<div class="moz-cite-prefix">As far a Kmag goes, one nice side
effect of using it is that if the projector is a lower resolution
than your laptop it will pan the display around so that you can
see the whole screen so you aren't stuck with only a partial
screen like what happens when you mirror the display, so it can be
good thing even if your aren't using Libreoffice Impress.</div>

For your dual monitor situation, are you using a single head (1
video card) or dual head (2 video cards)?
<br>
<br>
Keep in mind I'm talking cards, not ports on the cards. (Video
cards can have multiple ports. Mine has 2 x HDMI and 1 x DVI)
<br>
<br>
Attached is a screenshot using Impress on a single head
configuration with dual monitors. Notice one monitor is the actual
presentation (right side) and the other monitor is the presenter's
screen (left side).
<br>
<br>
I accomplished this by pressing the F5 key (which is the key to
start the presentation).
<br>
<br>
Now, the reason for the question. When you run a dual head
configuration, it gets really tricky to extend desktops between
the heads. This gets especially wonky with nVidia cards, and it
architecturally makes sense on why there's a limitation (memory
space). The only way I've worked around it was to run two
desktops, one on each head. And I was only able to accomplish that
successfully using XFCE. Gnome and KDE didn't play well with
multiple head configurations for me.
<br>
<br>
I hope this helps. I run Ubuntu 18.04 and the screenshot attached
was a default install allowing Ubuntu to set the dual monitor
configuration. I can likely exchange some config files with you if
you wanted to explore how it self configured. I can say with this
setup, I can run steam games on one monitor while watching Netflix
on the other (which is the typical style of use for multiple
monitors). And as you can see, Impress will allow me to have a
presenter screen and slide show screen.

The reason for this is that I was running Libreoffice Impress in
dual monitor mode so that I can see my notes and the next slide.
I could solve the problem by just mirroring the display, but
that causes problems by eliminating my notes and other
resources. There is also the possibility of using a tablet to
control the presentation, but that might not be reliable at
SCaLE when I do the presentation again.
<br>
<br>
So what I need is a way to display a program on both monitors at
the same time without having to mirror the display.
<br>
<br>
I think I might have a workable solution by abusing the kmag
program and setting it's magnification to 1:1, but I wonder if
there is a better or more purpose built solution to accomplish
the same thing. If there is, great, I'd love to hear about it,
if there isn't then this message can serve as a possible
solution for others to increase the quality of their
presentations.
