X11 will ask for twm if there is no other Window Manager available, or a 
Display Environment not configured.

Have you sorted out your ~/.xinitrc, or have you added your startup command in 
/etc/env.d/90xsession?  

There used to be a time when you could drop in your startup command in /etc/
X11/Sessions/, but I think this is no longer used.

You should spend sometime reading:

In Plasma this would be kwin, which acts as a window manager and a compositor.  
If you had installed Plasma in accordance with the URL I shared in previous 
emails you shouldn't have this problem, because from what I recall kwin is 
being drawn in as a dependency of Plasma.

Heh!  Yes, you can't expect a DE to work if major packages are missing.  ;-)

It is not in the Handbook, which has the purpose of installing the Gentoo OS 
itself, but it is in the Gentoo Documentation - look at the dropdown menu 
'Documentation' of the Handbook web pages:

https://wiki.gentoo.org/wiki/Category:Desktop

In your case, as I posted previously, you need:

https://wiki.gentoo.org/wiki/KDE

But, from the errors you've been getting with startx it seems you haven't read 
relevant Xorg documentation either.

For SDDM you better read this first:

https://wiki.gentoo.org/wiki/SDDM

Glad you got your desktop going!  :-)
