[XFree86] Xinerma and Mouse Pointer

2005-08-10 Thread DOLLOFF, MATTHEW D. (MATT) (JSC-ER7) (NASA) 








I am currently trying to run 4 touch screen monitors using
Xinerama and am encountering a few problems. First of all, each monitor has
it's own graphics card and is up and running Xinerama without any problems.
The problem occurs when I try to use the touch capabilities. Every screen
either a) sends the pointer to the first screen (when I don't specify a screen
number in the touch portion of the elo driver) or only works when I first put
the pointer on that screen using the mouse (when I do specify a screen number
for each device). I am trying to figure out how Xinerama deals with pointers so
that I can get the pointer to move to the correct screen. 



Thanks,

Matt Dolloff

   The high level pointer code doesn't know about Xinerama.
It operates in single logical screen space and assumes it's
moving a cursor over the logical screen with input independent
of the screens (like from a mouse).  To make touch screen drivers
Xinerama aware, they would probably need to report their motion
relative to the logical screen.  I suppose that might look
something like:


#ifdef PANORAMIX
   if(!noPanoramiXExtension) {
/* given x,y on screen n, translate to the logical coordinate */
  x += panoramiXdataPtr[n].x;
  y += panoramiXdataPtr[n].y;
   }
#endif

  This is just a guess though.  I haven't studied this.

Sorry of my ignorance on this, but I new to this stuff.  How do I get the
panoramix data into the elo driver (xf86elo.c)?It seems as if there
should be some easy way to do this.

Thanks,
Matt
