Touchpad does not work properly in Ubuntu 11.04

Bug Description

After installing Ubuntu 11.04, my touchpad has no vertical scroll. I googled and found the defect can be solved by typing following commands:

$ echo "options psmouse proto=imps"|sudo tee -a /etc/modprobe.d/psmouse.conf
$ sudo modprobe -r psmouse; sudo modprobe psmouse

And as a result the touchpad scrolling is back. However, the "touchpad" tab in the "gnome-mouse-properties" is gone (see the attachment) , and I lost syndaemon support to avoid touchpad making trouble when typing.

To sum up, the touchpad is either treated as a touch device with no scrolling, or a 3d-psmouse with no touch device system support.

Below is the result of running tpconfig

Found Synaptics Touchpad.

Sorry I forgot to mention I am working on Ubuntu 11.04 of Simplified Chinese. The attachment may cause confuse. The point is there's no touchpad tab in the picture, or else there should be 3 tabs in the gnome-mouse-properties GUI.

Sounds like a kernel issue with your specific hardware. Can you run 'apport-collect 784965' in a terminal?

Me too. My touchpad works, but the scrolling no. The two finger scrolling too...

I have the same issue with my Acer 532h. I have had no luck with this touchpad and it is very frustrating. I was so happy to see that the touchpad tab in the mouse settings was back in this release, only to find I have no scrolling.

Same issue here on Dell Latitude E6320. Scrolling on the side works, but there is no way to access/change touchpad settings.

Same issue with Dell Latitude e6500: no vertical or horizontal scrolling, no touchpad tab in mouse setting.

Also, no touchpad in xinput or devices.

Dell E6520 has identical problems. No touchpad settings, right side scrolling does work.

I blogged out the full answer.

Brief summary. Install the "psmouse" patch following instructions you find here:

After that, 1) no more random cursor movements while typing 2) tap to click, right side scroll, and doubleclick to grab will work.

Dear Paul, are u sure it's a universal fix that works for all models, or just work for Dell laptops ? Since in the patch I see some keyword like Dell Latitude E5500.

P.S. , what model are u using ?

As far as I know, it is for all of those "mysterious" ALPS devices that are not recognized as touchpads. The patch is distributed from Dell, that's why it mentions their models. My laptop happens to be Precision M4600, if that helps.

One of the frustrating things about tracking this down is that Dell just calls the device "Dell MultiTouch", but MS Windows sees it as ALPS touchpad. But we don't know the ALPS model number, so far as I know. But Several folks in the other bug trackers seem to say the "patch" works on their different kinds of laptops.

Maybe this info will be useful for us...
This is the standard situation on my vaio sb:

$ xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Mouse id=12 [slave pointer (2)]
⎜ ↳ AlpsPS/2 ALPS GlidePoint id=13 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
    ↳ Video Bus id=6 [slave keyboard (3)]
    ↳ Sony Vaio Keys id=7 [slave keyboard (3)]
    ↳ Video Bus id=8 [slave keyboard (3)]
    ↳ Power Button id=9 [slave keyboard (3)]
    ↳ USB 2.0 Camera id=10 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]

I've attached the output of the commands "xinput list-props 12" and "xinput list-props 13"


$ xinput list-props 12
 Device Enabled (126): 1
$ xinput list-props 13
 Device Enabled (126): 1

Hope you will resolve this frustrating bug...
