Yes. But the active resolution is the one labeled "Auto".
Actually I can select 1600x1200 in nvidia-settings when
I start without an xorg.conf file; the only problem is that
the gnome applications still use font sizes that are intended
for the 1024x768 resolution, and are much too small now
after changing to 1600x1200 in nvidia settings.
screen #0:
dimensions: 1600x1200 pixels (616x455 millimeters)
resolution: 66x67 dots per inch
EDID data had a horizontal screen size of 390 mm or
390 mm / 25.4 == 15.354 inches. 1024 / 15.354 == 66.692 dpi
Correct would be 1600/(390/25.4) == 104.207 dpi
xdpyinfo is reporting 616 mm? Hmm, 1600 / (616 mm / 25.4) == 65.976 dpi

Ok, I generated (Xorg -configure) a default xorg.conf file, and
added Virtual 1600 1200 to the "Screen" -> "Display" sections.
Now the initial dtlogin screen displays a much larger 1600x1200 screen
at 1024x768 resolution; the mouse can be used to move around the
visible window. But during login to the gnome desktop the resolution changes
to 1600x1200. Inside the gnome desktop the fonts are too small.
