SlideShow displays on 2 screens in dual-head system

[Carl]

Binary package hint: openoffice.org

Linux Ubuntu 7.10, OpenOffice 2.3.0, Impress

When presenting a slideshow on my laptop, having the graphics configured for both my LCD display and the external VGA display (Xinerama mode), impress displays on both screens instead of just the screen it is currently on. That is, half of the slideshow is on my laptop display and the other half is on the projector. Note: Acrobat works just fine in its slideshow equivalent mode so it is not an OS issue.

Workaround:
For now, I changed the slideshow display properties to display in a window instead of full-screen mode. The window mode correctly displays on one screen. Down side is that it looks messy with the window border and a few other things displayed, but at least my customers can see it.

I can verify this issue.

Additionally: Slide Show->Slide Show Settings shows the "Multiple Monitors" section grayed out.

Another work-around is to use Sun's official Linux binaries--xinerama support works like it is supposed to.

[Tangentially: in the Unbuntu build, running with twinview rather than xinerama causes only one half of the presentation to be visible on a single screen. I don't know what the expected behavior is & haven't tried Sun's build yet.]

Since upstream works, I think Ubuntu's package may need to be fixed.

[karnesky (karnesky)]

I just tested & Sun's binaries also support twinview fine.

I continue to encounter this bug in Hardy+OO.o 2.4: Ubuntu's binaries don't work with twinview or xinerama, while the official Sun build does.

The old bug with half the presentation appearing on the right half of the screen only is still present in Hardy (clean install) on AMD64, with two 1600*1200 screens, and Nvidia 7600GT graphics card. also on Asus 7520 laptop with exterrnal TV or projector, again 64 bit but running Hardy beta. Both are Xinerama right now, Others are reporting it with Xinerama.

On the Asus, I have a slight problem, not related as far as I can see, because the 1440*900 screen defaults to 1024*768, same as the external projector. I think that is a limitation of the Nvidia 7000M and not part of this problem.

Can anyone suggest specific tests which would help to diagnose this problem?.

Meanwhile, I will try a few things myself and report back. This is a show-stopper for people who need to give presentations, so I am quite keen to provide as much input as possible.

This is a guess, but I would suspect that Impress, or the window manager (I am using Kubuntu, so KDE), is using the size of one screen to set the size of the window, but gets mixed up between physical screen centre and the centre of the overall X screen.

Oh, and as suggested elsewhere a while back, it is not openoffice.org-gtk, which is not installed.

More info:

On the Acer, it seems to work perfectly with seperate X screens (which is typically not very useful), but with TwinView, the slide show opens in the laptop, regardless of whether I start with Impress on one screen or the other. That may be fixable with the X config. But it is stall half the screen, always on the right, regardless of how the screens are set with respect to one another.
So what is common to Twinview and Xinerama? Therein probably lies the bug.

I will do some more tests, and be back later.

Do you still have this problem with Ubuntu 8.04 openoffice.org 1:2.4.1-1ubuntu2 that is in hardy-updates? There have been some fixes that sound like that might correct this problem as well.

Thanks,

Chris

Chris,

  No, it works just great! I really appreciate the feature to define
what screen it displays to. The only glitch is that, when presenting,
the "current page" does not move with the slide. Thus, when you exit
the SlideShow, you must move the current slide forward to match the one
you just finished presenting.

Thanks,
Carl L.

I can also confirm that this is fixed, so am closing.
