Confirmed on 12.10 Quantal Quetzal. This exact problem began happening to me after an upgrade from 12.04 to 12.10.
This seems to be a bug with the upgrade process screwing up power management settings. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-power-manager in Ubuntu. https://bugs.launchpad.net/bugs/899955 Title: On login ignores setting, turns off screen after idle timeout Status in “gnome-power-manager” package in Ubuntu: Confirmed Bug description: Steps to reproduce: 1. Disable power saving 2. (Re-)boot (logoff may suffice, though I've not tested this) 3. Login and don't touch mouse or keyboard after that 4. Wait What happens: Within half an hour (on my system at least) the display signal is turned off (monitor reports "No signal"). What you expect to happen: The screen to stay on as indicated by power saving settings. Additional info: 1. Any keyboard or mouse activity seems to make it obey the setting: after that the screen won't go blank on its own (irregardless of whether or not the bug has manifested itself during the session). 2. I've disabled screensaver as well, though that probably doesn't concern this bug. 3. From bug #854624's comments I picked up this settings listing command, in case it helps: jani@saegusa:~$ for c in `dconf list /org/gnome/settings-daemon/plugins/power/`; do echo -n "/org/gnome/settings-daemon/plugins/power/${c}="; dconf read /org/gnome/settings-daemon/plugins/power/${c}; done /org/gnome/settings-daemon/plugins/power/sleep-display-ac=0 /org/gnome/settings-daemon/plugins/power/sleep-display-battery=0 ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: gnome-power-manager 3.2.1-1 ProcVersionSignature: Ubuntu 3.2.0-2.6-generic 3.2.0-rc3 Uname: Linux 3.2.0-2-generic x86_64 ApportVersion: 1.90-0ubuntu1 Architecture: amd64 CheckboxSubmission: 09ae689090491ca53449589269e4bfd8 CheckboxSystem: edda5d4f616ca792bf437989cb597002 Date: Sun Dec 4 17:46:51 2011 EcryptfsInUse: Yes InstallationMedia: Ubuntu 9.10 "Karmic Koala" - Release amd64 (20091027) SourcePackage: gnome-power-manager UpgradeStatus: Upgraded to precise on 2011-12-01 (2 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/899955/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
