I'm using archlinux. It never auto-suspend before a recent system upgrade(maybe I updated the kernel?).
I think it is related to laptop-mode or acpid, so I stop them:
/etc/rc.d/laptop-mode stop
/etc/rc.d/acpid stop
I also edit /etc/laptop-mode/laptop-mode.conf:
ENABLE_LAPTOP_MODE_TOOLS=0
Then I edit /etc/acpi/actions/lm_lid.sh, commented out the last line:
# /usr/sbin/laptop_mode auto
But all of above don't work. Following lines were found in /var/log/kernel.log(unrelated lines omitted):

I think this is not caused by pm-susend, because /var/log/pm-suspend.log don't log anything.
I don't want my laptop go to sleep when I close the lid. How to do it?
