I want to turn off frequency scaling permanently and totally in the lowest-level way possible. Is there a kernel command line that can be used or is recompiling the kernel without the governor stuff the only way?
Solved. Just modprobe -r and blacklist the acpi_cpufreq kernel module.
When I boot my machine (using a dual core 2ghz CPU) I always find myself out of "performance" mode (which I need), using only 1ghz per core.While this is easily fixable with "sudo cpufreq-set -g performance", I don't seem to be able to do it before having control of the machine. I would like to be able to boot with my CPU at full power.I would prefer to disable whatever is scaling down my CPUs to having to inject cpufreq-set to change governor. Anyone has any hint?I use default Ubuntu but I boot into a KDE4 desktop. But the same issue happens booting into the Gnome desktop.
View 9 Replies View RelatedI'm having a weird problem (2.6.32-2-686-bigmem , sid):
Frequency scaling works on CPU 1 but not on CPU 0.
This is regardless of application, the Gnome applet and cpufreq-selector both fail
I have a suspicion that this is easily fixed, however a good google (and this forum) hammering having turned up the fix. So I probably have the wrong search criteria, My Gnome Applet for switching CPU Frequency Scaling has 'disappeared' and is not listed in the the Add to Panel.. list of applets.
View 3 Replies View RelatedI am not entirely convinced that my CPU is actually changing frequency as it is meant to. It sometimes changes frequency, but most of the time it is stuck on 800MHz even when doing cpu intensive tasks. Here is information that may or may not be of help:
cat /proc/cpuinfo
processor: 0
vendor_id: GenuineIntel
[code]....
I notice here that it says between 800 and 800, but does that mean it is currently at 800, or can only be 800.
I have the CPU frequency scaling applet in the panel and it worked fine when I had 8.10 but now that I'm using Karmic, I cant get it to work correctly!
It won't change the speed to what I tell it to. I click on a different speed and it does nothing.
The CPU spins too slowly and videos lag or it spins at full speed and overheats even though I have nothing open! I really need to be able to adjust it.
I am new to ubuntu. I have just one question, everytime I reboot my laptop the CPU Frequency Scaling Monitor goes back to "On Demand." Why is that and can I also set it so it stays on Performance.

BIOS: EIST and C3/C6/C7 State support are enabled.
I'm trying to activate cpu frequency scaling following the tutorial on slackwiki: [url]
I can't load any module.
Code:
I've tried all of them but the error is the same. I also rebooted to the huge kernel, however, it gave me the same error.
I recently installed 10.04 and really like it so far, however I was wondering if it is possible to scale all hypertheading cores at once, currently I am using an applet for each and have to use several clicks to get into the desired powerstate.
I have read that with dual cores you will not have the option to go into different powerstates because it scales all cores at once, however the logical cores that show up with hyperthreading allow each to have a different power state, and will show up as different states if I use cpufreq-info in the terminal, so it seems like it is allowing it.
Is there an easy way to take control of CPU frequency scaling in 11.04? There use to be an indicator applet but thats gone
View 2 Replies View RelatedFor some reason, it seems that 13.37 isn't loading the modules I need for cpu frequency scaling. I've edited /etc/rc.d/rc.modules so that CPUFREQ is set to on. On 13.1, this would mean the powernow-k8 module would be loaded for my AMD cpu, and the subsequent "ondemand" governor would be loaded. However, for some reason this isn't being done during the boot process. I've tried it using both the generic kernel and the huge kernel (I'd been using huge for a long time before without realizing it.) Has anything changed in 13.37 with regards to CPU frequency scaling?
View 5 Replies View RelatedI'm curious as to why some things are not happening at boot time (i end up having to manually load them).
In /etc/rc.d/rc.modules (near the bottom) i have set "CPUFREQ=on" and commented out any modules not specific to my hardware.
I have left this one uncommented:

Now whenever i reboot my machine `lsmod` is not showing any of either powernow-k8 or cpufreq* related modules.
I know i could use /etc/rc.d/rc.local with these:

But seems to defeat the purpose of rc.modules, any idea why they are not being loaded at boot... ?

Is there any possible way to keep my CPU frequency scaling on PERFORMANCE mode through a reboot? Ubuntu likes to default it back to ONDEMAND all the time.
View 5 Replies View RelatedTrying to set my cpu to Powersave using the CPU Frequency Scaling applet. When I set it to powersave, it goes back to ondemand on its own. On the earlier versions of Ubuntu, I used to be able to set it from the main menu: system>powermanagement, but with 10.10, I don't get that option. Is there any way that I can set it to powersave permanently? I was also able to set it with Ubuntu Tweak, but it does not have that option either.

I have a 2.9ghz AMD Athlon II X4, which I have overclocked to 3.65ghz. I know that Ubuntu automatically changes the frequency of the processor to save power, which I like, but it does not show my overclocked frequency. The highest that the frequency scaling will go is the stock clock, at 2.9ghz. Is my processor actually reaching my overclocked speed?
View 4 Replies View RelatedI recently deleted all my Software Sources that were under "Other Software" and all my "Authentication" because Mint kept updating my xulrunner to a new version which would disable Firefox-Smooth-Scaling.Therefore I deleted all my Software Sources that were under "Other Software" and Authentication, and forced Mint to only install the xulrunner which uses Firefox-Smooth-Scaling. Unfortunately, after I deleted the software sources and authentication, now I can't update my system properly and get error messages that keys are missing. I added some software sources back the "Other Software" (someone responded to a previous post of mine on which ones to add), and under the "Authentication" window I tried hitting "Restore Defaults", but it only added two keys. These are screenshots of my Software Sources windows.

Howto disable IPV6 in Lenny?
I added this line:alias ipv6 off in /etc/modprobe.d/aliases:# cat /etc/modprobe.d/aliases
# These are the standard aliases for devices and kernel drivers.
# This file does not need to be modified.

# Please file a bug against module-init-tools if a package needs a entry

alias ipv6 offbut howto check after restart if ipv6 was loaded or not?
I've been using Debian since the early days of Lenny being testing as OS on the same Computer. Its a Acer Aspire Notebook with switches for wireless and bluetooth. While booting Lenny my wireless and bluetooth stayed off as long as I didn't switch them on. But since squeeze they get activated ( you can see it by looking at the LED's ) the moment after the grub screen. I now do have to turn bluetooth and wireless off by hand everytime which is quite annoying since I mostly use eth0.
how to disable bluetooth and wireless per default in a way I can simply turn them back on by using the switch?
So from a web server stand point if we start using swap for httpd or mysql its bad and performance goes down the drain. So would it be a good or bad idea to disable swap entirely?
