Comment 17 for bug 245383

I can confirm this happens on -nv with two monitors attached (but not set up for dual-head).
I've also seen flickering on -intel on a laptop, although it's character differs from the -nv flickering I'm seeing, so not sure it's exactly the same problem. Possibly...

I'm closing out the xserver-xorg-video-nv task since we don't need it against both. I'll also move the xorg bug to the server since it's probably a server issue.

For people seeing flickering on hardy, you're almost certainly seeing something unrelated, since we use different versions of xserver and the drivers there.
