ALPS Touchpad on Dell E6510 not recognized as touchpad

[_the_mars_]

The touchpad is recognized as PS2 mouse. It is working, but the special features (e.g. disable touchpad while typing) cannot be enabled, because it is not detected as a touchpad.
Running Linux l00771 2.6.38-8-generic #41-Ubuntu SMP Tue Apr 5 19:30:49 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux.

Patching psmouse.ko as below solves the problem (found on https://confluence.nau.edu/confluence/display/~<email address hidden>/Recognize+ALPS+Touchpad+on+Dell+E6510+in+Ubuntu):

 static const struct alps_model_info alps_model_data[] = {

I now have the module psmouse.ko installed and running and I have the trackpoint (stick) and trackpad identified:

Latitude-E6510 share # xinput -list

⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]

However I do not have scroll functionality, nor does gpointing-devices have any control over disabling the trackpad, adding scroll, etc.

Did you get those functions to work?

As a workaround, I have the middle button for the trackpad working to assist with vert/horiz scroll when pressed. Works on Dualpiont Stick and trackpad when held.

I just posted a pointer to an upstream bug in comment #14 to bug 749508 - you might pick up some information from there.

Lets look at this as a configuration problem. I mean, after applying the psmouse patch, and the system sees the device, how can we control it?

I've got a new Dell Precision M4600 and it has the ALPS touchpad that other people are struggling with. I've found many bug reports on it on all of the Linux sites.

I applied the patch, as you described, and after that the touchpad seems to be recognized as a touchpad. Commands like "synclient -l" do recognize the device and print out settings. However, changing the parameters with synclient has no discernible effect, and I'm uncertain whether this means

 the synclient commands are having no effect, or

 the gnome operating system is fighting with me for control of the touchpad.

Or, possibly,

 even though the system seems to see it has a touchpad, this particular touchpad is still controlled as a mouse. Watch what happens if you go into the mouse controller in gnome, and in the "newly revealed" touchpad control area, you turn off the options like "click to tap". Even after that, the click to tap still works.

$ xinput -list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ DualPoint Stick id=12 [slave pointer (2)]
⎜ ↳ AlpsPS/2 ALPS DualPoint TouchPad id=15 [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)]
    ↳ Laptop_Integrated_Webcam_FHD id=10 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]
    ↳ ACPI Virtual Keyboard Device id=13 [slave keyboard (3)]
    ↳ Dell WMI hotkeys id=14 [slave keyboard (3)]

And more good news:
I know for sure the patch makes a difference, since this output is definitely different and encouraging

$ cat /proc/bus/input/devices

I: Bus=0011 Vendor=0002 Product=0008 Version=7326

B: PROP=0
B: EV=b

Before the patch, I was getting the "no device or driver" error from synclient, now I get this, however, changing the settings has no effect on behavior of the touchpad.

$ synclient -l

    LeftEdge = 153
    RightEdge = 870

Same problem with Sony VAIO E-series.
