Comment 0 for bug 1865170

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.

Results of attempted fixes:
- `mem_sleep`: no behavior change (files correctly modified)
- `pm-hibernate`: first run, hangs until I kill the process. future runs result in exit code 1.
- update bios: already on latest bios
- `logind.conf`: no behavior change
- gnome tweaks: no behavior change
