Am 16. Feb, 2019 schwätzte Brian Cluff so: moin moin Brian, Yeah, but can you setup two KDE workspaces to mirror? Workspace 0: normal desktop Workspace 1: presentation workspace 2: presentation Hmm, even without mirror, pin Hugin to two desktops. Have two dual desktop workspaces. ----- |0|1| <- workspace 0 ----- |2|3| <- workspace 1 ----- 0 and 1 are one workspace for presentation mode. 2 and 3 are the second workspace for demo mode. 0 gets LibreOffice notes for laptop screen. 1 gets LibreOffice presentation for external screen. 2 gets Hugin, pinned to 2 and 3, for laptop screen. 3 gets Hugin, pinned to 2 and 3, for external screen. Then during the presentation switch between the workspaces. Gonna have to experiment with this myself. ciao, der.hans > It's a laptop, so 2 ports on the same card.  Getting the notes on a separate > display isn't the problem.
