My thought is: Xconfigurator sucks :-) When I first installed linux it gave me
a deeply crappy XF86Config. I ended up reading the vide timings HOWTO
and hacking out a custom mode. But I don't think you need to do anything
like that :-)

Just to edit your /etc/X11/XF86Config to select the resolution and depth you
want. Here is the relevant section of mine (right at the end)
----
# The accelerated servers (S3, Mach32, Mach8, 8514, P9000, AGX, W32, Mach64
# I128, and S3V)
Section Screen
Driver accel
Device My Video Card
Monitor My Monitor
Subsection Display
Depth 16
Modes 880x660
# Modes 1024x768
ViewPort 0 0
EndSubsection
EndSection
----

So you can see that I have selected colour depth 16 and a slightly weird
resolution of 880x660. You need to edit these two lines in your file to put
the values you want.

If Xconfigurator is spitting the dummy it's worth checking that the file has
the correct vertical and horizontal refresh rates for your monitor. Again
here's the relevant section of mine

-----
HorizSync 31.0 - 82.0

# VertRefresh is in Hz unless units are specified.
# VertRefresh may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY. REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.

VertRefresh 50-90

Danger Will Robinson! Put the correct values for your monitor in here not the
ones I am using.
