Public bug reported: I am running Xubuntu 15.10, with xscreensaver (I uninstalled light- locker since at least on my Thinkpad X200, I cannot reliably resume from suspend with it, possibly due to https://bugs.launchpad.net/ubuntu/+source/xubuntu-default- settings/+bug/1303736 ).
With 15.04, I didn't have problems with suspend, but lately it has this strange behaviour where it'll resume from suspend when I unplug the laptop from AC after closing the lid. I let acpi_listen run while first closing the lid, then counting to five, then unplugging AC, then counting to five, then plugging it back in, counting to five, then opening the lid, here's the log: $ acpi_listen|while read -r l;do echo "$(date) $l" ; done to. 05. nov. 18:25:52 +0100 2015 button/lid LID close to. 05. nov. 18:26:01 +0100 2015 battery PNP0C0A:00 00000080 00000001 to. 05. nov. 18:26:01 +0100 2015 battery PNP0C0A:00 00000080 00000001 to. 05. nov. 18:26:01 +0100 2015 processor LNXCPU:00 00000081 00000000 to. 05. nov. 18:26:01 +0100 2015 processor LNXCPU:01 00000081 00000000 to. 05. nov. 18:26:01 +0100 2015 ibm/hotkey IBM0068:00 00000080 00006030 to. 05. nov. 18:26:01 +0100 2015 thermal_zone LNXTHERM:00 00000081 00000000 to. 05. nov. 18:26:07 +0100 2015 ac_adapter ACPI0003:00 00000080 00000001 to. 05. nov. 18:26:07 +0100 2015 processor LNXCPU:01 00000080 00000002 to. 05. nov. 18:26:07 +0100 2015 processor LNXCPU:00 00000081 00000000 to. 05. nov. 18:26:07 +0100 2015 processor LNXCPU:01 00000081 00000000 to. 05. nov. 18:26:07 +0100 2015 ibm/hotkey IBM0068:00 00000080 00006030 to. 05. nov. 18:26:07 +0100 2015 thermal_zone LNXTHERM:00 00000081 00000000 to. 05. nov. 18:26:07 +0100 2015 battery PNP0C0A:00 00000080 00000001 to. 05. nov. 18:26:09 +0100 2015 battery PNP0C0A:00 00000080 00000001 to. 05. nov. 18:26:15 +0100 2015 button/lid LID open ^C So as the output shows, it was only suspended between lid close and battery unplugged. I'm running xfce4-power-manager 1.4.4-4ubuntu1 on 15.10. ** Affects: xfce4-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/1513564 Title: resumes from suspend if AC unplugged To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfce4-power-manager/+bug/1513564/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
