Help: wheel mouse problems using Ubuntu 6.06

[john]

Hi all,

I've rolled out two ltsp clusters at our school district, both using Ubuntu
6.06 LTS desktop. One serves 18 thin clients distributed over 4 buildings
via a vlan'd fiber backbone, the other server currently has 5 clients and
slated to grow to 18 as well. So far things are working well, however I have
a problem that I can't seem to resolve. The thin clients have optical wheel
mice and the wheels won't scroll at all.  Googling and Ubuntu forum searches
haven't solved this one for me. I DO know that this problem is fixed
in 6.10but I don't want to upgrade since I am like the idea of long
term support
(one of the reasons I moved away from k12LTSP is the blazing release cycle).

My servers running 6.06 lts desktop are running:
 x11-common 7.0.0-0ubuntu45

The relevant section of the xorg.conf page looks like:

Section "InputDevice"
        Identifier      "Configured Mouse"
        Driver          "mouse"
        Option          "CorePointer"
        Option          "Device"                "/dev/input/mice"
        Option          "Protocol"              "ExplorerPS/2"
        Option          "ZAxisMapping"          "4 5"
        Option          "Emulate3Buttons"       "true"
EndSection

In contrast, my workstation running 6.10, on which the optical wheel mouse
scrolls just fine is running:
1:7.1.1ubuntu6.2


The relevant section of the xorg.conf page looks like:

Section "InputDevice"
        Identifier      "Configured Mouse"
        Driver          "mouse"
        Option          "CorePointer"
        Option          "Device"                "/dev/input/mice"
        Option          "Protocol"              "ExplorerPS/2"
        Option          "ZAxisMapping"          "4 5"
        Option          "Emulate3Buttons"       "true"
EndSection

both computers are running the psmouse module

Anyway I hope someone can help me out.

Thanks!

John
