Bug Description
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.
If I change "Turn off screen when inactive" to 1 minute, then the screen turns off after 1 minute as it should, but if I set it back to 1 hour then the screen goes back to blanking after 10 minutes, not turning off after 1 hour as it should. So it seems that there are two independent timers and the GUI has no effect on the 10 minute one.
Looking in xset, there is indeed a 10-minute screen blanking timeout.

Note that I am using a dual head configuration so I have an xorg0.conf and an xorg1.conf, but there is nothing in either related to screen blanking. Both heads experience the same problem. My other machine that I upgraded from 12.04 to 12.10 does not.
Running "xset s 0 0" avoids the problem.

Workaround: add this to xorg.conf (in my case, to both of them):
Section "ServerFlags"
Option "BlankTime" "0"
