Bug Description

In 11.10, the Sentelic FingerSensingPad is treated as a mouse device but not a touchpad, so vertical scrolling is not supported.
Fn+F9 is supposed for locking/unlocking the touchpad but that doesn't work.

The driver to support this device has just been merged by Linus for 3.4-rc0, we should backport it for 12.04.

The touchpad device is:
I: Bus=0011 Vendor=0002 Product=000f Version=0000
N: Name="FSPPS/2 Sentelic FingerSensingPad"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input11
U: Uniq=
H: Handlers=mouse0 event11
B: PROP=0
B: EV=7
B: KEY=670000 0 0 0 0
B: REL=143

ubuntu@ubuntu-K53U:/dev/input$ sudo evtest ./event10
Input driver version is 1.0.1
Input device ID: bus 0x11 vendor 0x2 product 0xf version 0x0

Do you happen to know if this patch will be submitted to linux-stable?

People affected by this bug are probably wondering why the kernel team doesn't just apply the patch and fix it. The reason is that the kernel team is reluctant (not opposed) to apply any patch to a stable kernel that is not from upstream. Applying patches that don't come from upstream add greatly to the support of the kernel as other upstream patches may touch the same area as the non-upstream patch and may prevent them from applying cleanly.

Please do anything you can to get this in an LTS! It makes it very difficult to use my laptop and most modern laptops being released. Thanks!

@Jim, I've uploaded a testing kernel at http://people.canonical.com/~ycmiao/lp969334/, please help give it a try and see if that works for you. This is really late in the cycle and we cannot guarantee that the feature will be merged, but a verification of whether the patchset is OK will really be appreciated. Thanks.

@Eric: That kernel did the trick!!! The trackpad now recognizes as an actual trackpad in the settings and 2-finger scrolling works like a charm. Thanks! (Asus ROG G74SX Laptop)

Ike Panhc (ikepanhc) wrote :

With precise stock kernel (-22.35), OSD shows touchpad off on Fn+F9 event and touchpad is still functional.

With kernel in #4, Fn+F9 trigger touchpad on and off and OSD gives me the correct information.

The hardware is Asus K53U

Jim Raredon (decoy-umd) wrote :

I concur with the ASUS G74SX that the touchpad on/off hotkey on FN-F9 works now as well.

Many thanks to everyone; this response was impressive!!!! :)

It does not work with X54C-BBK7. Also, wireless does not work either with this kernel. The wireless card is detected and it recognizes the wireless networks but will not connect or even ask for security.

The kernel also does not work on Asus K53E-BBR15 with the same wireless issue.

wireless for the X54C-BBK7:
 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

wireless for K53E-BBR15
 Network controller: Atheros Communications Inc. AR9485 Wireless Network Adapter (PCI-Express) (rev 01)

Both use the ETPS/2 Elantech Touchpad, so this may not be relevant.....

Hello Anthony, or anyone else affected,

Accepted linux into precise-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

With precise-23.36 kernel, this issue is still around. After upgrade kernel to 3.2.0-24.37, Fn+F9 can toggle touchpad correctly.

I will say the varification is done.

With this new kernel installed from the repositories, now the trackpad doesn't work at all. :(

Jim Raredon (decoy-umd) wrote :

Ignore my last comment, it works fine now! (For some odd reason, two reboots instead of the typical one seemed to be the trick)

Hi,
My MIS-X370 has a sentelic touchpad, is running 12.04 with 3.2.0-24.39, so the touchpad should work, but side scrolling is not working. Side scrolling does work a little: when moving my finger, both the cursor move and the screen is scrolling, but both very jerky.
When switching on the touchpad, the kernel logs read: psmouse serio1: sentelic: Finger Sensing Pad, hw: 13.2.1, sw: 1.0.0-K
Is this a slightly different version? How can I get it working (and maybe help improving the driver) ?
