I compiled and installed KDE 5 (Frameworks 5.28.0 and Plasma 5.8.4) from scratch succesfuly, but after the SDDM login, there's only a black screen with a cursor.

If I start xterm from the console, it appears. What's interesting is that I can start fine KDE 4 from the SDDM (only KDE 5 shows this problem, so my conclusion is that the X and graphics setup are fine). I tried to run plasmashell from the console and nothing happens:

Here's the log:

Any hints? Thanks!

Forget it! There're some missing dependencies like kactivitymanagerd and the usual QT variables which must be set:
