I am running kde on debian jessie (X11+Gnu+Linux). When doing a presentation, using LibreOffice (OpenOffice) presenter, the audience sees the external display, and I see the presentation console on the internal display.
I then with to use the laptop to do some thing else, while continuing to display a slide for several minutes. I was hopping to freeze the external display, and do the other things on my laptop.
Is there a way to do this?, command line is good. Other solutions specific to LibreOffice/OpenOffice, will also be accepted.
I am teaching a lesson to pupils. I have displayed a starter activity, and wish to do register, while they get on with this activity. They need to be able to refer back to this slide at any time during activity.
I have tried searching, but all I find is “help my xxx has frozen …” I can not see anything in xrandr (and gui wrappers such as kscreen), am I missing something?
