Touchpad vertical scrolling doesn't work after upgrade to 2.6.32-19 (Sony VAIO EB1E1E, AlpsPS2/2 ALPS)

I am affected by this bug as well. I run a vanilla ubuntu lucid install on an hp pavilion dm3-1039wm (alps touchpad).

I have the same issue Sony VPCEB15FX E series.
Running Kubuntu 10.04 beta2

AlpsPS/2 ALPS GlidePoint touchpad.

I can get tap to click but no scrolling - either along the side or as a two finger gesture. The scroll along the side works in Win. It is registering the action in that the pointer moves down the screen but it doesn't recognize it as a scroll action. Turning on or off in the Kubuntu settings works for tap to click but does not work to
- disable touchpad
- enable any kind of touchpad scrolling.

Scrolling is also not working in VPCEB15EL in Lucid.

Hi Rocky,

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.

Thanks Jeremy,

Following the instructions at https://wiki.ubuntu.com/KernelTeam/MainlineBuilds?action=show&redirect=KernelMainlineBuilds and getting the kernels from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=A , I installed three kernels (Not including Kubuntu 10.04's default kernel); one was successful.

The kernel to solve this problem is:
v2.6.33 ~ http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33/

The three that proved unsuccessful were:
v2.6.32-21-generic ~ The default
v2.6.34-rc5-lucid ~ http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-rc5-lucid/
v2.6.34-999 (Daily 2010-04-29-lucid) ~ http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2010-04-29-lucid/

Rocky,
     Would you mind trying out the kernels mentioned by Josh above? This will help me and the team narrow the possible bits affecting whether this works or not.

Thanks!

Hi Jeremy,

I got the same results as Josh, but I don't think 2.6.33 solves the problem - it is just old (from 25-Feb-2010) and doesn't recognize the touchpad same as 2.6.32-18 and older 2.6.32 kernels.
My guess is that with these kernels the touchpad is not recognized and a generic driver is loaded with which the vertical scrolling is working. But because the settings are not editable other features such as disabling tapping while typing and scrolling using multitouch gestures can't be used.

Here is the outcome of my tries:

v2.6.33 - http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33/
Same as 2.6.32-18 - the vertical scrolling *is* working, the touchpad is not recognized and the settings are not editable (same as shown in touchpad_2.6.32-18.png)

v2.6.34-rc6-lucid - http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-rc6-lucid/
Same as 2.6.32-19 - the vertical scrolling *is not* working, the touchpad is recognized, the settings are editable, but don't take any effect (same as shown in touchpad_2.6.32-19.png)

v2.6.34-rc1 - http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-rc1/
Couldn't boot with this kernel.

Regards,
Rocky

I have exactly the same problem described by the OP on a VAIO VPCF111FB. Before kernel 2.6.32-19, the touchpad was detected as if it was a wheel mouse. Touchpad options in kcm-touchpad were grayed out (disabled), but it worked all right, including scrolling. Since 2.6.32-19, the touchpad is detected as an ALPS Touchpad and these settings are editable, but scrolling does not work anymore.
Running Kubuntu 10.04 64 bits fully updated (kernel 2.6.32-21-generic).

In response to bug #550625, Chase Douglas was able to get scrolling to more or less work in Lucid with the pre-release versions of the 2.6.32-22.33 kernels - see discussion thread here:
https://bugs.launchpad.net/ubuntu/+s...ux/+bug/550625
When I upgraded to the Lucid final release last night, I lost edge scrolling on my HP Mini 311 (ALPS GlidePoint trackpad) again. I downgraded linux-image-2.6.32.22-generic from the final release back to version 2.6.32-22.33~pre201004281000 (one of the versions with Chase's fix) and edge scrolling successfully returned to the ALPS GlidePoint trackpad. There is still no separate tab for the trackpad within Mouse Preferences, but at least all the basic functionality is there.

I'm having the same issue with touchpad scrolling being unrecognized. I'm using the official release of 10.04 32-bit. Kernel is 2.6.32-21. Laptop is an Acer Aspire 7736Z-4088 with ALPS touchpad.

I made the scrollarea work by adding the code from the thread below.
http://ubuntuforums.org/showthread.php?t=1467503

This works for my Acer Aspire 7738G

Works for me, too. Cool to have a workaround finally, thanks!

to have it permanent, add the following to /etc/modprobe.d/psmouse.conf:

options psmouse proto=imps

I run a Sony VPCF11S1E

Today I updated to linux-image-2.6.32-22-generic (version 2.6.32-22.33) from the official lucid repositories, but edge scrolling doesn't work when I remove the workaround from comment#15. As written in the bug description I'm using Sony VAIO EB1E1E.
It's good we have the above workaround in the mean time.

The workaround worked for me on my HP pavilion dm3.

Sony Vaio VPCEB1S1E is also affected but workaround fixed the problem.

Latitude E6410 with the same problem. I've tested "proto=imps" as arguments for psmouse with no luck :-(

Packard Bell Easynote TJ65 with the same Problem. "proto=imps" fixes scrolling.

The proto=imps DOES NOT solve my scrolling.

In fact, it makes the touchpad work ALWAYS but the vertical scrolling is gone forever. Synaptics is not to be loaded either:

(EE) Synaptics Touchpad Unable to query/initialize Synaptics hardware.
(EE) PreInit failed for input device "Synaptics Touchpad"

By the way I am checking now these solutions, in case somebody is interested to try them as well:

proto=imps doesn't help me either, but Synaptics seems to be loaded fine:

Confirmed that none of the solutions proposed here work:

I believe it is a problem on synaptics trying to find my touchpad. See my complete Xorg.0.log.

And my xorg.conf file

This bug was fixed in the package linux - 2.6.32-23.37

Is that package available via update-manager ?

I do not seem to find it

Rocky, if the bug is fixed, is there a way for the rest of us to apply the fix? (hoping it comes through Update Manager soon).

@oooh and thefluxster
The fix is in for linux-image-2.6.32-23-generic so if you have upgraded to this kernel already and you still have the issue you probably have a different touchpad.
I'm using the "Main server" (KpackageKit > Settings > Edit Software Sources > Download from) and linux-image-2.6.32-23-generic is available and I auto updated to it through the KpackageKit auto update.

from "uname -a" I get:
    2.6.32-24-generic #38-Ubuntu SMP Mon Jul 5 09:22:14 UTC 2010 i686 GNU/Linux
and the current behavior is that edge scrolling works by the trackpad being emulated as a PS/2 mouse and Synaptics is not being used. I have no trackpad tab or options in System--Preferences--Mouse. This was exactly the same as in 2.6.32-23.

This was with an ALPS Glidepoint trackpad on an HP Mini 311

Latitude E4310 with the same problem. I've tested "proto=imps" as arguments for psmouse without luck.
