Can you test the latest mainline kernel[0] to see if commit c0394506e69b37c47d391c2a7bbea3ea236d8ec8 fixes this bug?

Kernel 3.6-rc4 have the same behavior.

------------------

From: Seth Forshee <email address hidden>

commit c0394506e69b37c47d391c2a7bbea3ea236d8ec8 upstream.

The touchpad on the Acer Aspire One D250 will report out of range values
in the extreme lower portion of the touchpad. These appear as abrupt
changes in the values reported by the hardware from very low values to
very high values, which can cause unexpected vertical jumps in the
position of the mouse pointer.

What seems to be happening is that the value is wrapping to a two's
compliment negative value of higher resolution than the 13-bit value
reported by the hardware, with the high-order bits being truncated. This
patch adds handling for these values by converting them to the
appropriate negative values.

The only tricky part about this is deciding when to treat a number as
negative. It stands to reason that if out of range values can be
reported on the low end then it could also happen on the high end, so
not all out of range values should be treated as negative. The approach
taken here is to split the difference between the maximum legitimate
value for the axis and the maximum possible value that the hardware can
report, treating values greater than this number as negative and all
other values as positive. This can be tweaked later if hardware is found
that operates outside of these parameters.

Anca: I'm unclear as to the precise nature of your problem. Is the touchpad completely broken, or is it just vertical scrolling that's broken?

In either case it appears that your touchpad is behaving outside of the specification for Synaptics touchpads, as the patch shouldn't have any impact on devices behaving within the specification. Once you've clarified exactly how your touchpad is malfunctioning I'll add some debug code to the driver to help us diagnose what's going wrong.

Hi Seth, only the vertical scroll is not working as before. I need to insist scrolling, try again, work, not work, try again... etc.

Seth,

I can confirm the same observation here. After building my own kernel (and reverting your patch) as Anca describes in comment #4 and booting it, vertical scrolling works again as it should.

Thus, I suppose my own bug report (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1046504) is a duplicate.

Best,
Jonas

Thanks. I've put the test build at the link below. Please install, then install the input-utils package and reboot into the debug kernel.

After rebooting, try to avoid touching the touchpad. Use Ctrl-Alt-F1 to switch to a virtual console and log in. Run 'sudo lsinput' and identify the touchpad device in the ouput, making note of the number of the associated input device (e.g. if the device is /dev/input/event0 then the device number is 0). Then run 'sudo input-events devnr > input-events-lr.txt', where devnr is the device number from lsinput. Drag your finger slowly across the touchpad from the extreme left to the extreme right, keeping the virtical position of your finger roughly near the center of the touchpad, then press Ctrl-C. Next run 'sudo input-events devnr > input-events-tb.txt' and drag your finger from the extreme top to the extreme bottom with the horizontal position roughly in the center, then press Ctrl-C. Then run 'dmesg > dmesg.txt'.

After that you can switch back to the desktop by pressing Ctrl-Alt-F7. Please attach intput-events-lr.txt, input-events-tb.txt and dmesg.txt to this bug. Thanks!

Thanks to both of you. I understand what the problem is now, but the behavior I'm seeing could be interpreted differently depending on the touchpad so I'm a bit unsure how to handle it at this point. I'm working on it though, and I'll try to have something to test in the next couple of days.

alright. Let us know if you need anything else. Knowing these kind of hw-problems, I'll be happy to help!

Btw, I don't know if that is of any help: The behavior you describe in the original patch that we reverted (jumping cursor) was/is present here.

Seth,
works almost for me. :) That is, the vertical scroll area is almost in the correct place. It's much better than without your latest patch, but the scroll area is still shifted a little bit to the left. Scrolling on the far right edge of the touchpad sometimes works, sometimes not.

Jonas

Let me correct my previous comment #18: Previous versions of the linux kernel (e.g., 3.2.0-27-generic) exhibit exactly the same vertical scroll behavior as your latest patched version. So I can second Anca: "Works for me". :)

Jonas

This bug is awaiting verification that the kernel for Precise in -proposed solves the problem (3.2.0-32.51). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-precise' to 'verification-done-precise'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
