xorg.conf - synaptics touchpad misdetected?

[brian russell]

In breezy, a clean install correctly detected synaptics touchpads as such and worked out of the box, scrollpad and all. Now, in dapper 6.06 flight 7 clean install, instead of the xorg.conf lines:

Section "InputDevice"
        Identifier "Synaptics Touchpad"
        Driver "synaptics"
        Option "SendCoreEvents" "true"
        Option "Device" "/dev/psaux"
        Option "Protocol" "auto-dev"
        Option "HorizScrollDelta" "0"
        Option "SHMConfig" "on"
EndSection

*****************and*************

Section "ServerLayout"
 Identifier "Default Layout"
 Screen "Default Screen"
 InputDevice "Generic Keyboard"
 InputDevice "Configured Mouse"
        InputDevice "Synaptics Touchpad"
EndSection

in an xorg.conf file, theres the following stuff about a wacom tablet:

Section "InputDevice"
  Driver "wacom"
  Identifier "stylus"
  Option "Device" "/dev/wacom" # Change to
                                                      # /dev/input/event
                                                      # for USB
  Option "Type" "stylus"
  Option "ForceDevice" "ISDV4" # Tablet PC ONLY
EndSection

Section "InputDevice"
  Driver "wacom"
  Identifier "eraser"
  Option "Device" "/dev/wacom" # Change to
                                                      # /dev/input/event
                                                      # for USB
  Option "Type" "eraser"
  Option "ForceDevice" "ISDV4" # Tablet PC ONLY
EndSection

Section "InputDevice"
  Driver "wacom"
  Identifier "cursor"
  Option "Device" "/dev/wacom" # Change to
                                                      # /dev/input/event
                                                      # for USB
  Option "Type" "cursor"
  Option "ForceDevice" "ISDV4" # Tablet PC ONLY
EndSection

************ and ***************

Section "ServerLayout"
 Identifier "Default Layout"
 Screen "Default Screen"
 InputDevice "Generic Keyboard"
 InputDevice "Configured Mouse"
 InputDevice "stylus" "SendCoreEvents"
 InputDevice "cursor" "SendCoreEvents"
 InputDevice "eraser" "SendCoreEvents"
EndSection

I am not sure i understand the problem. Matthew?

[brian russell (vagemulo)]

i'm not too sure, what's going on here, but the thing is, in breezy
install the synaptics touchpad worked OK with no tweaking necessary, it
created an xorg.conf which mentioned synaptics, but then with each version
of dapper i've tried flight 5, 6, 7 there has been no support for the
synaptics touchpad. Here are the relevant threads:

http://ubuntuforums.org/showthread.php?t=164423

I've updated the wiki to accomodate for this problem:
https://wiki.ubuntu.com/SynapticsTouchpadHowTo

I'd love it if somebody could help out on this one, it's possible that the
wacom auto-detect is conflicting with the existing (in breezy) synaptics
stuff.

My laptop has the same problem. Pointing, clicking, right-clicking, and tap-to-click worked fine. The side-scroll and middle button did not.

I performed a "sudo dpkg-reconfigure -phigh xserver-xorg" and it corrected the problem, along with another xserver problem I had.

See https://wiki.ubuntu.com/LaptopTestingTeam/AcerAspire3003WLMi for more details.

I can confirm that this is also an issue in edgy. I had to comment out a lot of wacom stuff from xorg.conf.
The synaptics touchpad was set to /dev/psaux which caused, according to Xorg.0.log, the synaptics driver to be unloaded, although I could use it. However, by changing that to /dev/input/mice, everything works fine, with no synaptic errors or warnings in Xorg.0.log.
I haven't tried to run sudo dpkg-reconfigure with the -phigh flag set though. But shouldn't a standard reconfigure be able to create the right xorg.conf?

My laptop is a Fujitsu Siemens m1437g.

I've got a similar issue with Edgy on a Lenovo 3000 C100.

On a fresh installation of edgy, the touchpad was misconfigured. In fact there was only a mouse input section:
Section "InputDevice"
        Identifier "Configured Mouse"
        Driver "mouse"
        Option "CorePointer"
        Option "Device" "/dev/input/mice"
        Option "Protocol" "ExplorerPS/2"
        Option "ZAxisMapping" "4 5"
        Option "Emulate3Buttons" "true"
EndSection

and some wacom devices which I don't have.

I had to manually add a synaptics section (generated by dpkg-reconfigure)
Section "InputDevice"
        Identifier "Synaptics Touchpad"
        Driver "synaptics"
        Option "SendCoreEvents" "true"
        Option "Device" "/dev/psaux"
        Option "Protocol" "auto-dev"
        Option "HorizScrollDelta" "0"
EndSection

and modify the ServerLayout accordingly.
Now touchpad scrolling works.

Maybe this is due to the fact that a USB mouse was plugged in during the installation? Anyway the installer completely missed the touchpad.

On latest feisty (64 bit), the auto-configured xorg.conf does NOT include a synaptics record on two laptops I own. The standard mouse driver also works with the touchpad, except for the scrolling using the rightmost part of the touchpad.
On one of the laptops, there are two special buttons to scroll pages, and they also only work with the synaptics driver.

Why is the touchpad not autoconfigured?

Mathijs: see bug #89113

[Rohan Dhruva (rohandhruva)]

Same problem on feisty kubuntu/ubuntu release cd. It is misdetected as "wacom" rather than using synaptics. The laptop is Acer TravelMate 3260.

[Stephen Crosby (stevecrozz)]

Same problem here on my Asus A8n laptop. No scrolling, xorg.conf claims I have a wacom tablet. This is confirmed in Gutsy as of today's updates.
