Re: Turning off mouse shadows in X Xorg 6.8 on Ati M9 hardware

Well on further investigation I'd misread/misunderstood where the alpha
blending associated with the mouse pointer icon originated. The shadow
being defined in the font itself, rather than as a function of a
Xserver/Window manager interaction as in the drop shadow around a
window.

Thanks for the pointers

Thanks for the reply, I'll clarify.

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.

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.

This needs to be a startup configuration setting (not one using a
window manager).

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.

The shadow around the cursor causes an issue because of colour keying
hardware and it would be desirable to effectively turn this off by
default.
There appear to be compile time options, but I'd like to avoid this.

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

So it could be removed by selecting a different default cursor setup
for the Xserver build?

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

Usually, you
don't *do* that, unless you've got some sort of kiosk app running. If
you have a kiosk setup, you generally just start X and have .xinitrc
start the appropriate application. There's no room for anything other
than the app and X there; you just put whatever config you need in
xorg.conf or xinitrc. Thing is, I don't know of any standard X
commands to manipulate cursor themes from the command line. There
are obviously ways to set them programmatically, and "man Xcursor"
talks about various file paths that X searches for cursor themes, so you
may be able to hack something together with that info.

I [would] rather avoid having to have two different [versions] of an
X [config file], just to support shadow-less mouse pointers.

Please try to answer the questions posed in the paragraphs above, and
maybe someone will be able to help you. There's not quite enough data
for me to make a complete diagnosis yet. HTH anyway,
