That's what I'm doing now, but it's a pretty bad user experience and definitely isn't seamless. Also completely breaks any integration with my app menu meaning I have to rewrite all the desktop files to launch the app in cage. I imagine someone will eventually make a seamless wayland compositor for x though.
>That plus existing solutions for Wayland network transparency should be enough.
If you're saying it will fix my x2x use case, well it won't. Wayland's security model fundamentally prevents this use case. Maybe someone will add extensions to it eventually but right now the way compositors handle mouse capture seriously prevents this use case, and I'm skeptical that all the different compositors will agree on a solution any time in the next 10 years...
So I'm stuck using X on both displays for the foreseeable future if I want to use x2x/synergy like functionality, and I'm certain that it's going to become harder and harder to keep using X over time...
Wow and here I was hopeful that Wayland would actually make this kind of thing easier. I'm a big fan of synergy and all it's descendant. Apple just released a similar feature for iOS and OSX. Really surprised this is getting more difficult on Linux instead of easier.
