XFCE desktop on XQuartz ?

[henry]

Hi


I switched from a Linux-PC to a MacOS Mojave laptop.
So now I wish to switch from my old Linux Desktop to a brand-new full-screen desktop running on  MacOSX/XQuartz.
The reason is that I need a REAL unix-like desktop when I am at work (I am an engineer, I work on remote machines via ssh + Xterminal + remote programs written in Motif/QT)

I successfully installed KDE 4 with Macports, but unfortunately you cannot use it in this way (I confirmed it with the maintainer): the KDE desktop, I mean the KDE Windows Manager, has not been ported to work in XQuartz: you can just open several standalone applications (KTerminal, Konqueror and so on) but only on the Mac Desktop: you can have Apple Mail and KMail in the same window -- I couldn't care less :(

So I installed XFCE with Macports. The installation finished successfully.
Do you have any idea if I can start a XFCE desktop on XQuartz ?
I added:
exec startxfce
to my .xinitrc, like I did on Linux, but XQuartz refuses to start ...
I am afraid it's incompatible, too ...


Is there anyone using XFCE as a "Linux/Unix-like full screen desktop" on Mojave ?


Thanks,
Henry
