After updating from Ubuntu 12.04 Precise to Ubuntu 12.10 Quantal, X11
has started automatically blanking the screen after 10 minutes of
inactivity even though I have set "Turn off screen when inactive" in
"Brightness and Lock" to 1 hour.

This is a real usability issue. I have a Mac Pro running two Ubuntu VMs
and I never want them to activate screensavers/sleep mode/locked screen
--the Mac Pro has its own power-saving features. The 12.04 VM works
correctly, but the 12.10 has no easy option to stop the screen from
turning black.

Clean install will not change anything, because I installed ubuntu 12.10
(not upgraded), and still have this bug.
Seems to be a bug in Ubuntu (config).
To permanently correct this, add this line at the top of
/home/YOU/.profile :
xset s 0 0
The file should look just like this :
# ~/.profile:
I have this problem, have never heard of multi-head/multi-seat but the
problem arose a while after upgrading to 12.10. Most of this discussion
is way over my head, but I would very much like to resolve this issue
without having to clean-install again. Can somebody please publish step-

I am using only lightdm and Unity. My lightdm.conf is attached above.
Also, in my case the screen does _not_ power down after 10 minutes, it
just displays black. i.e., the HDMI display connected to it shows that
it is still receiving a signal. By comparison, the "Turn off screen when
inactive" set
I believe this is actually a duplicate of bug 1046118 but I thought that
required at least gdm to be running. Do you know for sure whether you
are using gdm or lightdm for your logon screen?

Thanks Alan. To my knowledge, Ubuntu actually has _never_ had a UI to
control this--screen blanking has always been disabled before. The UI
only allows the user to configure the time period for powering off the
display. Now it seems that screen blanking is mysteriously enabled on
some machines in 1

Yes, I have the same problem after upgrading, I'm running dual monitors
from a Acer TravelMate 5530, one on the HDMI port and one on the VGA
port. I've tried both answers on http://askubuntu.com/questions/207131

I have now upgraded two other computers to 12.10 and neither of them
experience this issue ...
To the other people experiencing this bug: are you also using multi-head
/multi-seat? (If you've never heard those terms before, the answer is
probably no.)

I think the default value of 10 minutes is coming from
