[SOLVED] KDE poweromanager not working after resume.

Using KDE on arch linux.

Power manager works after boot, and PC goes to sleep after a while. But after resume, power manager doesnt't work any more.

KDE power manager after resume shows:

Power Management settings could not be loaded

The Power Management Service appears not to be running.

upower service is running.

Re: [SOLVED] KDE poweromanager not working after resume.

Hello o/

This is a problem caused by the "ddcutil" package in version 2.2.0, it has been reported that it will be fixed in the next version. (Source: https://bugs.kde.org/show_bug.cgi?id=500843)

What you can do like I did is downgrade ddcutil to version 2.1.4 using the archive (https://archive.archlinux.org/packages/d/ddcutil/) and ignore the package update editing pacman.conf until next update OR
build version 2.2.1-dev yourself.

Thank you! I downgraded ddcutil as well.
