This bug has starting affecting one of my production servers. I would
classify it as "critical". I turned off and uninstalled the screensaver
on this computer, but apparently that is not enough to prevent Ubuntu
from going to sleep.  It will go to sleep by itself even if there is NO
SCREENSAVER application installed on the operating system! That is a
CRITICAL BUG!!!

So, in an effert to stop the computer from going to sleep, I installed
XScreenSaver, and turned it to "never go to sleep, ever" settings. Now I
have to start XScreenSaver at startup, to try to PREVENT this machine
from going to sleep. But it doesn't work.

Every few days, I'll wake up and be logged out of the machine, server is
down, not live to the world. Downtime caused by this bug. If I then try
to log back in, it IMMEDIATELY logs me back out! I have to cold restart
the whole machine to get back in.

This bug is so critical that I may have to migrate away from Ubuntu if
there is no forthcoming solution.

Bug description:
  I get logged off from Ubuntu sometimes. There is no error message or
  any indication that it is going to log off. The screen goes black, and
  after 2-4 seconds, i get presented with the Ubuntu Log On Screen.

  There is no clear pattern (or at least if have not noticed any). One
  time i am working with Netbeans, another time i am using firefox. This
  also means that at present i can not clearly say what package might be
  causing this behaviour.

  I am fairly sure the problem lies in 12.04 (or more precise - the
  combination of 12.04 and the hardware i am using). I do not have the
  same problem running 11.04 or 11.10.
