X won't start at boot with NVidia driver

[Ed Jabbour]

Running kubuntu 7.10 on an HP laptop.  I downloaded the proper driver from the 
Nvidia site and it installed with no error messages.  I ran startx and no 
problems.  However, at a reboot, X would not start - screen not found.  I 
edited xorg.conf to load the vesa driver and got X.  The NVidia driver will 
not run correctly until I delete a number of libnvidia .so files and a few 
others from the /usr/lib directory.  It then installs and startx works, but 
not at reboot.  The same process over and over.  

Any hints, pointers, etc appreciated.
