Using Tumbleweed with KDE6.
When I want to activate power profiles from the tray it does not succeed with “Failed to activate power-saver mode” message. Additionally Power-profiles-daemon has an error:
failed to update driver intel_pstate: Error writing '/sys/devices/system/cpu/cpufreq/policy6/energy_performance_preference'
Previously it was working with KDE5 and as I remember also with KDE6 for some time. What can be the problem?
