whatever takes care of the multi-screen display.
If my laptop is already on and plug in the vga cable to the projector, nothing happens.
ONLY when i turn the computer on with the vga cable plugged in is when the multi screen happens.
If using "Displays" (in the "System Settings") does not work, I would try with 'xrandr' in a terminal. Does it list the two screens when called with no argument?
I will get back to you on that.
Need to get to the projector to test that.
Thanks Magic Banana.
Hmmm, I typed 'xrandr' but command not found...
I have the same issue when my laptop is on and off it's base (connected to DVI).
Didn't go through the issue yet, but I want to try to refresh xrandr, if that makes sense.
The reason is it's always right when I turn the laptop on.
It doesn't when I try to put it on or off the base/DVI (connect/disconnect from external screen).
Maybe playing with this could help: https://askubuntu.com/questions/356621/refresh-display-settings-using-xrandr-laptop-screen-off-external-screen-on
But to make a script out of it, I would need to identify the trigger that makes the xrandr config change when I plug or unplug the external screen.
What desktop environment do you use (GNOME, KDE, Xfce, LXDE, …)?
Maybe you'd like to try installing arandr?
