cpu throtteling

[Ledda]

hi

i'm having some problems with kpowersave on my laptop... it is not efficient. The powersave in kubuntu dapper was much better than this version.
if i set the kpowersave in bianca to :"energy saving" my fans just keep blowing, in dapper they went silent. Is there a way to downgrade?

[Ledda]

anybody with a solution?? its really annoying... my laptop keeps shutting it self out for protection.

i cant find Klaptop to install that instead of kpowersave...


also i have some shutting down problems, i cant shutdown or reboot properly. Have to use powerswitch on laptop.

okay, back on windows, i have like 10 minutes of working time before my laptop overheats and shuts it self down.

in windows i have no problems at all (linux can learn from their powersaving knowledge :p)

but i'm coming to a solution myself: when i do a sudo apt-get install klaptopdaemon i'm receiving a 404 error from the sources.list, some kind of source is down (a feisty source) my internet is up and working. is there a alternate source with klaptop and it deps availeble?

[Ledda]

i've removed mint sources and replaced them with official feisty sources (only to install klaptopdaemon)

i've installed it, but still i cant throttle my cpu speed, i've installe kpowersave en powersaved from feisty but still i cant throttle my cpu speed... (i could throttle it with dapper, what so different so that i cant throttle it now?)

may not be relevant, but if you are running beryl, check
what is eating your CPU,

system->admin->System-monitor

if beryl then look here

Code: Select all

beryl settings manager
    Extras
         Mini-Viewport

if checked, uncheck it, when doing nothing on my system beryl was using 64% cpu
gnome was eating the rest

with Mini-viewport off, beryl uses 0% when not actually doing something

not running beryl.

but thats the problem, nothing is eating from my cpu, because i have no throttle capabilitys the fan just keep blowing at a standard rate, and thats too intensive for my laptop. Because the fan is blowing at high speed, it needs a lot of power, a lot of power causes even more heat, more heat is causing the fan too blow even much harder... its an endless cirkle. When it is getting too hot it shuts itself down.

In dapper i had klaptop, with klaptop i could scale my cpu in 5 steps (525MHz - 1900MHz) But now in mint i have no scaling option, whats so different about mint?

( in kpowersave i see a option "cpu throttling, but it is not highlited, i can not enable it)

Might be worth chance. try installing powernowd, it may remove kpowersave, but my CPU thrittles back nicely with it

that helped a little thx , the fans wont blow at max speed. But still i cant scale it, might there be a chance so i can scale it, just like in dapper?

[Ledda]

this is my powernowd output:

Code: Select all

stefan@ledda:~$ sudo powernowd
Password:
powernowd: PowerNow Daemon v0.97, (c) 2003-2006 John Clemens
powernowd: Found 1 scalable unit:  -- 1 'CPU' per scalable unit
powernowd:   cpu0: 530Mhz - 1855Mhz (7 steps)

hmm i've installed KIMA ( a cpu speed checker) and i see that powernowd is scaling the cpu at it needs. the more load i put on it, the more power the cpu gets.

i think powernowd did the trick.

Have you tried removing Beagle?

[Ledda]

dont have beagle installed on my amd laptop.

When i read trough the topics I've learned that my cpu is scalable.

Code: Select all

userspace powersave ondemand conservative performance


I think that powernowd (that is doing its job fine) is working on "on demand" .

the fans even stopped blowing for a moment, but I'll search further so that i can control my cpu speed manually. (with userspace/powersave/ondemand...)
