Description: Ubuntu Raring Ringtail (development branch)
Release: 13.04
This may or may not be relevant... Upgrade from Precise Pangolin has
not been easy. The screen when logging in using a Unity window
manager is devoid of contents: no dash and no lens. The unity plugin
in the dash was not enabled, so I used ccsm to enable that. I used a
gnome session to create a brand new user account. This new user
account is able to login using Unity.
Crashes are not connected with any particular application startup.
