[opensuse] leap15 - how do I enable display power saving ?

Minimum server install, so no GUI. -- Per Jessen, Zürich (18.9°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
