In some instances, bluetooth devices can prevent the device from going to sleep or cause spurious wake-ups. Add a note to the sleep script on how bluetooth can be turned off completely during suspend.

# Notes:
|
|
# - For IPTS, see
|
|
# > https://github.com/jakeday/linux-surface/issues/544#issuecomment-519126757
|
|
# for an explanation/discussion. We do not unload/reload modules for now as
|
|
# the IPTS drivers should be able to resume/suspend without this. If you
|
|
# experience any issues on suspend/resume, please file an appropriate issue or
|
|
# join the discussion linked above so that we can fix it. As a temporary
|
|
# workaround, you may want to uncomment the IPTS-related lines above.
|
|
# - For bluetooth: If you have spontaneous wakeups, you may want to disable
|
|
# bluetooth completely, regardless if any devices are connected or not, by
|
|
# removing the `! bluetoothctl info;` part as indicated in the comment (e.g.
|
|
# comment-out the original check and comment-in the one below). Note that you
|
|
# may be required to re-connect your devices after resume if you choose this
|
|
# change.
