why asking this question here - what does trinity has to do with it? I guess the wayland topic needs to be discussed in devel list, but a friend uses KDE5 with QT5 and wayland and last time I had a look there he said wayland has X11 emulator, where you can run applications that does not support wayland perhaps this is what you want to know 

trinity has to do with it because when i attempt to install the application and its dependencies, it wants to delete muct of trinity, which is my desktop of choice. i am trying to learn if there is a way to preserve trinity and to install the application.
