Greetings All

Today I allowed the automatic update on Ubuntu 12.04 64bit to run, this has now resulted in my machine only booting in low graphics mode and I cannot resurrect Unity. I have tried a number of methods but these have not helped at all. (e.g. sudo... update, upgrade; ctrl+alt+F7, etc).

There is some output data I have, which can be found at:

Any help to recover the system will be appreciated as (always) I have some important work in Blender, Salome and others that I have been bashing my head against a brick wall for a couple of months and need to continue working with for Uni .
