how can I remove Evolution and all related packages? I feel like I don't need them.
I tried twice to remove Evolution following the advise above. The result was that the panels disappeared. The system was Ubuntu 11.04.
The only way I have found so far is to run
sudo apt-get install unity-2d. This returns the panels and the functionality of Ubuntu. And yes, Evolution has disappeared. Unity-2d returns the icons, I have just managed to get rid of the indicator. It seems that the panels are connected to Evolution somehow.
I'm running gnome-classic on 12.10. When I uninstalled evolution it also uninstalled
gnome - this last made me nervous but in fact things work fine after - and after login the desktop is ready in a fraction of the time it used to be. (oh and I suggest removing zeitgeist also if you don't use the desktop search features - this also slows things down at login).
