Public bug reported:
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
