Gutsy with Compiz enabled and Separate X displays

Hi,
Thank you all for the great job that you are doing with Ubuntu.

I've a problem with a separate X displays configuration in Gutsy. I've installed Gutsy rc on a desktop (dual core, nvidia 6600gt, 1gb ram) and configured separate X displays to be able to attach my plasma tv (a Panasonic) over Component. I've compiz enabled with custom settings. I can see the image perfectly on my tv, but if I let compiz running on both screens, on the primary (LCD) some things run very slow (like after minimizing a window, it takes like 3 seconds or more to unminimize). I've changed /usr/bin/compiz to include --only-current-screen in the default options and now everything works smooth on primary screen, but on the second there are no window borders (there weren't any also when compiz was enabled for both screens). Also, I cannot use the keyboard on the second screen (I can open a movie with the movie player and I can make it full screen on the second screen only by using the mouse).

Do you have any sugestions?

Regards,
Marriouss
