You have been subscribed to a public bug: I have a new install of 15.04. I am using lightdm with a unity desktop (default). I have two users on my system. Often when I log in or switch user unity or lightdm (I don't know enough to understand which one) will freeze on a corrupted display. The launcher icons and the launcher will be overwritten with some pseudo-random pattern. the bar across the top of the display will also be corrupted. Sometimes the display has both my desktop and the unity-login greeter mixed. I usually can't type or do alt-f2 for several seconds. At some point (usually several seconds later) the display will appear to "reset," sometimes once, sometimes several times and eventually will settle on an uncorrupted, usable screen. If I switch user 10 times this will happen on 8 of them.
