I've installed teams on Fedora 30 and I use the i3 desktop environment. , appears to be the same in another admins Ubuntu desktop, i3 also, both x11 not wayland
Unable to share my screen with windows or other Linux(Ubuntu) desktops.
I have the option to share, and have a black bar at the top when i do, it only state Connecting, and also has a stop presenting button. after a minute or so it stops the share itself.
This maybe a network problem, but i'm unsure the destination and ports needed.
EDIT****
I've tried Fedora 30 Gnome DE, and it had the same issue. not able to screen share. same connecting time out.
The unofficial ms client was able to screen share, it was a bit clunky, so not something i want to use.
