Jumping mouse pointer - FC5

[Clodoaldo Neto]

In FC5, gnome desktop, the mouse pointer jumps randomly to one of the
screen borders at each minute or two when I'm moving it.  Tried with
two PS2 mouses and one USB mouse.

How could I investigate it further?

Just to let you know I've seen the same sort of thing since Red Hat
Linux 7.1.  It seems less worse, for me, with a USB mouse, and has
improved slightly over the years.

For some time, I've thought that there's something fundamentally wrong
with I/O issues, keyboards seem to have their problems, too.  I'll point
out that running Windows on the same hardware shows no problems,
whatsoever; and swapping mice and keyboards around doesn't fix the
problem, just alters the behaviours, somewhat.

and I thought it was me :) however I've only seen it since 7.3, no 
problems with any versions before that

Nor does running on slackware.

Are those optical mice, or older roller-ball mice?

Try <ctrl><alt><F1>.  Don't login or anything, but move your mouse
around.  Does it exhibit the same problem?  If not, it's probably
related to Xorg.  Try changing the protocol settings in your xorg.conf
(make a backup first!).   <ctrl><alt><F7> should return you to the
graphical login.

No

Changed the protocol from "IMPS/2" to "Auto" and the problem
persists:

Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "Protocol" "Auto"
#       Option      "Protocol" "IMPS/2"
        Option      "Device" "/dev/input/mice"
        Option      "ZAxisMapping" "4 5"
        Option      "Emulate3Buttons" "yes"
EndSection

I'm using a Logitech Click! optical USB PS/2 mouse via the PS/2 adapter
at the moment. Not FC5 but, maybe some help from the following xorg.conf
section?

Section "InputDevice"
  Driver       "mouse"
  Identifier   "Mouse[1]"
  Option       "Buttons" "9"
  Option       "Device" "/dev/input/mice"
  Option       "Name" "ImExPS/2 Logitech Explorer Mouse"
  Option       "Protocol" "explorerps/2"
  Option       "Vendor" "Sysp"
  Option       "ZAxisMapping" "4 5"
