Comment 6 for bug 61746

I have some new things to say about the problem :
(1) I'm using the radeon driver, not fglrx ;
(2) the problem occurs with 2.6.17-10.28 and 2.6.17-10.29
(3) but not with my trusty 2.6.15-27.48 (I upgraded from dapper recently)

What information could I provide to help with finding a solution?
