nvidia driver don't work for me

Hello sorry if this is a repeat post, my previous podt did not do thru ! I have a HP zv5000 laptop with WUXGA (1920x1200 - GeForce 440 Go 64) LCD display. My problem is that I cannot get the latest nvidia drivers to work. After installing the driver, vertical lines appear on the screen :-( . Even old drivers don't work. I'm using SUSE9.1 64 version(AMD64). Have tried with FC3 also, still no luck. I have followed all the steps mention in various forums on the net, but the dam drivers don't work. I'm now wondering if the nvidia drivers support WUXGA ? Did anybody on this forum have any such problem ? -t
