Today I logged into my workstation and things looked different than before the weekend. Starting window manager settings from the XFCE4 settings manager didn't work either.
After some headscratching (and running xfwm4-settings from the command line to get it's messages) I found out that Ubuntu had decided to run metacity instead of xfwm as window manager - no idea why.
To get rid of it, the hard way:
aptitude purge metacity gnome-session
update-alternatives --set x-session-manager /usr/bin/xfce4-session
