I have an HP x2 Detachable Notebook (model 10-p018wm) on which I've installed Fedora 29. Pretty much everything about the notebook works: the touchscreen is recognized, the WiFi works, and the media keys work. However, I can't get it to properly suspend to RAM. I have configured in KDE to have it suspend when the power button is pushed, and when the lid is closed. Yet after about a minute, the screen lights up, and it awakens. I have tried changing the configurations in
/etc/systemd/logind.conf to handle the lid (i.e. setting
HandleLidSwitchDocked=suspend), but that doesn't work.
Interestingly, when I boot up the notebook, log in to KDE, and press the power button, it seems to suspend for a while. Yet when I try closing the lid, it will wake up after about a minute.
I had thought that it was due to the WiFi spontaneously turning on and off. But after disabling the kernel modules (
iwlwifi) that doesn't seem to be the case. I also tried disabling bluetooth (both the kernel modules and the systemd service), but that didn't work, either.
Here are some of the facts. The notebook is UEFI-based, running kernel 5.0.8-200.fc29. The contents of my
/etc/default/grub file are as follows:
GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="rhgb quiet initcall_debug no_console_suspend" GRUB_DISABLE_RECOVERY="true"
I put in the "initcall_debug" and "no_console_suspend" parts so that I could see what exactly is going on during pre-suspension and post-suspension. Here's a journal log of when I pressed the power button, a log of when I closed the lid, and a log for when I tried pushing the power button after closing and then opening the lid.
Edit #1: I guess I should mention that the contents of
/proc/acpi/wakeup is empty; when I use the
cat /proc/acpi/wakeup command, I only get the line
Device S-state Status Sysfs node.
Edit #2: Here's the output from using
echo 1 | sudo tee /sys/power/pm_debug_messages in suspending:
