Hi Colton, thanks for testing it! It looks like the kernel correctly receives and delivers the ACPI events, but then it fails to perform the actual suspend to mem.
Can you try one more test? echo 1 > /sys/power/pm_debug_messages echo 0 > /sys/power/pm_async echo mem > /sys/power/state The first setting simply increases the PM debugging level (...and hopefully we can get more info from dmesg -w). The second one disables the asynchronous execution of the PM suspend and resume callbacks. If the problem is a race condition in some of those callbacks, this should prevent the race. Thanks. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/1865170 Title: lid close simply turns off laptop screen Status in gnome-session package in Ubuntu: New Status in linux package in Ubuntu: Confirmed Bug description: OS: Ubuntu 18.04 LTS (beaver-three-eyed-raven X92.1) ubuntu-session version: 3.28.1-0ubuntu3 Expected behavior: On laptop screen close, system should suspend Actual behavior: On laptop screen close, laptop screen disabled Previously, I triggered 'suspend when laptop lid is closed' in gnome- tweaks. This worked fine until about 2-3 days ago, when I came back to work with a dead laptop (I don't charge overnight, usually, but I do use a dock at work). Now, whenever I close my laptop screen, it doesn't trigger sleep - instead, it simply disables the laptop screen, resulting in my external monitor being used as the only output screen. Once I re-open my laptop, the laptop screen is re-enabled as the primary monitor. This happens regardless of connection to my dock. I tested this by unplugging my laptop, closing it, letting it sit for 3 minutes, then re-opening it. While the laptop was closed, fans still ran. When I re- opened my laptop, the lock screen didn't appear.
