Linux: Sleep

Common problems

Laptop is not going to sleep

First, check if there are any errors from the suspend service:

systemctl status systemd-suspend.service

If “device is busy”, or “failed to suspend”, check if there are any suspend inhibitors active that you may not want

systemd-inhibit --list

Additionally, if you are using an NVIDIA graphics card, make sure the services that manage the card’s sleep are enabled. If they are not, then the device cannot be put to sleep and systemd crashes

sudo systemctl enable nvidia-suspend.service
sudo systemctl enable nvidia-hibernate.service
sudo systemctl enable nvidia-resume.service
