Synaptics / ALPS Touchpad not Working in OpenSuSE 11.3 KDE

[kizbot777]

It is my understanding that using OpenSuSE 11.3, there is no xorg.conf file. My /etc/X11/ directory does not have an xorg.conf file. It is also my understanding that the later distros instead use /etc/X11/xorg.conf.d/ directory which contains several setup files for devices. In the /etc/X11/xorg.conf.d directory there is a file named 20-synaptics.conf. Unfortunately, this file does not ever seem to load properly since my device is listed as "ImPS/2 Generic Wheel Mouse" under xinput list command. My /etc/X11/xorg.conf.d/20-synaptics.conf reads as follows:

Section "InputClass"
       Identifier "touchpad catchall"
       Driver  "synaptics"
       MatchIsTouchpad "on"
       MatchDevicePath "/dev/input/event*"
       Option  "HorizScrollDelta"      "99"         # enable horizontal scrolling
       Option  "VertTwoFingerScroll"   "True"       # enable vertical two-finger scrolling
       Option  "VertScrollDelta"       "99"
       Option  "TapButton1"            "1"          # 1-finger tap = left mouse click
       Option  "TapButton2"            "3"          # 2-finger tap = right mouse click
EndSection

My /var/log/Xorg.0.log reads as follows from my most recent bootup:

Can someone please help me figure out how to get this working. It is so frustrating that it is about to send me back to Windows, which trust me, I don't want to do. I am using an Acer Aspire 5740-6491 which uses an ALPS touchpad. My understanding is that the synaptics driver should work just fine with an ALPS touchpad. Also, I cannot use gsynaptics as I get an error reading:
"GSynaptics couldn't initialize.
You have to set 'SHMConfig' 'true' in xorg.conf or XF86Config to use GSynaptics". Again, this distro does not use xorg.conf file. Additionally, I cannot use the "Configure Desktop" "TouchPad" in KDE which I believe uses ksynaptics because I get an error reading "Warning: Touchpad configuration is not supported on this system. The synaptics driver is either not loaded or too old. Refer to the documentation for information about the required driver version."

I have also tried adding the grub boot option "i8042 nopnp=1" as some forums said to try but this did not help either. Please help if you have any ideas. Thank you.

Can you post the output of

cat /proc/bus/input/devices

Gsynaptics is deprecated. Try GpointingDeviceSettings.

Try adding to /etc/X11/xorg.conf.d/20-synaptics.conf

Section "InputDevice"
  Driver      "synaptics"
  Identifier "TouchPad"
  Option      "SendCoreEvents"
  Option      "Protocol" "auto-dev"
  Option      "SHMConfig" "on"
EndSection

If that fails change the Protocol from "auto-dev" to "alps" and see if that helps.

Thanks for the ideas reed9. I did not get any different results by changing the 20-synaptics.conf to the settings you recommended. Here is the output of "xinput list"

:~> xinput list

I also thought this might be useful. It is an ls of /dev/input/by-path that shows some mouse listings

platform-i8042-serio-1-event-mouse

Any other ideas? Thanks again for the input.

From what I can find, it looks like a known bug. Most the references I've found are for Ubuntu, but since it seems to be a kernel issue it should, it's probably distro agnostic.

Best I can recommend is to try a newer kernel out and see if it resolves the issue.
