Version: unspecified (using KDE 4.6.0) OS: Linux When configuring the _Global_ power management settings, in the 'Settings and Profile' page, perform these steps. 1. note the 'Apply' button is greyed out 2. Check/Uncheck "Lock screen on resume". 3. Note 'Apply' button is now available. 4. Change it back. 5. Note 'Apply' button is /still/ available (even though settings haven't changed from their original values.) 6. hit 'Apply' button. 7. NOTE: 'Apply' button does not change. No 'error' dialog. 8. HINT: check .xsession-errors and observe that every hit of the 'Apply' button is accompanied by this error message in .xsession-errors: kded(2715) PowerDevilUPowerBackend::setBrightness: org.kde.powerdevil.backlighthelper.setbrightness failed Summary of issues: 1. failure to apply brightness settings prevents expected use of 'Apply' button 2. no error dialog was generated for failure to apply brightness settings Reproducible: Always
As of 4.7RC2, the "hint" no longer applies, but the rest of the bug does. Still an issue.
Still an issue as of 4.7.0 final. :-(
