Title:
Touchpad scrolling and tapping stops working after a while
Status in “xserver-xorg-input-synaptics” package in Ubuntu:
Confirmed
Bug description:
When I boot into my system, an ASUS Zenbook UX31, the elantech
touchpad works fine. I have a small script to configure it which is
run when my session starts, and those parameters are applied fine
without problem.
Here is the script, in case something in there might be relevant :
#!/bin/sh
synclient FingerLow=9 FingerHigh=12
synclient MinSpeed=2.0 MaxSpeed=4.0 AccelFactor=0.1
synclient VertTwoFingerScroll=1 HorizTwoFingerScroll=0
synclient CoastingSpeed=10 CoastingFriction=25
synclient TapButton1=1 TapButton2=3 TapButton3=2
synclient EdgeMotionMinZ=30 EdgeMotionMaxZ=40 EdgeMotionMinSpeed=100
EdgeMotionMaxSpeed=400
synclient PalmDetect=1 PalmMinWidth=5 PalmMinZ=1
#must restart syndaemon to set those params.
killall syndaemon
syndaemon -i 1 -t -K -d
The issue is that after a while, some features of the touchpad stop
working. They include tapping (one-two-three fingers) and two-finger
scrolling. The clickpad functions are still working. I haven't been
able to pinpoint the exact issue yet.
I have encountered this issue with many kernels, including 3.4.0-rc6
kernel and the one in this report.
