On your R14 install, open a 'top' or 'htop' window and tell me what your 'tdepowersave' use is.

By far -- tdepowersave is the top CPU user on my build continually taking more than any other process. This is not right. It is using 2x-3x more CPU than X or kded and is continually at the top of the list. It never stops.

What do you see?

I see dead people. I see dead people everywhere....

I don't see high numbers. tdepowersave is at the top of my top list at about 3%.

Traditionally kmix and knotification-daemon always have been at the top of top too, at about 2%.

I'm sure our tdepowersaverc files are different. Perhaps post your tdepowersaverc. Here is mine:

[General] ActionOnS2DiskButton= ActionOnSleepButton= AlreadyStarted=true Autostart=false AutostartNeverAsk=true batteryLow=4 batteryLowAction=SUSPEND2RAM batteryWarning=10 batteryWarningAction=BRIGHTNESS batteryWarningActionValue=10 lockOnSuspend=false

I don't use the tdepowersave much, even when on battery. Mostly because of bug report 1623. Typically I press Fn+F4 (Thinkpad T400) or close the lid. I'm not a comfortable laptop user anyway. I hate laptop keyboards and trackpads. Right now I use the laptop as my guinea pig with all of the help handbook patching I have been doing. Having the laptop next to me on my desk next to my production system is convenient. I've disabled the trackpad and attached a wired mouse, but I still I hate the keyboard. Generally, laptops suck and I'm amazed at how awful they are designed from a usability perspective yet people use them and then convince themselves they are pigs in mud. :)

You are correct that the CPU use is in the 3-5% range, that in itself isn't the problem. The problem is that it is ALWAYS 3-5% and ALWAYS at the top of the list. That signifies a runaway process in tdepowersave that is not playing nicely. tdepowersave should only require 3-5% of the cpu when it does something, not continually. tdepowersave should only be monitoring input and starting timers, screensavers, suspend, etc.... Those are all negligible and darn sure less that was X is doing. So there is a live Gremlin in tdepowersave somewhere....

Here is my tdepowersaverc:

[General] AlreadyStarted=true

That's it....

Strangely, it does blank the screen at some pre-defined interval, but it is definitely spinning its wheels an awful lot...
