Where do I look to change the calendar preference in Gnome Shell from Evolution to Osmo? I have uninstalled Evolution and installed Osmo. I have looked in all of the settings available in System Settings, Tweak Advanced Settings, Alacarte, and Configuration Editor (gconf-editor), but I am obviously overlooking something.
Is it safe to delete all references to evolution when I find them in gconf-editor? I assume I would have to do that as root since it does not seem like trying to do so as a regular user works.
What I want to do is when I click on the date/time on the top bar and select "Open Calendar", Osmo will open. Right now I just get a message: "Execution of 'evolution' failed: command not found." Of course it would fail since I removed evolution. However, I can't seem to find out where to change it to look for Osmo instead.
