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" setting truly turns off the display and the display reports no signal. But possibly the reporter of bug 1046118 used the term "power down" loosely.

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. $ xset q Keyboard Control: auto repeat: on key click percent: 0 LED mask: 00002000 XKB indicators: 00: Caps Lock: off 01: Num Lock: off 02: Scroll Lock: off 03: Compose: off 04: Kana: off 05: Sleep: off 06: Suspend: off 07: Mute: off 08: Misc: off 09: Mail: off 10: Charging: off 11: Shift Lock: off 12: Group 2: off 13: Mouse Keys: on auto repeat delay: 500 repeat rate: 33 auto repeating keys: 00ffffffdffffbbf fadfffefffedffff 9fffffffffffffff fff7ffffffffffff bell percent: 50 bell pitch: 400 bell duration: 100 Pointer Control: acceleration: 2/1 threshold: 4 Screen Saver: prefer blanking: yes allow exposures: yes timeout: 600 cycle: 600 Colors: default colormap: 0x20 BlackPixel: 0x0 WhitePixel: 0xffffff Font Path: /usr/share/fonts/X11/misc,/usr/share/fonts/X11/100dpi/:unscaled,/usr/share/fonts/X11/75dpi/:unscaled,/usr/share/fonts/X11/Type1,/usr/share/fonts/X11/100dpi,/usr/share/fonts/X11/75dpi,/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType,built-ins DPMS (Energy Star): Standby: 0 Suspend: 0 Off: 0 DPMS is Enabled Monitor is On $ 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.
