since i switched to systemd I get a very strange bug when i open the lid after suspending to ram. Before the update the laptop just resumed, but now it resumes for roughly a second and then goes back to sleep right away. I have to wake it up by keypress after that.
I have tested it with Thinkpad X61, X121e and X230. The bug occours on all devices.
I had this very same problem when i did the switch. The thing was that there where two tools providing this functionality. The gnome power tool thing and some acpi feature started with systemd.
Try disabling one of them.
Which systemd feature is it? I cant find the right one.
Specifically HandlePowerKey=, HandleSuspendKey=, HandleHibernateKey=, HandleLidSwitch=
