touchpad movement drastically reduced and unconfigurable in latest xorg-x11-server update
Last modified: 2014-06-27 15:20:53 EDT
Description of problem:
Upon rebooting with xorg-x11-server-Xorg.x86_64 1.14.4-10.fc20 I found that my touchpad was extremely sluggish. I went into the Mouse and Touchpad settings in Xfce and attempted to adjust the Acceleration and Sensitivity but these had no effect. A full swipe across the touchpad might just move the cursor a couple inches across the screen. The same movement in xorg-x11-server-Xorg-1.14.4-5.fc20.x86_64 can get me 80% across the screen.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Use your touchpad in Fedora 20 with xorg-x11-server-Xorg-1.14.4-5.fc20.x86_64
2. Upgrade to xorg-x11-server-Xorg.x86_64 1.14.4-10.fc20
Notice a drastic decrease in motion and that it seems to be unconfigurable.
Mouse behaves the same as in previous releases.
Downgrading to xorg-x11-server-Xorg-1.14.4-5.fc20.x86_64 restores the old behavior.
The touchpad is listed as ETPS/2 Elantech Touchpad in Xfce Mouse and Touchpad
/proc/bus/input/devices has it as:
I: Bus=0011 Vendor=0002 Product=000e Version=0000
N: Name="ETPS/2 Elantech Touchpad"
H: Handlers=mouse0 event5
B: KEY=6420 30000 0 0 0 0
Bluetooth mouse seems unaffected by this problem:
I: Bus=0005 Vendor=19ff Product=0207 Version=0245
N: Name="Rocketfish Apple Bluetooth Mouse"
H: Handlers=mouse1 event14
B: KEY=1f0000 0 0 0 0
xorg-x11-server-Xorg-1.14.4-9 seems to work fine, so I guess it's just -10 that is affected thus far.
Can confirm this issue on two of my laptops, both using ALPS touchpads. They both also have trackpoints which are unaffected. USB mice I've tried have been unaffected.
This is /proc/bus/input/devices from the laptop I'm on now.
I: Bus=0011 Vendor=0002 Product=0008 Version=0300
N: Name="AlpsPS/2 ALPS DualPoint TouchPad"
H: Handlers=mouse1 event6
B: KEY=e420 70000 0 0 0 0
Downgrading to xorg-x11-server-Xorg-1.14.4-5.fc20.x86_64 which is what I had before -10 solved it for me on both laptops.
Fallout from 1104789, revert is underway though I'm not sure what the problem is yet.
