After I type in my username and password, all I get is the background color (light-orange by default) and a white box in the upper-left corner of the screen. This is the second time this week that this has happened. It always happens after using the update manager to "update" my computer. I got as far as having my GTK, emerald, and compiz the way I like it, and then this happens (twice now).

I am new to linux, and am wondering if maybe I should just wait for intrepid because I am having zero luck with hardy..
