Basically the same question as asked in
https://askubuntu.com/questions/789846/
I.e., with my recently installed Lubuntu (18.04.2), the system does not suspend after closing lid of my laptop.
sudo systemctl suspend
cam make my laptop suspend, so I believe it is Lubuntu’s configuration issue.
I tried fixing the problem myself by following
http://tipsonubuntu.com/2018/04/28/change-lid-close-action-ubuntu-18-04-lts/
i.e., uncomment the line #HandleLidSwitch=suspend
from /etc/systemd/logind.conf
:
$ grep HandleLidSwitch= /etc/systemd/logind.conf
HandleLidSwitch=suspend
and I’ve restart the Systemd systemd-logind.service
service as well.
But my laptop still doesn’t suspend after closing lid.
Please help. thx
