Intermittent behaviour from touchpad

[Paul Sinnett]

There are a lot bugs in this section that I don't see but I think this is different from those described in other reports.

I am trying out Edgy Knot 2 on an Acer Aspire 1360. The touchpad continues to work correctly on Dapper with the exception of the scroll feature.

On Edgy the scroll function now works but normal pointer movement occasionally and temporarily stops for no apparent reason. There are no log messages when this happens or any spikes in any running processes. Also, I can still move the cursor around with a USB mouse during such a freeze.

Let me know if you want me to run any diagnostics.

Here's my xorg.conf

Oops. This time!

I've upgraded to Knot 3 and the cursor freeze still happens but the scroll feature has stopped working as well.

[Paul Sinnett (paul-sinnett)]

This appears to be fixed now. The cursor has yet to freeze on me. The scroll feature is also working again. I'm not sure which update fixed these issues.

[Paul Sinnett (paul-sinnett)]

Both problems are back with Edgy Knot-3 install.

Still have both scroll and freeze problems in Edgy release and Feisty Herd 1.

I now have some additional info on the freeze. When it happens, the following messages appear in kern.log:

this is still happening with the latest build (Feisty Beta)

It looks to be the same bug than this one : https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/109445

Seems to be fixed in Hardy Beta

Reporter says it's fixed in Hardy.
