CPU Policy (CPU speed scaling) problem...

[hcadavid]

Hello friends,

I'm using kubuntu 7.10 on a DELL c610 laptop (1.2 GHz PIII, 512MB RAM). After solving some post-install problems like sound (I uninstalled ALSA and installed OSS) and NTFS external drive recognition, my system finally worked right. But recently, I noticed a performance problem... while moving my mouse, the systems freezes for a couple of seconds and then continues with it movement ??? ... but when I changed the CPU policy to powersave or performance (constant lower or higher CPU speed) the problem disappears. I've discovered that just by moving the mouse (without any other application running) the system increases and decreases CPU speed (I don't know how many times)... What can I do? >:( now I'm forced to always set manually my CPU speed!!!

best regards,
Héctor

I've been having the same problem. This worked for me:

K > System > Adept Manager
type in your password
type "kpowersave" in the top search box
install it

After installation:
K > System > kpowersave
a green battery appears in the lower right next to the clock
click the battery icon to launch the settings window
In the "Mains Powered" section, look for:
"CPU frequency scaling policy", select "Performance"
Select "Apply"

I also set the "Battery Powered" section to "Powersave"

That solved my problem, hope it solves yours too :-)
