Power Management configuration module could not be loaded


#1

Since a couple of weeks when I go to Settings; Power Management, I get the message “Power Management configuration module could not be loaded”. I’m also missing the Suspend button.

I did some investigation on the internet, but was not able to solve the issue.
I’ve done a purge and install of upower and of powerdevil. Also sudo apt-get update and upgrade did not solve the issue.
With “ps -e | grep power” I only see the powerd and kworker/2:3-events_power_efficient running
With “journalctl | grep power” I get:

I need the server to be able to go to suspend when there is no activity. Who can help?
