I marked it as invalid as the bug you demonstrated was not in SNA, and the other logs did not show a normal boot procedure so I had no reference otherwise. As it stood the attached logs explained your observed behaviour and showed the bug elsewhere.

Restarting after that then gives the 'System is running in low graphics mode' message. I get this everytime now. Have re-installed with latest build and same issue. I can only boot in recovery mode UPDATE: In the ubuntu forums thread (http://ubuntuforums.org/showthread.php?t=2115355), jbicha, recommended the following which fixed (or worked around) the problem "Perhaps this is a problem with SNA which has been enabled by default for raring.
