Problem with GDM and mouse wheel

[Johan Bilien <jobi coruscant lappis org>]

Hi,

I have a very strange problem on my Linux Debian (Sid) box. When I use
GDM, everything is OK except that my mouse wheel won't work any longer.
I had this problem with GDM 2.2, and still have it with GDM 2.4
(unofficial debian package).

My mouse is a Microsoft Intellimouse Explorer (with 5 buttons), and I
use those settings with X:

---
Section "InputDevice"

# Identifier and driver

    Identifier  "Mouse1"
    Driver      "mouse"
    Option "Protocol"    "ExplorerPS/2"
    Option "Device"      "/dev/psaux"
    Option "Buttons"     "7" 
    Option "ZaxisMapping" "4 5"
    Option "Resolution" "200"
---

Those settings work fine with no GDM (starting X with startx). Here is
an extract from my XFree86.0.log:

---
(**) Option "Protocol" "ExplorerPS/2"
(**) Mouse1: Protocol: "ExplorerPS/2"
(**) Option "CorePointer"
(**) Mouse1: Core Pointer
(**) Option "Device" "/dev/psaux"
(**) Option "Buttons" "7"
(**) Option "ZAxisMapping" "4 5"
(**) Mouse1: ZAxisMapping: buttons 4 and 5
(**) Mouse1: Buttons: 7
(**) Option "Resolution" "200"
(**) Mouse1: Resolution: 200
---

There doesn't seem to be any problem. Still my wheel isn't recognized any
longer by my applications as soon as I use GDM.

Thank you,
