FWIW, no problem here on a HP255G7 laptop with openSUSE 15.1 Plasma 5.12.8 Frameworks 5.55.0 Qt 5.9.7 "Solved" it. It had nothing to do with KDE. It is/was due to some xorg.conf setting, which probably occurred during some Nvidia driver update.
The error information which put me in the right direction was
"The X11 connection broke: Unsupported extension used (code 2)"
I studied the xorg.conf and found a statement
Option "DPMS" "false"
in the Monitor section:
Section "Monitor"
Identifier "Monitor0"
VendorName "Unknown"
ModelName "DELL U2515H"
HorizSync 30.0 - 113.0
VertRefresh 56.0 - 86.0
Option "DPMS" "false"
Commenting the statement out or setting the option to "true" did the trick.
I do not exactly know why and since when the statement happened to be there.
Probably it has to do with a monitor mix in a Xinerama configuration.
Sorry to have bothered you.
At least I have learned that powerdevil needs monitor DPMS.
Thanks for reporting back! However, I think PowerDevil shouldn't die when DPMS isn't available. Originally DPMS was an optional feature in PowerDevil but is now compiled as part of the core set. It checks for XRandR extension in brightness controls but it just unconditionally uses DPMS extension and is then killed when it is disabled. So while I don't think it is a high priority to fix that, given you have to disable it manually in xorg.conf (I believe), imho it should still be addressed. Possible patch: https://phabricator.kde.org/D26219 Git commit 18e53dbaaea261e1e07a75e01955baa7e373071b by Kai Uwe Broulik. Committed on 27/12/2019 at 09:04. Pushed by broulik into branch 'Plasma/5.17'. Check for DPMS extension being present It might be disabled. Don't die in this case.

After an Opensuse Leap 15.0 to 15.1 upgrade enegry saving functionality is no longer available in KDE5 Plasma. systemsettings 5 does not give you the possibility to configure - and power saving is not available as a KDE background service. This is user independent. upower.service is running.
