This a little tip for you.
During a conference with our partner we stumbled across sharing the desktop with Skype on a Fedora 28 (that runs Wayland). The option to share the desktop didn’t appear when clicking on the + button.
Wrong version? Doesn’t Microsoft provide that feature in the Skype’s version for Linux? Do I need to buy a Windows’ pc? Nothing of this…!
The solution is really easy!
The option doesn’t appear only if you are running Wayland (as the title suggests!). Test that you are running Wayland with this:
If the result is wayland-0 you are running Wayland!
So, the solution is to disable Wayland!
How to do that?
It’s really easy.. Edit your /etc/gdm/custom.conf with your favourite editors (vim):
> vim /etc/gdm/custom.conf
and uncomment the option WaylandEnable=false (remove the initial #).
That’s all! Restart your gdm or the system and you will come back to run the old fashion Xorg.
And, yes, the magic “Share your desktop” option will magically appear on Skype!
