[Dell Inspiron 5547/5447] Unable to scroll with the clickpad

[Po-Hsu Lin]

CID: 201401-14530 Dell Inspiron 5547

The Clickpad on this system was detected as a SynPS/2 Synaptics TouchPad, I'm not sure if this is expected, but the scrolling feature is not working on 14.04 + update(both two fingers scrolling and one finger edge scrolling).
Also, the "disable while typing", three and four fingers tapping are not working as well.

Steps:
1. Install 14.04 + update (3.13.0-29), boot to desktop
2. Test the touchpad

Expected result:
* At least edge scrolling should work

Actual result:
* Only left / right click, one-finger single / double tapping works.

One finger edge scrolling, two finger scrolling, three / four finger tap work with the daily-live mainline kernel.
(except the "disable while typing" feature)

Also note that the SynPS/2 Synaptics TouchPad won't appear on the first boot (after installation), it will shows up after you reboot the system.

After installing the latest mainline kernel on 201401-14530, these two pointing devices still exist like before

It works with the latest mainline kernel as well (3.16.0-rc4)

Status changed to 'Confirmed' because the bug affects multiple users.

[Gaurav Juvekar (gauravjuvekar)]

I would like to add that DLL063E:00 06CB:2934 is the actual device which recognizes touch events for some reason.
Doing

xinput --test "DLL063E:00 06CB:2934"

and moving the pointer with the touchpad shows the motion events but there is not output for

xinput --test "SynPS/2 Synaptics TouchPad"

[Phil (pme991)]

I am experiencing this issue along with other issues (freezing, cursor jumping to trash, selecting text automatically) on new Dell Inspiron 5547 dual booting with Win 8.1 and Ubuntu LTS 14.04.1.

Let me know if other information is required or if I can test a fix. This bug is very frustrating.

[Brian (b6ian)]

I have exactly the same issue on Ubuntu 12.04 LTS. My right click also does not work unless I click with 2 fingers.

The kernel is 3.13.0-43-generic and 64-bit. I have a Dell Inspiron 5547 as well. I'd upgrade to a newer Ubuntu release, but I have a requirement to keep this version. Is there a supported way I can upgrade the kernel to 3.16? I saw someone else mentioned that kernel fixed their touchpad issues. Thanks.

[Po-Hsu Lin (cypressyew)]

@Brian,
You could install 3.16 kernel with "sudo apt-get install linux-generic-lts-utopic" command, but I think it's fixed in 3.13 kernel.

After re-tested with newer kernels, I noticed that with the 14.04 stock kernel (3.13.0-24), there is no "Synaptics Touchpad" in xinput output:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ DLL063E:00 06CB:2934 id=11 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
    ↳ Power Button id=6 [slave keyboard (3)]
    ↳ Video Bus id=7 [slave keyboard (3)]
    ↳ Power Button id=8 [slave keyboard (3)]
    ↳ Sleep Button id=9 [slave keyboard (3)]
    ↳ Integrated_Webcam_HD id=10 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)]
    ↳ Dell WMI hotkeys id=13 [slave keyboard (3)]

"Synaptics Touchpad" will appear with 3.13.0-29, scrolling does not work too.

However, after upgrade to 3.13.0-32 (or use 14.04.1 stock image), scrolling works as expected.
This also applies to the latest update (3.13.0-46 kernel).

Therefore I will close this bug with fix-released.
For those who still affected, please try to run "sudo apt-get dist-upgrade" to upgrade your kernel. Or give 14.04.1 / 14.04.2 a try.
If it's still not working, please feel free to open a new bug with "ubuntu-bug linux" for it.
Thanks!
