S I have an NVidia card in my laptop (Pangolin Panp4n, Intrepid 64 bit) and the refresh rate isn't synching with the system. If I goto my NVidia control panel, it says the refresh rate is on "Auto". Now when I goto to screen resolution in preferences, it says I have the choice of 50 or 51 hz. If I goto my NVidia control panel and set the refresh rate from auto to 60 hz, the only options I have now in my screen resolution preferences are 50, 51, and 78 hz. Shouldn't the two be consistent? How do I get them to match up? Compiz is a just a tad choppy and I would be this has something to do with it. Any thoughts?

I have a NVIDIA card running dual monitors on my desktop PC. This being said, I have never, ever bothered with the GNOME resolution preferences as I take care of this exclusively in nvidia-settings.

Long story short, I have never bothered to compare resolution between the two apps. So I guess the question is are you having resolution or visible refresh rate issues?

Is the image on your external monitor choppy? If so, this really has nothing to do with nVidia (I think). It's more likely that, if you, have a cheap monitor, Ubuntu isn't detecting it correctly, or is only making a guess at it. In these situations, it's often necessary to manually configure the monitor in xorg.conf.
