Does not include a model number, and looks like you copy-and-pasted it
from somewhere.

You are *still* asking me to do your work for you.

I am not some member of Ubuntu staff, you know. Nobody here is. Ubuntu
does paid support for corporate customers. That's not us.

We're all just volunteers, trying to help.

Demanding that we think for you is rude.

So, here is what I did FOR YOU which you could have done yourself.

I Googled your model number, went to Lenovo's website and looked up
the product manual.

http://support.lenovo.com/cz/en/products/Laptops-and-netbooks/IdeaPad-Z-Series-laptops/IdeaPad-Z570?tabName=Documentation&linkTrack=Mast:SubNav:Support:Documentation|Documentation&beta=false

I got this:

https://download.lenovo.com/consumer/mobiles_pub/lenovo_z370z470z475z575z570_ug_v1.0_english.pdf

It says:

<<

Enabling NVIDIA® Optimus™ (on select models) - - - - - - - - - - - - -
- - Optimus is a GPU switching mechanism which automatically switches
the active GPU to perform image-rendering tasks. If no
graphics-intensive programs are running, the integrated GPU will be
selected as the active GPU to preserve battery life; if you start
high-definition movie playback or a 3D game, the image-rendering task
is automatically switched by Optimus to the discrete GPU to produce
high graphics performance. Check the GPU indicator: if the indicator
is off, slide and release the GPU switch to enable Optimus. When
Optimus is enabled, switching between integrated and discrete GPUs is
performed automatically without user intervention. However, you can
customize settings through the NVIDIA control panel to make the
desired GPU active to perform image-rendering tasks for certain
programs. For details, search for Optimus in the help system of the
NVIDIA control panel. Note: This password can be from one to seven
alphanumeric characters in any combination. Note: To enter BIOS setup
utility, press F2 when the Lenovo logo appears on the screen while the
computer is starting up. Notes: • Optimus is not supported by all
operating systems. Currently, Optimus is supported by Windows® 7. If
you are using another operating system, such as Windows® XP, it may
not be able possible to enable Optimus. • Optimus is not supported by
all media players and video compression standards.

So there is a physical switch. You have not mentioned this or which
model you have. Some have it, some do not.

I also looked on Amazon:

https://www.amazon.com/Lenovo-Ideapad-1024AMU-15-6-Inch-Laptop/dp/B006M9ZXDW

This says that at least 1 model does not have an nVidia chip and so no Optimus.

It also gives the GPU model, which you did not bother to do.

Intel HD Graphics 3000

So then I Googled again:

"intel hd graphics 3000 support multiple monitors"

First hit:

http://superuser.com/questions/350052/is-it-possible-to-use-three-screens-with-intel-hd-3000-integrated-graphics

Which says, no, the HD3000 GPU only does dual-head, not triple-head.

So you could have answered this yourself with 2-3 Google queries
rather than making us do your work for you for 3 days.

What? If it is the same motherboard, no, they put in a new board, they
did not desolder and remove chips from it, which is [a] ridiculous [b]
would make it not work any more.

If they said it's the same board, either it's the same board or
they're lying, and if you don't trust them, why would you trust a
bunch of random strangers on a mailing list?

I don't know, it's your laptop! Don't you know what you bought? Did
you or didn't you buy the model with GPU switching?
