After upgrading nvidia-drivers to stable version 378.13, hibernate doesn't power off. I have to use power button to end the hibernate process. And when I power on, resume works fine. I find only one error in /var/log/pm-suspend.log : sam. avril 1 12:40:19 AST 2017: performing hibernate /usr/lib64/pm-utils/pm-functions: ligne 323 : echo: erreur d'écriture : Argument invalide sam. avril 1 12:41:11 AST 2017: Awake. sam. avril 1 12:41:11 AST 2017: Running hooks for thaw Downgrading to x11-drivers/nvidia-drivers-375.26 solves the problem and all works fine. So I just masked =x11-drivers/nvidia-drivers-375.39

I had exactly the same problem with another PC when I updated nvidia-drivers to 378.13 The line 323 of /usr/lib64/pm-utils/pm-functions is : echo "$HIBERNATE_MODE_SAVE" > /sys/power/disk with HIBERNATE_MODE_SAVE set to "platform" I decided to try with lastest x11-drivers/nvidia-drivers-381.09, but not better. After searching and reading https://askubuntu.com/questions/895593/cant-set-hibernate-mode-shutdown-in-etc-pm-config-d and https://askubuntu.com/questions/767679/ubuntu-16-04-doesnt-shut-down-after-suspend-or-hibernate/837334#837334 I created : # cat /etc/pm/config.d/hibernate_mode HIBERNATE_MODE="shutdown" And now, even with x11-drivers/nvidia-drivers-381.09, hibernate can now shutdown correctly. I don't understand why it works like that now, and I didn't need it with <x11-drivers/nvidia-drivers-378.13, on 2 differents PCs. PS : sorry for my bad english.
Considering this happened with the last-rited pm-utils and nvidia-drivers made many changes regarding power management since, I'll assume this is obsolete. Glad managed to find a workaround back then still.
