 Posted: Wed May 13, 2020 2:30 pm Post subject: [SOLVED] Stop elogind suspending upon closing laptop lid |
 |
|
Hello, something that's been bugging me ever since switching from consolekit to elogind, is that elogind has configured it so that when I shut my laptop's lid, the system suspends.
I wouldn't mind this, but since it fails to resume property (I get a black screen upon resuming), it means if I accidentally shut down my lid, I then have to do a hard reset. I have no idea why elogind's suspend doesn't resume property, since both and | Code: | | echo mem > /sys/power/state |
resume just fine. I can confirm that it's elogind cuasing this, because if I run it similarly fails to resume from suspend.
I have tried adding /etc/systemd/logind.conf with "HandleLidSwitch=ignore", but this failed to fix the problem, the system still goes to suspend mode when I close the laptop lid. Any ideas?
EDIT: Just fixed it. Instead of creating /etc/systemd/logind.conf, the correct file is /etc/elogind/logind.conf. Just put | Code: | | HandleLidSwitch=ignore |
there instead.

If you use elogind correct place for add it is /etc/elogind/logind.conf or is a typo?

Yup, you're right. Putting it in /etc/elogind/logind.conf fixed it. I just assumed was in systemd without checking first, so that's my bad. |

gddman,
Does your laptop have an NVIDIA GPU, by any chance? I had the same problem as you did and, as I don't mind the laptop suspending when I close the lid, I resolved the problem with a script 04-nvidia-drivers in the directory /lib64/elogind/system-sleep/ as listed below.
| Code: | #!/bin/sh
#
# Unload nvidia modules on hibernate or suspend
# Load nvidia modules on thaw or resume
function unload_if_loaded() {
MODULE=$1
if lsmod | grep "$MODULE" &>/dev/null; then
rmmod $MODULE
fi
}
case $1/$2 in
pre/*)
unload_if_loaded nvidia_drm
unload_if_loaded nvidia_modeset
unload_if_loaded nvidia
# echo "Suspending/Hibernating" >> /dev/null
;;
post/*)
modprobe nvidia_drm
# echo "Resuming/Thawing" >> /dev/null
;;
*)
exit $NA
;;
esac |
If you use KDE and also have trouble with screen corruption upon resuming this way, I had success by creating a script 02-toggle-compositing in the same directory:
| Code: | #!/bin/sh
#
# Turn off compositing on hibernate or suspend
# Turn on compositing on thaw or resume
username=fitzcarraldo
userhome=/home/$username
export XAUTHORITY="$userhome/.Xauthority"
export DISPLAY=":0"
case $1/$2 in
pre/*)
su $username -c "qdbus org.kde.KWin /Compositor suspend" &
;;
post/*)
su $username -c "/usr/bin/kwin_x11 --replace" &
su $username -c "qdbus org.kde.KWin /Compositor resume" &
;;
*)
exit $NA
;;
esac |
