Using wheel mouse on Ubuntu on VMware

By default, you cannot use wheel of mouse on Ubuntu on VMware.
You should configure /etc/X11/xorg.conf.

First, check your mouse setting in /proc/bus/input/devices.

$ more /proc/bus/input/devices
.
.
I: Bus=0011 Vendor=0002 Product=0005 Version=0000
N: Name="ImPS/2 Generic Wheel Mouse"
P: Phys=isa0060/serio1/input0
S: Sysfs=/class/input/input3
H: Handlers=mouse1 event3 ts1
B: EV=7
B: KEY=70000 0 0 0 0 0 0 0 0
B: REL=103
Change your mouse "Driver" and "Device" in /etc/X11/xorg.conf
Original:
$ sudo vi /etc/X11/xorg.conf
.
.
Section "InputDevice"
       Identifier      "Configured Mouse"
       Driver          "mouse"
       Option          "CorePointer"
       Option          "Device"                "/dev/input/mice"
       Option          "Protocol"              "ps/2"
       Option          "ZAxisMapping"          "4 5"
       Option          "Emulate3Buttons"       "true"
EndSection

Change it like:
Section "InputDevice"
       Identifier      "Configured Mouse"
       Driver          "evdev"
       Option          "CorePointer"
       Option          "Device"                "/dev/input/event3"
       Option          "Protocol"              "ps/2"
       Option          "ZAxisMapping"          "4 5"
       Option          "Emulate3Buttons"       "true"
EndSection
Restart gdm and you can use wheel.
$ sudo /etc/init.d/gdm restart

    Actually, simply change the line in the conf file from

    Option "Protocol" "PS/2"

    to

    Option "Protocol" "IMPS/2"

    will do the job.

    Thank you so much for this post. The popular suggestion of using "ImPS/2" protocol does NOT work for me, but your method does!

    (I have a Logitech USB optical mouse, in case others are curious)

    Thanks a lot!!
    As Ben mentioned, the more popular methods of resolving this issue did not work for me.

    I knew it could be done, just didn't know where to put the hack!!!

    My situation is unique... I have a an old ball-mouse attached via PS/2 (needed for my KVM switch...) and a USB mouse. The PS2 mouse scroll worked, but the my primary USB mouse's scroll bar did not work!! What a headache.

    Thanks again.....
