I just upgraded an Ubuntu machine from Ubuntu Dapper to Gutsy. For starters, don't do this. The supported path is D -> E -> F -> G, but I'm hax0r, so I wanted to do it in one step. It's possible, but took a lot more effort than it was worth.
Gutsy has Compiz as default, but the upgrade left me with no window decoration (borders, title bar, etc). I did what I thought was deleting my entire GNOME prefs/gconf tree, but still didn't get a fix. I did find the answer eventually: re-enable the decorator plugin.
You can do this, and enable a good bunch more also, like so:
gconftool --set /apps/compiz/general/allscreens/options/active_plugins \ --type list --list-type string \ '[gconf,png,svg,decoration,wobbly,fade,minimize,cube,rotate,zoom,scale,move,place,switcher,screenshot,resize]'
This hard to find answer was bought to you by Brice Goglin's blog.

worked for me
You can do the same installing the "compizconfig-settings-manager" - started via "ccsm" on the commandline - or in the settings menu via "Advanced Desktop Effect Settings".
Choose "Decoration" in category "Effects".
Thanks for the tip, hard to find answer indeed
Compiz always left me with no window decorations (Debian Lenny here). I seem to only have the core compiz components, no GUI whatsoever. I didn't track this to a lack of default gconf options. Now it's working as it should. I might as well try installing some sort of GUI configurator, because fiddling with gconftool is not really my type of fun.
