Probably some of the gurus here knows better, but I'm afraid that the X Window
System doesn't allow changing the resolution or the bit depth of the root window.

I am not trying to change resolution or bit depth, I am trying to turn
off a feature. You could change the resolution manually with a utility
like xrandr. Also you can change the bit depth when you start X windows
up with a command such as startx -- -bpp 16.

I must not have stated my problem correctly, I apologize. What I want
to do is be able to switch modes with the sequence
and not have a virtual resolution of 1024x768 while in the 800x600 or
640x480 mode. When you do this you have a virtual desktop of the
highest resolution on your Modes line. The screen pans wherever the
mouse goes.
I would like to turn this off, but I cannot find anyway to do this
other than just specifying one mode on the line by itself.

For example: Modes "800x600"

I don't want to do this, because I will not have the convenience of
cycling through modes with the aforementioned key sequence.

Isn't there some way to do this? Any help would certainly be appreciated.

That's equivalent to changing the resolution of the root window dynamically (which
is what I was referring to in my previous answer). I think you can't do that in
the X Window System - if you start it in 1024x768, the root window will always be
that resolution, even if you change the screen's resolution - that's why you can
pan the viewing area with the mouse. If you disable panning, then some part of the
screen real estate will become unavailable.
Idem for bit depth, you can't change the 'desktop' bit depth once the system is
initialised (but you can have windows with different bit depth simultaneously on
the screen in some systems like Suns, SGIs, HPs or some gfx cards on PCs, like
Matrox).
You can, however, have a 'true' resolution/bit depth change if using a
non-standard extension in XFree86's X servers, called DGA 2.0, but that's mostly
useful for games. Maybe that will be suitable for your application, but it won't
work with X servers from other brands.
Anyway, take this with a grain of salt - I'm not an X expert, just speaking out
of experience.

kde, in last versions, do it.

It can change real resolution and change virtual resolucion in kcontrol
(like hasecorp).

XFree86 4.3 might fix that, from what I've heard. I don't have 4.3
so can't say for sure. I would hope 4.3 also allows for the changing
of pixel resolution without a virtual scrolling screenport. Of
course everything will have to resize/refresh, which suggests an
extension handled by the window manager.
