[JMC] Yes, these are exactly the packages that upgraded at the time of the
issue.  Nothing else.  Definitively not unity or compiz packages.  I held off
taking those updates.

[JMC]  Possibly, but, I've seen other posts online where an issue with the
driver causes the blank screen and mouse pointer.  I'm thinking it might be a
delay or race condition with Upstart or LightDM waiting on Xorg to start, but,
root cause stems from radeon (ie. the warning messages.)  Also, Xorg.0.log
shouldn't fill up with 30MB of warning messages in 8 hours...

[JMC] I have not tried this.  Will try it and report back.

[JMC]  Agree.  I believe it was just coincident that radeon and Mesa updated at
the same time.

[JMC] Thanks for taking the time to look at this Michael.  Pls let me know if
there is anything you would like to see form the system.
