Default Display doesn't show entire screen in 640x480 resolution

I'm using a Dell Inspiron 5150 with a GEForce2 Go 5200. My distro of Linux is Ubuntu Dapper, and I'm using the 2.6.15-27-686 kernel. I used to use nvidia's 1.0-7xxx (I'm not sure which exactly) driver and had no problems. Yesterday I updated to the 1.0-9746 driver (downloaded here: http://www.nvidia.com/object/linux_d..._1.0-9746.html) and since then I have not been able to get the 640x480 resolution to display properly. Only about 40% of the screen shows up on my display -- it's as if the screen is too big to fit on the display. 1024x768 and 800x600 work perfectly.

When upgrading my driver, I did not change my xorg.conf. Also, now even when changing the driver listed in xorg.conf to nv or vesa the 640x480 problem persists. My xorg.conf with the new driver looks like this:

If I change my xorg.conf to start X in 640x480 mode and run nvidia-bug-report.sh with logverbose 6 on, this is the log file I get:

http://web.mit.edu/minilek/Public/nvidia-bug-report.log

The version of X I'm using is 7.0.

Please let me know if you have any idea of what might be going on here.

Thanks,
Jelani

EDIT: I should note that I've tried commenting out the vertical and horizontal refresh rate lines in my xorg.conf. That did nothing.

This looks like a known bug. Try requesting "640x480_60" instead of "640x480"

Thanks,

Thanks, that fixed it. Now I have a very minor problem where two 640x480 options are available in my screen resolution menu with two different refresh rates (one works perfectly and the other has the same problem I mentioned above). My xorg.conf only has the "640x480_60" in it now though, so I'm not sure where the other option is coming from. This is a lot more minor since I can just pick the option that works, but I'm just curious where the other option is coming from.

Also, thanks for the speedy reply. This experience has given me even more evidence of nVidia's superiority over ATI (let's not talk about my extremely bad experiences with my desktop's ATI card).
