Remote desktop problems

Well, I have 4 monitors on 3 cards and for some reason desktop sharing doesn't work right. At first is would let me log in but when I moved the mouse it would only track vertically not horizontally. So I thought that if I updated to the very latest one it would work better. Well, it didn't. Now it crashes and I can't tell why.

So, I thought maybe I should try NX. So, I installed freeNX and knx since I am running kde. Well, it seems to work great but I can not figure out how to get NX to work for desktop sharing with krfb. Seems like it would be staight forward but I have no idea where to start.
