evolution itself was not installed (actually not upgraded from 11.04); I removed libgl1-mesa-glx I also removed evolution-common/plugins but kept getting errors about dependence on libevolution when I tried to install.
I then tried to clean up with apt-get autoremove (a suggestion given in the output of the earlier remove commands. Unfortunately the shutdown entry in the menu did not work and when I turned the computer off the Ubuntu graphical interface was not there. Worse yet, I am not sure I can get to the console. I tried to access the Setup after powering. My monitor does not show anything before GRUB - in particular no messages about booting alternatives, setup etc - so I have to hit keys in the dark to stop the default boot to Ubuntu. I do not know what I may have changed, but my monitor is now uniformly lit, that is, I get a blank screen, which I get rid of by turning off the computer. I do not know why some packages were not upgraded properly from 11.04. I'd appreciate any advice you may have, but I know it is no longer a support issue.
