Laptop does not stay suspended

no dock, not charging. suspend → suspends itself for a bit, then immediately wakes up.

I managed to fix it yesterday by turning off LID as a suspend mechanism

trying:

$ sudo -i
# echo LID > /proc/acpi/wakeup

wasn't enouhg

# echo XHC > /proc/acpi/wakeup

and yeah looks like XHC was the one.

and yep, it's XHC

it does work when I disable wakeups via the XHC, but it means I can't wake up the laptop when it's docked now

laptop is currently not staying suspended when on battery, and out of dock.

$ cat /proc/acpi/wakeup | grep enabled
PEG0	  S4	*enabled   pci:0000:00:01.0
XHC	  S3	*enabled   pci:0000:00:14.0
RP01	  S4	*enabled   pci:0000:00:1c.0
RP08	  S4	*enabled   pci:0000:00:1c.7
RP09	  S4	*enabled   pci:0000:00:1d.0
AWAC	  S4	*enabled   platform:ACPI000E:00
SLPB	  S3	*enabled   platform:PNP0C0E:00
LID	  S4	*enabled   platform:PNP0C0D:00

why was the tmpfiles.d thing not taking effect?

because i didn't in fact add it?! duh. let's just get XHC in there.

I guess I could disable USB devices one by one and see which one is doing that?

adding to /etc/tmpfiles.d/suspend-fix-xhc.conf:

# see https://trilium.agentydragon.com/share/laptop-does-not-stay-suspended
w /proc/acpi/wakeup - - - - XHC

and looks like that worked. I guess it's OK that it doesn't wake up from dock now.
