I have been experimenting with my effects in Compiz (on Ubuntu 9.04).
I clicked the blur effect, everything that can move has turned black, therefore whenever I log on everything turns black.
I have managed to open a guest session blindly. But i wouldn't be able to do the same disabling it.
Is there a way to disable the blur effect I have set?
So far I have only found post link text and nothing listed there seemed to work, perhaps the last comment might work, but I don't understand how to do that.
