Are you sure you installed xserver*?
Maybe one of the packages is simply missing from their repositories.
Yes, this time (I made that mistake with Void Linux) I double-checked myself and it is installed.
X starts but is just stalling, will boot it up and post the message in a sec, have to SSH in whilst watching StarTrek Discovery

Second longer part in the TXT file is my Xorg logfile, Xserver starts but then stops.
SDDM also doesn't , when started after booting it shows no username nor any keyboard or mouse entry possible.
