Linux - las x con un usuario kde

hola buenas,mi duda es la siguiente:
se me arranca kubuntu normal y cuando aparece la ventana para acceder al sistema pongo mi nombre de usuario y mi contraseña
le doy se me queda un rato esperando y se me vuelve a cargar esa misma ventana y no se me inicia kde.

si me voy a consola puedo entrar en la cuenta de usuario pero cuando startx me da errores y avisos
sin embargo como root si puedo entrar en kde

alguna idea??


concretamente me pasa esto:
