When impress running presentation in fullscreen on secondary display unity pannel is visible

[George Shuklin]

When impress is running presentation on secondary displays, it not always display 'over' the uninty menu (at the screen top). This happens if focus is in main impress window (on primary displays) and presentation is running on secondary.

Steps to reproduce:

1) Set up a dual-screen configuration (with different content on each display)
2) Run Impress, open/create presentation
3) Set up in 'Slide Show' -> 'Slide Show Settings' in 'Multiple displays' presentation display (the second one).
4) Run presentation (F5)
5) Press Alt-tab to switch to any other application
6) Return to Impress (all that time presentation is still running on secondary display)

Expect:
Nothing displays over presentation

Got:
Horizontal bar with notification icons, date, login button and so on displayed over running presentation.

I'm not so sure this is actually a bug. When the presentation is focused, it is full screen and is on top of all windows and Unity's menu bar. When another app is focused, it's on top of all other windows and the menu bar is visible since the other app isn't covering the menu bar. This behavior does not even require a second monitor to reproduce.

If this behavior is a bug, I think it should be reported about unity, not libreoffice.

I do admit that it would be convenient to be able to work on a second screen while a presentation is showing on the first screen without the menu bar covering the top few pixels, but the tradeoff is that it might make it impossible to use the menu bar when any app is fullscreen without first un-fullscreening the app.

can you please attach screenshot or a video of the problem that you are facing?

Affects me too.

Left is my laptop screen, right is projector output.

I'm attaching a screenshot of my setup, I want to be able to control libreoffice presentations from openlp, but when I click on it to change slides, libreoffice loses focus and the unity bar appears on top of the presentation, making it look very unprofessional.

OpenLP properly covers the unity bar output of its own content. Unity bar on top of presentation also happens with libreoffice alone.

Workaround:

sudo apt-get install compizconfig-settings-manager

Alt+F2 to summon the command panel, then type ccsm, hit enter

A warning will pop up about how ccsm is an advanced tool, dismiss the warning

Under the "General" heading, go to "Composite"

Pick "Unredirect Fullscreen Windows"

After you select this Unity may or may not restart, it's okay since the setting will be applied automatically anyway.
