There was an issue with one of the repositories that Bodhi uses this week. Even thought we are based around Ubuntu 10.04, some of the backporting the team does causes some core Ubuntu packages for 10.04 to no longer be compatible. Not a big deal, we roll our own for these few packages.
One thing we had not counted on was the few backports Ubuntu provides to it's LTS releases and this week one of these backports was the package xserver-xorg-video-geode. As you might have guessed this is one of those packages that is no longer backwards compatibly with Bodhi. In fact, if you went to upgrade this package via apt-get or one of it's GUI front end such as Synaptic you would be presented with a warning message telling you that installing this new package may break your system along with a list of conflicting packages that would be removed (nearly the entire system).
Thats a pretty good warning message, I wasn't terribly concerned about getting this one package corrected right away - I had other more pressing things to work on.
The moral of my little story here? Listen to your package manager! (that and I need to stay on top of the lucid backports a little bit better) Whenever you are doing anything on a GNU/Linux system that requires the root password you should be sure to understand everything that is going to be done to the system before agreeing to it. This can save you a lot of headaches and broken machines down the line!
