suena a que no esta cargando la aceleracion de nvidia.

Con respecto a los 32-bits, cuando usas Depth 24 hasta donde entendi
estarias en 32-bit color. Cuando me pase a ubuntu tuve el mismo tipo de
dudas.
El readme de nvidia es muy completo y explica todo con detalle. Depende la
version de nvidia: /usr/share/doc/nvidia-177-kernel-source/README.txt.gz
Esto es lo que dice con respecto al tema Depth:

19A. DEPTH, BITS PER PIXEL, AND PITCH

While not directly a concern when programming modes, the bits used per pixel
is an issue when considering the maximum programmable resolution; for this
reason, it is worthwhile to address the confusion surrounding the terms
"depth" and "bits per pixel". Depth is how many bits of data are stored per
pixel. Supported depths are 8, 15, 16, and 24. Most video hardware, however,
stores pixel data in sizes of 8, 16, or 32 bits; this is the amount of
memory
allocated per pixel. When you specify your depth, X selects the bits per
pixel
(bpp) size in which to store the data. Below is a table of what bpp is used
for each possible depth:

    Depth                                 BPP
    ----------------------------------    ----------------------------------
    8                                     8
    15                                    16
    16                                    16
    24                                    32

Lastly, the "pitch" is how many bytes in the linear frame buffer there are
between one pixel's data, and the data of the pixel immediately below. You
can
think of this as the horizontal resolution multiplied by the bytes per pixel
(bits per pixel divided by 8). In practice, the pitch may be more than this
product due to alignment constraints.

En hardy(8.04) recomiendo envyng para obtener los ultimos drivers nvidia

en ibex(8.10) estoy usando nvidia 177

Bueno, espero que la informacion ayude y no te confunda :p
