Public bug reported: Assume that "Suspend when inactive for" values in "System Settings / Power" are set to "5 minutes" and "Don't suspend" for columns "On battery power" and "When plugged in".
Now assume that the system has been plugged in and inactive for 6 minutes. Finally, assume that the system becomes unplugged. In Ubuntu 14.04, the system does not suspend. The 5 minute countdown to automatic suspend begins when the unplug event occurs, such that the timeout event occurs 5 minutes later. This behavior is correct. In Ubuntu 14.10, the system automatically suspends immediately after the unplug event occurs. This behavior is incorrect. Or minimally, this behavior is undesired in the normal case. The 5 minute timeout was intended to protect against battery energy being drained during a continued period of the system being inactive AND unplugged. In this case, in contrast, the period of the system being unplugged just began. There has been no continued period of the system being inactive AND unplugged. This difference represents a regression in functionality for the 14.04 to 14.10 upgrade. ** Affects: 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/1415653 Title: 14.10 incorrect suspend when inactive logic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1415653/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
