Package: gnome-shell Followup-For: Bug #648854 One other thing that may, or may not be relevant. The "Graphics" section of the "Details" part of the System Settings shows that I'm using the "Fallback" experience with an "Unknown" driver. I believe that previously I was *not* using the fallback mode (and I didn't select it this time around). lsmod shows the "radeon" module loaded.
I've attached a screenshot of the Settings page, and also the output of lsmod & lspci, in case they are relevant to anything else.
