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
oracpid
, 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

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?
Kernel version: 3.6.2-1-ARCH
Answer
Edit /etc/systemd/logind.conf
and make sure you have
HandleLidSwitch=ignore
which will make it ignore the lid being closed. (You may need to also undo the other changes you’ve made.)
Then, you’ll want to reload logind.conf
to make your changes go into effect (thanks to Ehtesh Choudhury for pointing this out in the comments):
systemctl restart systemd-logind
Full details over at the archlinux Wiki.
The man page for logind.conf also has the relevant information,
HandlePowerKey=
,HandleSuspendKey=
,HandleHibernateKey=
,
HandleLidSwitch=
Controls whether logind shall handle the system power and sleep
keys and the lid switch to trigger actions such as system power-off
or suspend. Can be one of “ignore”, “poweroff”, “reboot”, “halt”, “kexec”,
“suspend”, “hibernate”, “hybrid-sleep” and “lock”. If “ignore”, logind will
never handle these keys. If “lock”, all running sessions will be
screen-locked; otherwise, the specified action will be taken in the
respective event. Only input devices with the “power-switch” udev tag
will be watched for key/lid switch events.HandlePowerKey=
defaults to “poweroff”.HandleSuspendKey=
andHandleLidSwitch=
default to “suspend”.HandleHibernateKey=
defaults to “hibernate”.
