A quick questions about Debian

Pazau · 02-18-2009, 05:31 PM

Is CPUFreq or any CPU-program installed by default in Debian 5.0?

And if it is, how do I remove it?

pljvaldez · 02-18-2009, 05:36 PM

Define "by default" (I always do bare installs and then build on top)?

Anyway, to remove it would be sudo aptitude purge cpufreqd. You can see everything that is installed by doing dpkg --get-selections > ~/myselections.txt

No packages will be removed with sudo aptitude purge cpufreqd :S

apt-cache policy packagename will show if that package is installed.

No, they aren't installed by default.
cheers,

You can search packages as well.. for future reference..

Search only installed packages

Code:

it-lenny:~# aptitude search ~i | grep cpufreq
i A libcpufreq0      - shared library to deal with the cpufreq Linux kernel feature

or search all packages

Code:

it-lenny:~# aptitude search cpufreq
p   cpufreqd                     - fully configurable daemon for dynamic frequency and voltage scaling       
p   cpufrequtils                 - utilities to deal with the cpufreq Linux kernel feature                   
v   gnome-cpufreq-applet         -                                                                           
p   libcpufreq-dev               - development files to deal with the cpufreq Linux kernel feature           
i A libcpufreq0                  - shared library to deal with the cpufreq Linux kernel feature              
p   xfce4-cpufreq-plugin         - cpufreq information plugin for the Xfce4 panel

i = installed
A = Automatically installed by aptitude (dependency)
p = Package and configu files purged (package is not installed)
v = virtual package

The library that is shown as being installed, is a dependency for gnome-applets that is why it's on my system..

aptitude command line reference

Or you can just set the governor to "performance" which means it's always at max speed.
/etc/default/cpufreq (or something like this)

Pazau · 02-19-2009, 03:50 PM

With this guide http://technowizah.com/2007/01/debia...anagement.html

I had set it to Performance. But the last to put a line into /etc/sysfs.conf, I can't, that the file does not exist? What should I do?

farslayer · 02-19-2009, 04:00 PM

http://packages.debian.org/search?se...table&arch=any

looks like that file is a part of sysfsutils.. you could install that package to get the configuration file to appear..

nx5000 · 02-19-2009, 04:29 PM

aptitude install cpufrequtils
echo 'GOVERNOR="performance"' > /etc/default/cpufrequtils
reboot

Let the system decide

I can see that cpufrequtils is already installed, in Synaptic. But when I try your command, nothing happen.

Pazau · 02-19-2009, 05:03 PM

I installed the package and the file appeared. But it still not working...

Try /etc/init.d/cpufrequtils restart. Currenty you have ondemand still as you can see
What desktop manager you have? Kde?
