I am having the same problem in Ubuntu 12.10 using unity. Just thought I would mention this as most people here seem to be using gnome. It's driving the crayz. I've dug through so many settings and tried a few command line work arounds suggested on other forumns, but every 10 minutes on the dot the machine suspends (assuming I am inactive, watching a video). I've turned off lock. I've set "Turn screen off when inactive for:" to never. I've set "Suspend when inactive for" to "Don't Suspend" both when plugged in and when on battery. No luck.

Status in GNOME Shell: Fix Released Status in “gnome-settings-daemon” package in Ubuntu: Fix Released Status in “gnome-shell” package in Ubuntu: Fix Released Status in “gnome-settings-daemon” source package in Quantal: Triaged Status in “gnome-shell” source package in Quantal: Triaged Bug description: [IMPACT] * Regardless of settings in the "Brightness and Lock" Panel, screen will power off after 10mins. As part of the new lock-screen in gnome-shell 3.6 (when running on gdm), a watchdog timer, that disables the builtin X screensaver was moved into gnome-settings-daemon 3.6. Previously this was in gnome- screensaver however that is no longer used with gnome-shell/gdm combination. Since Quantal is still using gnome-settings-daemon 3.4, currently we are missing the watchdog timer for gnome-shell session on gdm. This is an upstream git patch take from gnome-settings-daemon 3.6. [Test case] 1. Run gnome-shell from gdm. 2. Set "Turn screen Off" in Brightness/lock panel to Never 3. Wait 10mins and the screen will turn off. [Workaround] Install gnome-settings-daemon 3.6 from gnome3-team ppa. [Regression Potential] The code in this patch was copied from gnome-screensaver into gnome-settings-daemon, so should not cause any problems. However when running a session that uses gnome-screensaver (Unity, gnome-shell on Lightdm), this watchdog timer will be duplicated. This is probably harmless but it might be best to patch it out gnome-screensaver. === Original Bug report === Just updated to the latest quantal today and then tried to watch a movie in Totem. Screen powered off every 10 minutes, reliably. Tried setting the power save to 'never', or to '1 hour', tried it with auto screen lock on or off, screen always powers off after 10 minutes exactly. $ lsb_release -rd Description: Ubuntu quantal (development branch) Release: 12.10 $ apt-cache policy gnome-control-center gnome-control-center: Installed: 1:3.4.2-0ubuntu13 Candidate: 1:3.4.2-0ubuntu13 Version table: *** 1:3.4.2-0ubuntu13 0 500 http://ca.archive.ubuntu.com/ubuntu/ quantal/main amd64 Packages 100 /var/lib/dpkg/status $ apt-cache policy totem totem: Installed: 3.4.3-0ubuntu2 Candidate: 3.4.3-0ubuntu2 Version table: *** 3.4.3-0ubuntu2 0 500 http://ca.archive.ubuntu.com/ubuntu/ quantal/main amd64 Packages 100 /var/lib/dpkg/status $ apt-cache policy gnome-screensaver gnome-screensaver: Installed: 3.5.5-0ubuntu1 Candidate: 3.5.5-0ubuntu1 Version table: *** 3.5.5-0ubuntu1 0 500 http://ca.archive.ubuntu.com/ubuntu/ quantal/main amd64 Packages 100 /var/lib/dpkg/status Let me know what other information is needed to troubleshoot this and I'll gladly help, thanks.
