[neo_returned]

Hi everyone. I have installed kubuntu 8.04 and nvidia driver 180.77 on my amd geforce9800 gt system. But in the first boot, the windows has no borders and minimize, maximize close window buttons. After i logged out and restart x server, the windows optimizing and borders and buttons are coming. What is the probelm ? can anyone help ?
