trackpad jumps all over,randomly clicks

[mwa]

HP mini 311: upgraded to linux-image-2.6.38-10-generic and trackpad was totally unusable. Cursor jumps off in random directions, clicking whatever it hits, resizing windows, clicking links... Total demonic possesion.

trackpad is still mis-identified as per https://bugs.launchpad.net/ubuntu/+source/linux/+bug/527890. Note message #75 indicates patches for similar Dell products affected scrolling. I suspect similar patches made things worse

Crap. Note that apport ran on linux-image-2.6.38-8-generic since I couldn't use it on -10-

I can run anything command line only on -10- and attach more information is needed.

mwa, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. As well, please comment on which kernel version specifically you tested.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream', and comment as to why specifically you were unable to test it.

Please let us know your results. Thanks in advance.
