Oneiric has been pretty stable for me for the last couple of weeks, but the latest updates (as of today, July 11) have led to trouble for me. I've observed this on 2 different machines: 1. On the login screen, the mouse is frozen. I have to remove and reinsert the mouse's USB connector before the mouse will move. 2. After I log in, I find myself in Unity 2D. I see no way to get back to the regular Unity 3D. Both these machines have Intel graphics cards; not sure if that matters. Have other people seen this? Is any workaround known? Thanks - adam
