Bug Description

Binary package hint: xserver-xorg-input-synaptics

Installed Ubuntu 10.04 LTS desktop on my new Sony Vio VPCF126FM and touchpad is not detected. This problem fist occurred during install. The touchpad has never worked, from booting from the live CD, installing Ubuntu, and then updating Ubuntu.

If I attempt to run System/Preferences/Touchpad the following error message results:

GSynaptics couldn't initialize.
You have to set 'SHMConfig' 'true' in xorg.conf or XF86Config to use GSynaptics

I can not find the xorg.conf or XF86Config files.

Sudo tpconfig results with the following message.

Found Synaptics Touchpad.
Firmware: 8.96 (multiple-byte mode).

If I plug in a USB mouse, the USB mouse works.

There is not response from touching the touchpad or touchpad buttons. The touchpad works under windows.

I have attached the dmesg file that the following web page instructed me to do:

Hi Wesley,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

I installed headers and kernel 2.6.36-999-generic. No change, touchpad is still not detected.

The following was installed.

linux-headers-2.6.36-999_2.6.36-999.201009211548_all.deb
linux-headers-2.6.36-999-generic_2.6.36-999.201009211548_i386.deb
linux-image-2.6.36-999-generic_2.6.36-999.201009211548_i386.deb

Then the computer was restarted. Touchpad still not detected.
"tpconfig" yielded output
"Could not open PS/2 Port [/dev/psaux]"

Clicking "System - > Preferences -> Touchpad"
yielded following output: "GSynaptics couldn't initialize.
You have to set 'SHMConfig' 'true' in xorg.conf or XF86Config to use GSynaptics""

Had the same problem on a Sony Vaio VPCF12C4E with 10.04, solved adding "i8042.reset i8042.noloop" kernel parameters.

After upgrading to 10.10 RC the problem persists and the above workaround no longer works.

Solved in Maverick adding i8042.nopnp kernel parameter.

I have a Sony Vaio fz-21m and with Lucid 10.04 the touch-pad was working well out of the box.
After upgrading to Maverick 10.10, I can only move the mouse arrow, but nothing happen if I tap or try to use the side scroll. If I want to click I can just use the buttons, I cannot tap on the touchpad

Adding i8042.nopnp doesn't solve the problem.

Any hints?

Okay.

I added the fix that was posted in bug 636842.

Now the touchpad works. The multi-touch features work. I can tap twice to left-click, and scroll on the right side of the touchpad.

The fix was posted here: http://davidsterry.com/blog/2010/09/ubuntu-10-04-32-bit-on-sony-vaio-vpcf121gx/

Except I used gedit to modify the file.

1. Run: sudo gedit /etc/default/grub
and modify it so the GRUB_CMDLINE_LINUX line looks like this: GRUB_CMDLINE_LINUX=”i8042.nopnp”
2. Run: sudo update-grub
3. Reboot.

Thanks to everyone that helped.

Wesley Epperly: Did multitouch work "just work" after adding the i8042.nopnp to grub or did you have to do something else?

Yes, that was the only change that I made to force the touchpad to work. Unless going to a different kernel and making that change made it work. Regardless, everything that I have done is posted in this bug.

Let me clarify. The touchpad works. Multi-touch features work. But the sensitivity of the touchpad seems to be much different then under windows. I sometimes have to press with a bit of pressure to make it work. So the sensitivity does not seem to be constant. But I'm not really sure about this. But it is quite usable.

Same problem on a VPCEA3CFX running 64-bit Maverick. @wepperly's solution on #10 worked as a charm. Thanks!

I had this same issue on a fresh install of 10.10 through Wubi on a Sony VAIO VPCEE3WFX. After installing all the updates the trackpad works, but the right-side scroller doesn't work, even after trying the above grub edit.
