I've found that I can make the system stable with the following settings: System Settings: Privacy>Screen Lock: On Power>Dim screen when inactive: Off Power>Blank screen: 10m Power>Automatic suspend: On Battery Power: On Delay: 20m Plugged In: On Delay: 1h Power>When the Power Button is pressed: Suspend Devices>Displays>Night Light Off Gnome Tweaks (installed): Power>Suspend when laptop lid is closed: On
Upgraded BIOS. Graphics are: IntelĀ® Sandybridge Mobile NVidia Optimus It seems to hang with "Night Light" and "Dim screen when inactive" enabled. So, I have those off. I originally had "Night Light" enabled with sunrise and sunset. That caused my system to try to hang around sunrise and sunset. And it generally would hang when unsuspending after one of those options activated. Anyhow, I will be trying this out sometime soon to prevent that sort of trouble: http://www.akitaonrails.com/2017/03/14/enabling-optimus-nvidia-gpu-on- the-dell-xps-15-with-linux-even-on-battery I expect that will allow me to use the "Night Light" and "Dim screen when inactive" options. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1757445 Title: Suspend does not always resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1757445/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
