Nvidia 8600 graphic card cant be used after automatic Ubuntu update

[oddvar]

After automatic(!) update of Ubuntu 9.10 Dec 6 2009 my computer only run in low graphic mode. None of the options I have in GUI startup/login can fix this error. For me this is the worst Ubuntu error i have ever experienced. My graphic card is NVidia gforce 8x00 (i think gforce 8600)
The computer did work well until automatic update, and none of the possible solutions I find about resetting graphic to older version or nvidia-xconfig can correct this error

My graphic card is Nvidia gforce 8500GT.
I installed earlier NVIDIA-Linux-x86-190.42-pkg1.run because there were some errors with advanced use of desktop effects.
I have now made to start the computer with no hardware drivers for my screen.
Computer now runs well but, none graphics drivers are in use.

This bug report was filed against an old version of Ubuntu.
Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.
