Apache OpenOffice (AOO) Bugzilla – Issue 119327
Cannot select presentation display with multiple displays
Last modified: 2017-05-20 10:32:04 UTC
On Linux, with a multiple displays set up, the multiple displays are not recognized and the presentation display cannot be set. To reproduce: * connect a monitor to the laptop, set the laptop display as the primary display * open Apache OpenOffice: while OOo 3.3.0 opens on the primary display, AOO opens on the secondary display * create a presentation * go to the Menu "Slide Show" -> "Slide Show Settings..." -> "Slide Show" dialog Under "Multiple displays", "Presentation display" is grayed out, the listbox is disabled. On OOo 3.3.0 you can choose the presentation display: - Display 1 (Primary) - Display 2 - All displays Note: bug on OOo 3.3.0, selecting "All displays" does not show the presentation on all displays, only the primary.

Created attachment 77527 [details] AOO 3.4: slide show running The slide show isn't displayed on the secondary display (top of the picture). It seems to be running on the primary display but taking the width of the secondary display. The slide show content is displayed with a vertical and horizontal offset.

I am currently setting up a machine on which I can reproduce this. Once this is done, I hope that I can fix this without the help of the old VCL team.
I can repdroduce this now (Ubuntu 12.04, 64Bit), although in a slightly different flavor: both monitors are apparently handled as one display, splash screen is displayed in the center and therefore being half on one and half on the other monitor. The slide show is displayed similar, centered on both monitors with wide black frames on its left and right side. I hope that it is even possible to get information about the underlying monitor geometries and that not only the virtual display is reported to VCL.
After playing arround with the multi-screen system settings for my ATI card I found out that: - when xinerama is activated then VCL does not/can not detect that the virtual display really is two displays. The result is as described in my lst comment. Strangely enough, in X11SalFrame::ShowFullScreen (in main/vcl/generic/window/salframe.cxx:2195) the test for detecting xinerama fails. - when xinerama is deactivated then the presentation can be run on either screen. The presenter screen is displayed on the other, respectively. All as expected. Only the "All displays" option is missing (but anyway, I can not drag any window onto the second screen; probably an error in the system configuration) @Arial, all: Can you tell me about your graphics system configuration (xinerama, randr, graphics card type, etc)?
I have found out what has changed. The Xinerama initialization in vcl/unx/generic/app/saldisp.cxx is not executed properly because the Xinerama environment variables are not set up anymore. The reason for that is the transition from dmake to gbuild. The code for setting up the variables was in the makefile.mk besides saldisp.cxx. The makefile is gone and so is this code.
Created attachment 77554 [details] Add USE_XINARAMA flag to other xinerama flags. Some of the old logic was transferred, but not all. Re-added the USE_XINERAMA flag that guards most of the xinerama related code in saldisp.cxx.
Taking ownership.
Fixed in revision 1339170.
Created attachment 77555 [details] A better prepared patch.
(In reply to comment #14) > Created attachment 77555 [details] > A better prepared patch. The patch works: * go to the Menu "Slide Show" -> "Slide Show Settings..." -> "Slide Show" dialog Under "Multiple displays", "Presentation display", the listbox is enabled. * the Presenter Console extension works now
set release blocker flag for 3.4.1
merged fix from trunk into branch AOO34, revision 1346824
1)Presentation display listbox is enabled. - Display 1 (Primary) - Display 2 - All displays 2)After enable xinerama, Slides show can show on all displays. (make primary and secondary display as one) Verify pass on Ubuntu with AOO341 branch r1359641.
