System Stalled and Now Cannot Start Desktop

Running 13.2 with KDE desktop and was in process of setting up an NFS share as a client using Yast. Sadly the system froze and nothing worked so I had to do a Alt+Sys rq REISUB to reboot. When system started up again it went to console. After logging in I tried to start desktop with startx and this failed. I have a message on the machine which I shall try and copy as follows:–

xinit failed. /usr/bin/Xorg is not set setuid, maybe that's the reason?
If so either use a display manager (strongly recommended) or adjust /etc/permissions/.local 
and run "chkstat --system --set" afterwards

Grateful for some guidance please before I mess up system more!!!

Do:

rpm -a --setugids --setperms

then do:

chkstat --system

This will check & reset systems permissions in system mode to what is set in /etc/permissions/security
