Description Horst Schirmeier 2019-04-25 13:39:25 UTC
In LO's Impress, starting the slide show with a second screen attached shows the presenter console on screen #1, but doesn't display anything on screen #2 (unchanged, desktop background still visible).  With LO this works as expected (slide shown on screen #2).  Also reproducible with soffice --safe-mode.

Steps to Reproduce:
Environment: Ubuntu 18.04.2 LTS (amd64), KDE 5 with Plasma 5.12.7 (as shipped with Ubuntu), LO "Linux x86_64 (deb)" from, primary screen 2560x1440, secondary screen 1920x1200 extending the desktop rightwards (reproducible with other screens / resolutions).

1. Attach secondary screen, configure to extend the desktop to the right (e.g. using xrandr, arandr, ...).
2. Run soffice
3. On start screen: Create: Impress Presentation.  Pick arbitrary template.  Open.
4. Start presentation with F5.

Actual Results:
Primary screen shows presenter console (current slide, next slide, notes).  Secondary screen doesn't show current slide but continues displaying desktop background.

Expected Results:
Presenter console on primary screen, current slide on secondary screen.

Reproducible: Always

User Profile Reset: Yes

Side note: Disabling "hardware acceleration" doesn't change the observations described.

Thank you for your bug report.

This seems to be the issue already described in bug 119719, so I'm marking it as a duplicate. The underlying problem has been fixed in Qt 5.10, so outside of LibreOffice itself. Ubuntu 18.04 only has Qt version 5.9.5.
Should your problem still be reproducible with a newer Qt version, please reopen this bug report.
