Val, thank you for providing the requested information. Given a solution was found through a modification in evdev, I'll reassign to it. This wouldn't be considered a duplicate of another bug at this point (ex. 926917) or vice versa as the other report doesn't have any log files for the original reporter, and the proposed patch hasn't been acknowledged by the OR to fix his problem.
The next step would be to engage evdev upstream in getting this reviewed for upstream inclusion by filing a report: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg Component: Input/evdev ** Package changed: linux (Ubuntu) => xserver-xorg-input-evdev (Ubuntu) ** Changed in: xserver-xorg-input-evdev (Ubuntu) Status: Incomplete => Triaged ** Summary changed: - 045e:00f9 [Gateway DX4860] Horizontal scrolling is broken with specific external mouse device + 045e:00f9 [Gateway DX4860] Horizontal scrolling is broken with 9-button Microsoft Wireless Laser Mouse 5000 ** Tags removed: needs-upstream-testing -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1260513 Title: 045e:00f9 [Gateway DX4860] Horizontal scrolling is broken with 9-button Microsoft Wireless Laser Mouse 5000 Status in “xserver-xorg-input-evdev” package in Ubuntu: Triaged Bug description: horizontal scrolling is broken with the 9-button Microsoft Wireless Laser Mouse 5000.
