Version: 3.4.2 (using KDE KDE 3.4.2) Installed from: Gentoo Packages Compiler: gcc (GCC) 3.4.4 (Gentoo 3.4.4, ssp-3.4.4-1.0, pie-8.7.8) OS: Linux klaptopdaemon ignores my settings for the power management. It lets my notebook all the time run with the "performance" governor, but it should run with the "ondemand" governor (the battery monitor shows it, and a cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor, too). This is my ~/.kde/share/config/kcmlaptoprc: [AcpiBattery] BAT0=65307 [AcpiDefault] EnableHibernate=false EnablePerformance=true EnableStandby=true EnableSuspend=true EnableThrottle=true [BatteryCritical] Brightness=false BrightnessValue=255 Hibernate=false Logout=false LowVal=5 Notify=true Performance=false PerformanceValue=ondemand PlaySound=true PlaySoundPath=/usr/kde/3.4/share/sounds/KDE_Beep_Beep.wav RunCommand=false RunCommandPath= Shutdown=false Standby=false Suspend=false SystemBeep=true Throttle=false ThrottleValue= [BatteryDefault] BlankSaver=true ChargePixmap=laptop_charge Enable=true NoBatteryPixmap=laptop_nobattery NoChargePixmap=laptop_nocharge NotifyMe=true Poll=20 [BatteryLow] Brightness=false BrightnessValue=255 HaveTime=1 Hibernate=false Logout=false LowVal=15 Notify=true Performance=true PerformanceValue=powersave PlaySound=true PlaySoundPath=/usr/kde/3.4/share/sounds/KDE_Beep_Beep.wav RunCommand=false RunCommandPath= Shutdown=false Standby=false Suspend=false SystemBeep=true Throttle=false ThrottleValue= [LaptopButtons] LidBrightness=0 LidBrightnessEnabled=false LidPerformance=powersave LidPerformanceEnabled=true LidSuspend=0 LidThrottle= LidThrottleEnabled=false PowerBrightness=0 PowerBrightnessEnabled=false PowerPerformance= PowerPerformanceEnabled=false PowerSuspend=0 PowerThrottle= PowerThrottleEnabled=false [LaptopPower] LavEnabled=false NoLavEnabled=false NoPowerBrightness=0 NoPowerBrightnessEnabled=false NoPowerLav=0 NoPowerPerformance=ondemand NoPowerPerformanceEnabled=true NoPowerSuspend=0 NoPowerThrottle= NoPowerThrottleEnabled=false NoPowerWait=5 PowerBrightness=255 PowerBrightnessEnabled=false PowerLav=0 PowerPerformance=ondemand PowerPerformanceEnabled=true PowerSuspend=0 PowerThrottle= PowerThrottleEnabled=false PowerWait=20 [ProfileDefault] BrightnessOffLevel=160 BrightnessOnLevel=255 EnableBrightnessOff=0 EnableBrightnessOn=0 EnablePerformanceOff=1 EnablePerformanceOn=1 EnableThrottleOff=0 EnableThrottleOn=0 PerformanceOffLevel=ondemand PerformanceOnLevel=ondemand ThrottleOffLevel= ThrottleOnLevel= [SoftwareSuspendDefault] EnableHibernate=false
Meanwhile, I've updated to KDE 3.5-alpha1. The problem has gone here.
With KDE 3.5-beta1, the problem is back.
When I change performance governor at shell, klaptopdaemon shows me the change, but I'm not able to set an other governor in klaptopdaemon.
Klaptopdaemon depends on the deprecated kernel feature CONFIG_ACPI_SLEEP_PROC_SLEEP check your kernel config if that is enabled. It should create '/proc/acpi/sleep', so if you havn't that file recompile your kernel.
Ruben, thanks for explaining that ;-) Unfortunately, I wasn't able to create /proc/acpi/sleep by building a new kernel with CONFIG_ACPI_SLEEP_PROC_SLEEP in .config from kernel sources gentoo-2.6.15-r2, but that's ok for me. Now I know the cause for the problem.
Is there a simpler work around, I can't see myself recompiling my kernel over this.
I have personally contacted the KLaptopDaemon author/assigned and he confirmed that the tool is deprecated in KDE SC 4 (replaced by PowerDevil) and that there are no current efforts to support/maintain the KDE SC 3 version. Because of this, I will close the reports as UNMAINTAINED. Regards
