GNOME Bugzilla – Bug 795186
The b-button for blacking a slideshow does not work
Last modified: 2018-04-12 08:30:24 UTC
The b-botton is supposed to project a black screen when i slideshow mode. This function stopped working when I upgraded from Ubuntu 16.04 to 17.10, ending up with evince version 3.26.0.
The w-button works properly, and projects a white screen. Obviously, the ability to project a black screen is critical when the the video projector is projected on, e.g., a whiteboard during a lecture, when one alternates between writing on the board and using PDF projections.
Thanks for taking the time to report this.
