Hi, Just added a Microsoft Laser Mouse 5000 to my pc and am now having this issue also...however I believe I may have found the cause (although I've only investigated briefly).
Having downloaded the xserver-xorg-input-evdev-udeb source package (http://packages.ubuntu.com/precise/xserver-xorg-input-evdev-udeb) the changelog contains mentions of merging a smooth scrolling branch on Wed Nov 9 16:01:48 2011 +1000. evdev.c contains conditionally compiled code depending on whether smooth scrolling should be enabled as to how it handles the scrollwheels. Either: In EvdevProcessRelativeMotionEvent we have: #ifndef HAVE_SMOOTH_SCROLLING case REL_WHEEL: if (value > 0) EvdevQueueButtonClicks(pInfo, wheel_up_button, value); else if (value < 0) EvdevQueueButtonClicks(pInfo, wheel_down_button, -value); break; case REL_DIAL: case REL_HWHEEL: if (value > 0) EvdevQueueButtonClicks(pInfo, wheel_right_button, value); else if (value < 0) EvdevQueueButtonClicks(pInfo, wheel_left_button, -value); break; /* We don't post wheel events as axis motion. */ #endif Or: In EvdevAddRelValuatorClass: #ifdef HAVE_SMOOTH_SCROLLING if (axis == REL_WHEEL) SetScrollValuator(device, axnum, SCROLL_TYPE_VERTICAL, -1.0, SCROLL_FLAG_PREFERRED); else if (axis == REL_DIAL) SetScrollValuator(device, axnum, SCROLL_TYPE_VERTICAL, -1.0, SCROLL_FLAG_NONE); else if (axis == REL_HWHEEL) SetScrollValuator(device, axnum, SCROLL_TYPE_HORIZONTAL, -1.0, SCROLL_FLAG_NONE); #endif Before smooth scrolling, REL_WHEEL was mapped to vertical scrolling and REL_DIAL and REL_HWHEEL were mapped to horizontal scrolling. After smooth scrolling REL_WHEEL and REL_DIAL are mapped to verical scrolling and REL_HWHEEL is mapped to horizontal. Fixed for me by changing the REL_DIAL axis to SCROLL_TYPE_HORIZONTAL. I've attached a patch for the source which solved it for me. Suppose alternatively you could just remove the HAVE_SMOOTH_SCROLLING definition.
