On May 15 I upgraded gnome-shell and dependent modules. That corresponds to when gnome-shell started freezing. gnome-shell was freezing several times a day on my laptop. It has been a day and a half since downgrading and I have not had any freezes so far.
Here is what I had to do to downgrade after adding the snapshot repository: apt-get install gnome-shell=3.2.2.1-2 gnome-shell-common=3.2.2.1-2 libcogl5 libclutter-1.0-0=1.8.4-1 libcogl-pango0=1.8.2-1 gir1.2-clutter-1.0=1.8.4-1 gir1.2-mutter-3.0=3.2.2-1 libmutter0=3.2.2-1 Unfortunately, the downgrade removed evolution before I realized it. Eventually, I got time to figure out what needed to be downgraded to get evolution back. Here is what I had to do to downgrade evolution: apt-get install evolution=3.2.2-1 evolution-data-server=3.2.2-1 evolution-plugins=3.2.2-1 libclutter-gtk-1.0-0=1.0.4-1 libevolution=3.2.2-1 libmx-1.0-2=1.4.5-1 libcamel-1.2-29=3.2.2-1 evolution-data-server-common=3.2.2-1 libclutter-imcontext-0.1-0=0.1.4-2 libcluttergesture-0.0.2-0=0.0.2.1-6 -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
