Hm, but if you do not renice X, it works ok?

I just noticed:

So if you add X and kde (and other heavy stuff to that), you basically have no RAM,
so probably all the slowdown is from constant swapping.
Just run top when you see the interactive slowdown and look at the swapin/swapout ratio
and swap isage in top & /proc/stat
