Public bug reported: When i configure my system too "when on battery suspend when inactive for 30 minutes" then when on AC power when screen blank the back light is not turned on when activate keys or mouse pad. The system is not dead if I close the lid to make it suspend then i immediately can wake system and screen back light turn on correct. If I change the setting too "Don't suspend" problem does not occur. Despite the setting is for battery powered and problem happens when AC plugged in.
Bad setting: on battery: Suspend after 30min, when lid is closed suspend, when power critical low hibernate. When plugged: Don't suspend, when lid is closed suspend. Good setting: on battery: Don't suspend, when lid is closed suspend, when power critical low hibernate. When plugged: Don't suspend, when lid is closed suspend. ** Affects: gnome-power-manager (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/870873 Title: screen does not turn on backlight with specific power setting in controlcenter To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/870873/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
