        <pre>The xorg log that you attached seems fine. That was produced after the hang? If
so, it must be the compositor hanging. Try disabling the compositor.

As for your gnome-related question, I don't know -- I stay away from
gnome-shell & co; however it's very unlikely that it'd be possible to restore a
session after X exits, due to the way that the X protocol works. However if X
stays alive, no reason (in theory) that you can't restart your WM. (In fact,
most WMs support this explicitly.)</pre>
