[ltp] Re: Trackpoint going haywire under 2.6

[Dimitris Kogias]

I also have a X31, running 2.6.2 from kernel.org.  I have exactly the
same symptoms the previous posters mentioned:  Occasionally the
trackpoint goes crazy for 1-2 seconds and at the same time, this gets
logged:

Feb  5 00:52:31 0x19 kernel: psmouse.c: Mouse at isa0060/serio1/input0
lost synchronization, throwing 2 bytes away.

2.6.1 with an indentical .config ran without any problems.  I also
briefly tried 2.6.2-rc3 and it exhibited the same problems that 2.6.2 
has.  Haven't tried any -mm kernels yet but based on what I've seen here 
it may be worth a try.

XF86Config-4 pointer section:

Section "InputDevice"
         Identifier      "Configured Mouse"
         Driver          "mouse"
         Option          "CorePointer"
         Option          "Device"                "/dev/psaux"
         Option          "Protocol"              "PS/2"
         Option          "Emulate3Buttons"       "true"

         Option          "EmulateWheel"          "true"
         Option          "EmulateWheelButton"    "2"

         Option          "Emulate3Buttons"       "true"
         Option          "ZAxisMapping"          "4 5"
         Option          "EmulateWheel"          "true"
         Option          "EmulateWheelButton"    "2"
EndSection
 

...

Section "ServerLayout"
         Identifier      "Default Layout"
         Screen          "Default Screen"
         InputDevice     "Generic Keyboard"
         InputDevice     "Configured Mouse"
EndSection
