KDE Plasma without the need to install SDDM, help!

[teo]

KDE Plasma doesn't enter the desktop graphic without the heavy package of sddm , how can you proceed without installing that sddm package ?

If you mean launching KDE plasma with startx(1) for example, then set in ~/.xinitrc exec ck-launch-session startplasma-x11, as advised in the handbook. If you mean something else please return back.
