Brian,
For your dual monitor situation, are you using a single head (1 video
card) or dual head (2 video cards)?
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)
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).
I accomplished this by pressing the F5 key (which is the key to start
the presentation).
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.
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.
