dmesg output

Description of problem:
My hp Pavilion dv6 synaptics touchpad is being detected as a pointer by X server.

I have tried to comment out evdev touchpad catchall portion in /usr/share/X11/xorg.conf.d/10-evdev.conf AND enabling a synaptics InputClass in another file /usr/share/X11/xorg.conf.d/10-synaptics.conf, but no luck.

My problem is that I cannot disable touchpad with evdev. With synaptics driver, I could disable tap when required. Simple tasks like typing becomes very frustrating with the touchpad  getting accidental taps.

Version-Release number of selected component (if applicable):

X.Org X Server 1.12.0
Release Date: 2012-03-04

How reproducible:
Random (Some times the synaptics driver loads fine (automatically) and I get output for synclient -l. But other times, I get 

   Couldn't find synaptics properties. No synaptics driver loaded?

This is true whether or not I attach the external Logitech Optical USB mouse at boot time.

Steps to Reproduce:
1. Boot laptop
2. Check with synclient -l if synaptics driver got loaded.
Actual results:
Random experiences with synaptics or evdev driver loaded after loading X server

Expected results:
Synaptics driver loaded every time.

Device is recognised as PS/2 generic mouse only which is a sign that the kernel does not yet switch this device into touchpad mode. Reassigning.
Comment 7 Josh Boyer 2013-03-14 14:30:30 EDT
Is this still happening with 3.8.2 in updates-testing?
