when i for instance run kodi, when i switch to full screen it defaults to hdmi-0. how can i get kodi to run fullscreen on dp-3?

[CwF]

Does Kodi itself have a command line switch?

Mpv does, for example when I watch TV on my homebrew poorman kodi

Code: Select all

mpv dvb://7.0 (--dvbin-full-transponder) --screen=1 --cache=yes --cache-backbuffer=500000

screen 0 is the primary... and full transponder isn't fully working for me yet...

tbh i don't know

but i happened to use kodi whereas it is not he only app where i need this solution

there is surely an os wide way of dealing with this?

Not really. If not baked in to the executable then there are to many angles to solve for. Some DE's offer some positioning, and there are some packages to modify launchers, I can't remember the few I tried. Nothing really works well for dynamic conditions other than the executable itself.

Check kodi doc's, I'd think it would have it?

thanks for that link. it's interesting. got it work with a number of apps.

but neither works for kodi or iptv smarters which are my issues.

as an aside it is strange how xtream codes api seems to be largely ignored in linux generally.
