I can confirm this issue remains with Ubuntu 14.04.3 LTS. Mouse is a Microsoft Wireless Laser Mouse 5000 v1.0
Running xev confirms mouse wheel tilt right and left (buttons 6,7) are being remapped to mouse wheel scroll up and down (buttons 4,5). version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.8.2-1ubuntu2 Bug Report filed: Bug #1508475 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-input-evdev in Ubuntu. https://bugs.launchpad.net/bugs/926917 Title: Mouse wheel tilt not works Status in xserver-xorg-input-evdev package in Ubuntu: Incomplete Bug description: Ubuntu 12.04After updating the xserver-xorg-input-evdev package from 2.6.0-1ubuntu13 to 2.6.99.901-1ubuntu3 the Microsoft Wireless Laser Mouse 8000 wheel tilt works like scrolling and the xev utility reports that buttons 4 and 5 clicked when I try to tilt the wheel left and right (should report 6 and 7 buttons for the tilt, 4 and 5 for wheel scroll).
