<pre>Description:
Impress displays a single, large slideshow across multiple displays when using
the "Slide Show" -> "Slide Show Settings" -> "Multiple Displays" ->
"Presentation display:" -> "All displays" setting.
This applies to all VCL modes (gtk, gtk3, gen). The "gen" mode (X11) only uses
two (2) displays as a single display. This may be due to one display being
offset from the others. The "gtk" modes use all (in my case 3) displays
(ignoring any offsets). In every case, the displays are used as one big single
display instead of several independent displays with duplicate slide shows.
I expect "kde" modes will do the same, but there is currently another
outstanding <a class="bz_bug_link

title="NEW - Impress crashes on slide show using "All displays""
href="show_bug.cgi?id=124484">bug 124484</a>.
1. This may be due to the DE's display control. The displays are not
"unified", so I would expect them to be seen as independent. Using "unified"
should duplicate the screens as expected (untested).
2. This may be due to the graphics driver--in this case, Nvidia. Nvidia has a
"X screen 0" consisting of all the display as well as individual displays
within it. The slide show is probably detecting the "one display to rule them
all"(tm).
Steps to Reproduce:
1. Open Impress with any presentation
2. Set "Slide Show" -> "Slide Show Settings" -> "Multiple Displays" ->
"Presentation display:" to "All displays"
3. Start a slide show
Actual Results:
Slide show is shown across all displays as one big show.
Expected Results:
Each display shows a duplicate of the slide show.
Reproducible: Always
User Profile Reset: No
Additional Info:
This may need to be set as an enhancement.
There is a use case for each of the following:
1. "All displays as a single display" -- all displays are interpreted as a
single display to present one big slide show. This is the current
functionality (mostly).
2. "All displays as individual displays" -- each display is considered separate
to present duplicate slide shows on each monitor.</pre>
