I'm not talking about a large scale swap. I mean exchanging a few
machines that have chronic jumpyness. So that the developers have
machines that they can test on. Yes its a known bug... but whats not
know is the exact cause or how to fix it.
Touchpad problems are listed in many deployments. Our biggest hurdle to
fixing it having reliable way to duplicate the problem. It seems to
happen lots out in the wild its very hard to reproduce on demand and its
pretty rare here at 1cc.
The 8.2 kernel has a bunch of stuff to try to help but without solid
test cases its a bit of guess work to see what difference the new
We have a new touchpad that queued up for production. That will hit
sometime next year when the current supply is out. Initial reports are
that its much better than the current model. However see my next, post.
That may not solve it 100%
I still want to fix the issues with the current pad but I'll need
If you can help here's what I need:
1) Serial number ranges for laptops that have have jumpy problems.
2) Laptops that are unlocked and people willing to run kernels with
driver changes in areas where the problem is common.
3) As much data as possible on the conditions surrounding the laptop
when the jumpyness happens.
