Comment 81 for bug 419328

Still crashing for me on a Lenovo T60 with the symptoms described in the original bug report.
I used the updates in proposed. If you want to test them, but don't want to install all updates in proposed, do the following:

In a terminal, run:
gksudo gedit /etc/apt/preferences

Copy this into the editor window and save:
Package: *
Pin: release a=karmic-proposed
Pin-Priority: 400

In a terminal, run:
sudo aptitude install -t karmic-proposed compiz compiz-core compiz-gnome compiz-plugins compiz-wrapper libdecoration

Reboot, attach monitor, and be happy. Or not, like me.
