This is known upstream issue https://bugs.kde.org/show_bug.cgi?id=454161 https://bugs.kde.org/show_bug.cgi?id=455308 https://bugs.kde.org/show_bug.cgi?id=455307 Workaround that works for me. Snapper required: * Rollback with snapper to previous version of Plasma * Lock powerdevil5 with zypper sudo zypper addlock powerdevil5 * Update rest of the system The workaround is to keep powerdevil5 in version 5.24 *** Bug 1200543 has been marked as a duplicate of this bug. *** I meant The workaround is to keep powerdevil5 in version 5.24.5 Next workaround: Install patched version from: https://build.opensuse.org/package/show/home:lemmy04:branches:KDE:Frameworks5/powerdevil5 About the workaround, if I follow the link and click "Download package" I get the following error: No data for home:lemmy04:branches:KDE:Frameworks5 / powerdevil5 (In reply to Brutus from comment #6) > About the workaround, if I follow the link and click "Download package" I > get the following error: > > No data for home:lemmy04:branches:KDE:Frameworks5 / powerdevil5 On the right in the Build Result section click your distro, you will be redirected to the latest builds.
