I've set up dual monitor display in Fedora 15/Gnome 3.

However, the windows failed to display on my secondary monitor.(mouse can drag these missing windows on secondary monitor, I just cannot "see" them) How to solve this problem?

This question came from our site for professional and enthusiast programmers.

How do you have this second monitor configured? can you by chance post a screenshot of your display settings? – MaQleod Sep 8 '11 at 20:58

I found something similar here. The following is a quote from the site that could be helpful.

1) install gconf-editor ( yum install gconf-editor ).

2) run gconf-editor either via a terminal or else from Applications -> System Tools -> Configuration Editor

3) navigate to apps --> compiz --> general --> allscreens --> options and edit the active_plugins node on the right

4) put "place" in the series right after "resize" (with commas and such to keep them seperate)

5) disable & re-enable desktop effects.
