I forgot to mention that before demonstrating that "Night Light" and "Dim screen when inactive", I upgraded to the latest BIOS from Lenovo on 20 March (a day prior to posting #16 and before turning off the dimming features). It is the Lenovo 85UJ25US (1.46) BIOS, which is an upgrade from 8BET55WW (1.35). It was upgraded in hopes that it would resolve the problem.
Right after the upgrade (and before turning off the dimming features), I also turned off Security->Virtualization and Security->VT-d. I don't have a need for virtualization, and it was mentioned in posts elsewhere that it may contribute to the hang on suspend issue. -- 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
