Bug Description
About once a day at random times my dual screen multimonitor setup suddenly goes black and then reverts back to mirror setup. Mostly it occurs while watching flash videos in my browser but yesterday it happened while no videos were playing and I just tried to click on the messaging menu indicator applet.
This happens on Unity 3d and 2d
Using the nouveau driver, have not tried the prop nvidia drivers. Don't really want to as I do not want to use nvidia's buggy multimonitor setup tool. I would like to get the built in Ubuntu display manager working right. Especially since new work is being done to make it work really well in many different test cases
Thanks

Additional issues have arisen since the latest update and while in unity 3d. Before the update when I had to fix the screen, after it randomly switched back to mirror, the launcher was always draw about 2/3 of the screen. Likeit was stuck at a lower res. Now that issue no longer occurs BUT now the indicator applets are not functioning properly. When I click messaging the MEmenu comes up, in fact the Me menu comes up when you click on almost any indicators, only sometime does the correct indicator menu open. Very annoying to have to log out and in again all day long when this screen does this
