I'm looking for a way to turn off mouse pointer shadows under X.
There are a number of xconf options to do this when running with
Nvidia drivers. Does anyone have a method that [works] [with the]
ATI [X modules?]
Which X module are you using? I don't see any options like that in
my xorg.conf for the evil binary-only fglrx module, or the radeon X
module.
Yes, using a variant of this.

*Which* *one*? "This" is a vague pronoun reference here, and could
refer to fglrx or radeon. You need to be more specific than is common
in standard writing if you want to get tech questions answered well.
http://catb.org/~esr/faqs/smart-questions.html is snarky, but valuable.

Are you sure these "cursor shadows" aren't being done in software
through X cursor themes?
There is a a faint shadow on the cursor when the cursor in on the
mouse cursor when say over an xterm, when running without a window
manager.

The "redglass" and "whiteglass" cursor themes that are standard with
modern X have things that look suspiciously like shadows on them. If
your "pointer" cursor is white with a drop shadow, you're almost
certainly using whiteglass--the default pointer cursor is black with a
1-pixel white border. You find cursor themes in various places; "locate
\*whiteglass" will probably tell you where they are on your system.
Here, they're all in /usr/share/cursors/xorg-x11/ .

If you don't know which theme you're using, compile and run the
following snippet of C code:

/* No error checking, if it breaks, you get to keep both pieces.
* gcc -o xcursortest xcursortest.c -lX11 -lXcursor */

#include<stdio.h>
#include<X11/Xlib.h>
#include<X11/Xcursor/Xcursor.h>

int main(void)
{
Display *d;

d=XOpenDisplay(":0");
printf("Cursor theme is %s\n",XcursorGetTheme(d));
XCloseDisplay(d);
return 0;
}

/* end xcursortest.c */

Wait, what? Are you running without a window manager?
I'm providing an Xserver without a window manager, the client apps
including window managers are up to the end user.

This is really weird. What's going on here? I have a feeling you've
left a lot of details out of your problem.

The shadow around the cursor causes an issue because of colour keying
hardware

? I've never heard of anyone saying that cursor themes don't work with
XV-using apps like mplayer and xine. Or are you doing something weird
like running at 8-bit depth? Or is it a different kind of color keying?

Is the shadow around the cursor/pointer an aspect of the cursor theme?

I'd guess so, but ICBW. Run the C bit above and see what you get.

Thanks, info appreciated, this is a new area for me.

Yeah, I don't have any idea what you're doing here either. Oh well, the
code above will tell you at least some info.
