Running 9.10 on a system with nvidia graphics (7600 GS) here, and I've
noticed that the login screen runs at 1280x960 but pans up to a
1920x1080 screen, even though my default and preferred resolution is
1280x960.

I'm pretty sure this is because I have custom MetaModes specified in my
xorg.conf, and when X starts it looks for the "virtual" resolution of
the display, and the nvidia driver looks through the metamodes to
determine that, always assuming that a bigger dimension is preferred.
>From my /var/log/Xorg.0.log:

(II) NVIDIA(0): Virtual screen size determined to be 1920 x 1080

Once I've logged in, it goes to my actual preferred resolution, because
something further up the stack and after the login screen remembers my
settings.

I'm not sure if this explains all the cases reported in this bug, but it
might help.  How many of the reported cases here have nvidia graphics?
