x.org configuration

Hi, I installed the new SuSE10Eval in my computer, setting vnc to work. All works ok, apart of USB2.0 pen drive that is slower than a floppy. After some updates (I think the nvidia official) no mouse nor keyboard works anymore in X mode. Going in to text mode I was disabled vnc, then mouse and keyboard works again. Somebody knows about it? And about USB pendrive? Thank you Thadeu
