Bug Description
This is not a bug report but more of feature request.
I cannot use any nvidia driver newer than 185.18.14 on my Sony Vaio AR520E with Nvidia 8400M GT. The symptoms are, screen flickering, artifacts, complete system freeze, etc. It turns out that this is a well known problem with the latest drivers, a lot of people experience it. The problem is hardware specific, not OS dependent. The fix for is to turn powermizer off by creating a file /etc/modprobe.
options nvidia NVreg_RegistryD
Since Karmic boots into graphical desktop by default, any user whose h/w is affected by this bug will not be able to get even a usable login prompt after installing the nvidia driver. The user may not even be able to fix the problem. In light of that, please consider changing the installer so that the user gets a choice of turning on powermizer with a warning that it may make the system unusable. There should also be a boot-time option to disable powermizer, if X does not stat properly. Or maybe it is better to turn off powermizer by default with a warning that turning it on may create problems.
Please consider turning the powermizer feature off, or make it optional.

I had the same problems within minutes or even before logging in (as described in the bug), for me the fix worked.
I had to boot up from a live cd and mount my drives manually to create the file.
