Sorry about that. That was a typo. I meant to say: quantal 1:1.0.2-0ubuntu3 precise 1:0.0.16+git20111201+b5534a1-1build2 > > 0.0.16 is known to behave like that - you need to upgrade to >= 1.0. In other words, I have >= 1.0. But you suggest that it shouldn't happen with >= 1.0 Should I report it on the nouveau list at freedesktop.org ? -- Kees
