posting the /var/log/Xorg.0.log would be helpful. from what you're
telling it seems
that you don't have hw video acceleration enabled and you're using the cpu to
accelerate your xorg. you've most likely not using dri for some sort
of error while
loading it or you have some kde4 effects that consume the cpu. in this
case also the
list of kwin effects would be useful.
from the log and the list of kwin4 effects we might be able to give
you more help.
also, if you're using radeon then you'd want to really use exa instead
of xaa since
it's more perfomant than xaa.
