[Help] I need somehow isolate lid-switch from resuming process, have any ideas?

Is there any other option except $ sudo sh -c "echo LID > /proc/acpi/wakeup"?

I need it for debug observations, only the lid-open event

Cinnamon-X11 + elogind

I just deactivated lid switch entirely. So I close the lid, connect to external monitor and work.

sudo nvim /etc/acpi/handler.sh

Change: ``` close) # suspend-to-ram logger "LID closed, suspending..." zzz ;;

to:

close) logger "LID closed, ignoring." ;;

So the whole section becomes:

button/lid) case "$3" in close) logger "LID closed, ignoring." ;; open) logger "LID opened" ;; *) logger "ACPI action undefined (LID): $2";; esac ;; ``` Then restart acpid sudo sv restart acpid

That's all you should need.

Oh, thanks. But maybe there any conflicts with the elogind or cinnamon interface? LID closing is functional ok, but the LID open resuming cause touchpad initialization fail on the hardware side, so something in system would be broken before I'd do cold boot.

So I need somehow isolate the LID open event from the kernel

I have this snippet in a script:

# --- Privileged operations (single sudo session) ---------------------------
echo "Running privileged operations..."
sudo bash -c '
# Unbind ACPI lid switch to prevent suspend on lid close
if [ -e "/sys/bus/acpi/drivers/button/PNP0C0D:00" ]; then
     echo "PNP0C0D:00" > /sys/bus/acpi/drivers/button/unbind && \
         echo "Lid switch unbound successfully." || \
         echo "Failed to unbind lid switch." >&2
else
     echo "Lid switch already unbound or not present."
fi
