I'm having major problems with Ubuntu crashing every day so I'd like to try something different. I tried Googling for a list of packages in Oneiric Ubuntu Minimal but couldn't find anything.
I'd like to try a system that doesn't have Zeitgeist installed, but as it seems to be so tightly integrated into Ubuntu I wondered if it was still present in the Minimal version.
No. As far as I'm aware, Zeitgeist currently is only used in Gnome.
