Description Simon Kohlmeyer 2012-07-22 12:55:51 UTC
After upgrading x11-drivers/xf86-input-evdev to 2.7.0, emulateWheel stopped working in the vertical direction with a Kensington Expert Mouse (it's actually a trackball).
Horizontal scrolling still works, as does the actual mouse wheel on the device.
xev does not show any input at all when trying to scroll with the emulated wheel.

Installing 2.6.0 and restarting X fixes the problem. 

Reproducible: Always

Steps to Reproduce:
1. Upgrade to x11-drivers/xf86-input-evdev
2. Restart X or reboot
3. Try to scroll using the emulated mouse wheel.
Actual Results:  
No input events are sent to applications.

Expected Results:  
Scrolling works as usual.

Too long, will be attached.

Comment 4 Chí-Thanh Christopher Nguyễn gentoo-dev 2012-07-22 13:02:18 UTC
Can you check whether xf86-input-evdev-9999 from the x11 overlay is also affected, and if yes report this upstream at too?
Comment 5 Simon Kohlmeyer 2012-07-22 13:20:04 UTC
The error still occurs with xf86-input-evdev-9999, I'll report this upstream.
Comment 6 Ryan Pennucci 2012-07-25 22:27:57 UTC
I'm seeing the same thing.  Downgrading to xf86-input-evdev 2.6.0 or xorg-server 1.12.2 will eliminate the issue.

Submitted to upstream at
Comment 7 Matt Turner gentoo-dev 2017-01-26 06:09:54 UTC
This was fixed in xorg-server-1.13.0.
