- I could swear someone sent a patch to disable screen blanking on
MacOSX
by pushing a fake input event through a queue somewhere, but I can’t
find
it to save my life. Did I dream this, and/or is there a better way to
handle it?
I searched several lists at http://search.lists.apple.com/ and didn’t
come up with anything (some Classic-only technique on mac-games-dev and
unanswered question on cocoa-dev). My guess would be synthesizing an
event using the CGRemoteOperation API. Ah, eureka! The folks at #macdev
figured it out (again;-):

Looks like you want to call UpdateSystemActivity(UsrActivity)
- Calling SDL_SetVideoMode() with SDL_FULLSCREEN will leave a second
monitor on…is there some way to force this second display off? This
has
been generating a lot of “bug” reports in the ut2003 mac demo.
Originally, only the main display was captured. This was changed so
that by default, all displays are captured, but if you do
SDL_putenv(“SDL_SINGLEDISPLAY=1”), only the main display is captured.
If what you really mean is to put other displays in energy-saver mode,
I have no clue about that.
- Harmon Kardon’s USB SoundSticks seem to report as a joystick.
Looks like an error in the joystick code. We were trying to fix the
problem of keyboards and mice showing up as joysticks:
/* Filter device list to non-keyboard/mouse stuff */
if ( device->usagePage == kHIDPage_GenericDesktop &&
(device->usage == kHIDUsage_GD_Keyboard ||
device->usage == kHIDUsage_GD_Mouse)) {
/* release memory for the device */
HIDDisposeDevice (&device);
DisposePtr((Ptr)device);
continue;
}
What it should read is:
/* Filter device list to only joystick/gamepad stuff */
if ( device->usagePage == kHIDPage_GenericDesktop &&
(device->usage != kHIDUsage_GD_Joystick ||
device->usage != kHIDUsage_GD_Gamepad)) {
/* release memory for the device */
HIDDisposeDevice (&device);
DisposePtr((Ptr)device);
continue;
}
This will reject all non-gaming devices, but might give false negatives.
I think most devices report the joystick or gamepad usage, but some
might not.

I’m willing to patch all three if anyone’s got pointers on what to do.
