I have a Nvidia GTX 275 on Mac OS X 10.5.2 Kalyway.

Before I installed the driver I would get a crappy 1280x900 resolution and big black boarders around the edge of my screen.

Now that I've installed them, if I try start up normally, I get a blank blue screen when the logon window should be appearing.

The only way I can get past this is by using -v -x flags before booting.
By using -v -x it gives me 1080p resolution but no 3D acceleration or Quartz Extreme.

Is there any way to fix this?

How and what driver did you install? We can try a fix for that series card found on Netkas' site but we will need to remove any driver you have previously installed before we can try these new one.

* Please do not continue until we have addressed the above
Here are the two posts which mention your series of graphics card. The first has a link to an installer.
