Description Johan Vromans 2013-06-04 09:59:52 UTC
On a system with a nVidia graphics card, nouveau driver, two monitors, Impress fails to control Display2 (external).
The video setup does have Xinerama disabled in /etc/X11/xorg.conf.
When Xinerama is enabled, all seems to work well.

How to reproduce:

Open a presentation.

Configure the presentation settings to use "Display2 (external)".

Start the presentation.

Display1 now shows the presentation control screen, while Display2 shows a white screen. When "exchange" is done, Display1 shows the presentation but Display2 remains white.

When the presentation settings are changed to use "Display1" the results are similar, Display2 always shows a white screen.

System details: Fedora 17, x86_64, all updates as of today.
NVidia GeForce 7600 GS graphics card.
X.Org X Server 1.12.4 + nouveau driver 0.0.16.
LibreOffice beta1 (earlier versions of LO crashed in this setup due to bug #56583.
Comment 1 Johan Vromans 2013-06-23 19:35:18 UTC
The problem is still present in 4.1 RC1 and an absolute show stopper.
Comment 2 Jean-Baptiste Faure 2013-07-01 05:18:39 UTC
Please could you provide the following informations:
- the window manager you are using (Gnome, KDE, Xfce, other ?)
- did you try to disable Presenter Console in LO 4.1 (new option)? If you did, does it work? (so is the problem in Presenter Console or somewhere else?).

Side note: I have similar problem under Xubuntu 13.04 (Xfce window manager) but not with Gnome-shell or Unity. In my case the problem is in the window manager which does not manage correctly the second screen.

Thank you very much. JBF

I use Fedora 17 with Gnome2 with OpenBox window manager.
As for the presentation console, I haven't been able to locate this setting. Where should it be?
Comment 4 Johan Vromans 2013-08-30 07:07:37 UTC
I switched to the metacity (Gnome standard) window manager, but it makes no difference.

In LibreOffice 4.1.2 : Menu Tools > Options > LibreOffice Impress > General > checkbox "Enable Presenter Console" in group Presentation

Enabling/disabling the presenter console does not solve it. As soon as the second screen is involved it becomes, and stays, blank until I terminate the presentation.

Comment 12 tommy27 2016-12-21 16:05:37 UTC
the reported sent me an email telling this:

"I don't use Xinerama setup anymore so I cannot confirm either.

(I've mostly given up on OOo, I can't get into the bugzilla anymore).

so I close this report as INSUFFICIENT DATA.
