View Full Version : [kubuntu] Power management in Kubuntu 10.10

October 12th, 2010, 06:21 PM
I just did a fresh installation of Kubuntu 10.10 on a laptop last night, which has a 1.6GHz Intel Core Duo CPU.

I was very disappointed to find that there appears to be no way to configure CPU frequency scaling in the System Settings. There were options for this in 10.04.

I prefer to have the CPU running at maximum speed when running on A/C. In Maverick, however, I have had to resort to installing cpufreq-utils, and setting the CPU cores to 'performance' from the command line.

I like this laptop a lot, but even many simple games run sluggishly if the CPU cores are not set to run at max GHz. (As a matter of fact, this machine is much more sluggish even with CPU cores running at maximum in 10.10 than was the case in 10.04.)

I wonder why such an important option would have been removed from the power management settings?

Am I possibly missing something?

I noticed the exact same thing. I created a thread here:

I'll let you know if someone answers my question there!

Sorry that I somehow missed your thread!

I would have just added my post to your thread, had I seen it.

Same issue here and would really like to figure this out. Running VMware with the on-demand CPU governor sucks.
