Comment 7 for bug 987304

Daniel,

I tried 1, but that had no effect: the paues remain.

I also added GLXVBlank on to my Device section (since there is no xorg.conf needed when using nouveau, I simply created a file containing the text you provided, and according to /var/log/Xorg.0.log, it had an effect), but that did not make a difference. The "lack of smoothness" that I experience is more like dropping frames because there is not time to render them.

If I disable the unity plugin when using nouveau, everything immediately becomes smooth again, so I definitely think that the plugin is doing something funny.

Is there anything else I can do to help locating the cause of the issue?
