>Description:
Hi,

I have a dell latitude D600. Some time my touchpad hangs for one or two seconds and when it comes back, I loose every notion of `acceleration' I add before.. 

It s like moving one point on the touchpad moves of 1 pixel on the screen which is ver boring (actually not useable anymore : I have to use the TrackPoint instead. I don't know if there is changes for that one it is more difficult to tell.)

I have another mouse plugged in, an usb belkin with a wheel button. That one still works fine.

The values in xset remains the same before and after :

 Pointer Control:
  acceleration:  2/1    threshold:  4

and anyway restarting x doesn't change any thing. so doesn't soft reboot (kill 1 , exit single user.) The only thing I can do to get out of that hell of slowness is to reboot my beloved computer.

I don't know what to track.. so I wrote a little thing to dump value from psm:
I get the same value before and after it happens


protocol : 7
rate : -1
resolution : -1
accelfactor : 0
level : 0
packetsize : 3
syncmask [192][0]

(here is the program.. maybe there is no needs for it and there is already an tool to do that but I couldn't find it

#include <sys/ioctl.h>

#define psm_path "/dev/psm0"

int
main(int argc, char *argv[])
{
  int psm = open("/dev/psm0", O_RDONLY);

  mousemode_t mode;

  int res = ioctl( psm, MOUSE_GETMODE, &mode );

  if ( -1 == res )
      return 1;

#define print(P)        \
  printf( "%s : %d\n", #P, mode.P)

  print(protocol);
  print(rate);
  print(resolution);
  print(accelfactor);
  print(level);
  print(packetsize);

  printf("syncmask [%d][%d]\n", mode.syncmask[0], mode.syncmask[1]);

)



I rebuild with the Freeb with 
device          psm             # PS/2 mouse
options         PSM_DEBUG=2
options         KBDIO_DEBUG=2

So I can show you a (maybe?) relevant dmesg output :

I would like so much somebody to help me that I even add my xorg.conf, although I guess it is useless, isn't it ?

Go bsd guys ! 

I honestly which I could help more, I have been through all the code and all, but it seems that it will be easier for somebody who knows.. However, if somebody has any clue of where to look at, especially why, having the same xset and the same ioct result, I don't have the same behavior of my touchpad..

could it be a problem from the hardware device itself ? then what to do about it ?

thanks in advance.
