Hi Jeremy.

Thanks for your email.

I definitely intend to test this with new versions of Ubuntu, and I would
love to assist you guys to solve this issue. I was waiting for the first
official release of Lucid that's supposed to come out tomorrow (the 29th). I
am now using the nv alternative video driver, and I'm pretty sure once I
switch back to NVidia the bug will come back.

Before upgrading to Lucid, would it be helpful it I run 'apport-collect -p
linux 527149' with my current version of Karmic and post the results?

Also, about upstream testing - should I do it before or after having
upgraded to Lucid? And once I upgrade to Lucid, won't I already have the
latest kernel version? If not - then what's the right order to do things?

Thanks again, Tal
