Ubuntu :: CPU Frequency Scaling Not Working

Jan 17, 2010

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.

Fedora :: 13 - CPU Not Scaling Frequency?

Jun 16, 2010

I 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


I notice here that it says between 800 and 800, but does that mean it is currently at 800, or can only be 800.

Ubuntu :: CPU Frequency Scaling Monitor & Hyperthreading?

Sep 2, 2010

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.

Ubuntu :: CPU Frequency Scaling Always Enabled - How To Disable

Nov 19, 2010

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.

Slackware :: Activating Cpu Frequency Scaling ?

May 15, 2011

Slackware64 13.37 multilib, generic kernel (full install)

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.


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.

Ubuntu :: Set Cpu To Powersave Using CPU Frequency Scaling Applet - Set Permanently?

Oct 13, 2010

Trying 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.

Ubuntu :: CPU Frequency Scaling Monitor Doesn't Work?

Jun 1, 2011

I have recently installed Ubuntu 11.04 on my PC with these configuration:CPU: AMD Athlon 7750 Black EditionRAM: 2GB 1066 MHzVGA: ATI Radeon HD 3200 (on AMD 780G)After I installed Natty Narwhal I felt that my CPU runs at the highest clock all the time (2.7GHz), even if I don't have any program run. I tried all settings for AMD Cool'n'Quiet from mainboard BIOS, but nothing's changed. I installed "CPU Frequency Scaling Monitor" to manually change CPU clock. It recognizes two clock for my CPU, 2.7GHz and 1.35Ghz plus 4 other options; Conservative, Ondemand, Performance and Powersave but the CPU indicator doesn't change on every option!

Slackware :: 13.37 Isn't Loading The Modules - CPU Frequency Scaling ?

Jun 10, 2011

For 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?

Slackware :: CPU Frequency Scaling Will Not Load At Boot

Nov 16, 2010

I'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:


And below the "### CPU frequency scaling policies:" i have;


uncommented. My scaling governor is set to:


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... ?

Debian Configuration :: Disable CPU Frequency Scaling In Most Fundamental Way

Jan 18, 2016

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.

Ubuntu :: Overclocked CPU And Ubuntu Frequency Scaling

Aug 5, 2010

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?

Ubuntu :: Possible? /temp/www/fake/ Contents (directory) Avaliable Through /temp/www/?

Dec 20, 2010

I have a web server whos DocumentRoot is:/tmp/wwwNow, /temp/www/fake/ is a directory that contains a series of other files/folders.What I want to do is access the files in /temp/www/fake as if they were in the root directory (/temp/www/)For example:

could either be located in "/temp/www/test.php"
located in "/temp/www/fake/test.php"

so "" would essentially call both directories. Is this possible? Whould I do this through apache or through the actual file system somehow? (Like some sort of symbolic link?) I would love to hear your input.

Ubuntu :: Disable CPU Scaling Whenever Want?

I have tried the following on 9.10 and 10.04 (both amd64). I use rcconfig to disable "on demand" (from [URL] but then when I use cpufreq-info tool I get:

Ubuntu :: 10.04 - BIOS Does Not Support CPU Scaling

Jun 26, 2010

I've been trying to get lucid to work on my gateway netbook. The major problem I've seen is that it would overheat (to about 63 C or a little higher, and then the display would go crazy and crash. My BIOS doesn't support cpu scaling. Somewhere in a google search, someone mentioned the 2.6.34 kernel. I had no ideal what I was doing, and I installed this kernel. (could not install headers -- a dependency issue I didn't understand). Tried it, and it booted.

Saw some errors, like timer or something not found and something about a soft reset. However, it boots, and it works, and the temperature is much better (at least for the last 42 minutes: I've not been able to run it that long before). Are those errors likely to cause problems? Are there any issues I should be aware of using a non-standard kernel like this? I am dual booting with 9.10, which works well, and all my serious work is on the 9.10 partitions.

HID compliant mouse
Synaptics PS/2 Port touchPad
Generic PnP Monitor
Atheros AR5B95 Wireless Network Adapter
Realtek PCIe FE Family Controller
AMD Athlon(tm) Processor L110
Realtgek High Definition Audio
Microsoft iSCISI Initator
Gateway LT3103u

As I write, temp is still at 56, but I am getting some intermittent display problems. Should I give up on lucid?

Ubuntu :: CPU Speed Scaling For AMD 1090T?

Oct 15, 2010

I'm running ubuntu 10.10 64 bit. CPU speed scaling says my CPU (AMD PhenomII 1090T) is not supported, and shows full speed on all cores, regardless of load. I've read that those issues were solved in kernel 2.6.34...

How can I make it work? or do I have to wait for an update?

Motherboard is an ASUS Crossfire IV.

Admins: Feel free to shift this post to another (sub-)forum if necessary, I wasn't sure where to put it.

Ubuntu :: Smooth Image Scaling In FF3?

Oct 24, 2010

i face problem with Firefox 3.6.11: smooth image scaling doesn't work. When i zoom in websites (ctrl +), images are not anti aliased, but appear pixelated, which is very ugly.

What I found out about so far, this seems not to be a FF problem (FF3 should support smooth image scaling), but a problem with the video driver, who tells X it could do smooth image scaling automatically but it cant. There is also a "bug" fix for the FF:

launchpad.net/~firefox-smooth-scaling/+archive/ppa I putted this to my package sources and made a system update. But smooth image scaling still doesn't work

Ubuntu :: Set Cpu Scaling To Ignore BOINC?

Nov 2, 2010

I am trying to set up my cpu freq. scaling to ignore BOINC. From what google has shown me this is done by setting a value of 1 for ignore_nice_load. However the location of said value does not seem to be the same in 10.04 as in the results from google. How do i set this or is there a better way to keep idle processes like BOINC from increasing the my cpu frequency?

Ubuntu :: HP G60-120US Processor Scaling?

Dec 31, 2010

Basic Info: Ubuntu 10.10, AMD RM-70 2GHZ Processor, HP G60-120US, Bios F54. I'm unable to scale my processor (either core) using the applet in the menu bar. Every time I try, I select 2GHZ, and re-open; then it's displayed that 500MHZ was selected. I'm unable to pick any speed, the computer has a mind of it's own in that sense. It's essentially stuck at 500MHZ for 98% of the uptime, which makes it impossible to do anything more than web browsing. Ex: I tried watching an HD video, I watched 5 min, and 1,400 out of the 10,000 or so were dropped!

Ubuntu Multimedia :: Can't Get GPU Scaling Method To Save

May 18, 2010

I managed to half fix my earlier problem of being unable to clone my desktop monitor to my TV. I set the configuration to TwinView, and the resolution to the same as my desktop (Doh) and that seemed to at least get my desktop the way it used to be.

The problem now is the TV. It's cutting off a lot of pixels, and I can get it almost to fit if I enable flat panel scaling and set GPU Scaling Method to "Centered". However, when I restart the X server, it always returns to "Stretched". I've tried saving it from nvidia-settings (nothing seems to happen to the xorg.conf file,) and ala [URL] s have tried to put some version of

Option "FlatPanelProperties" "DFP-0: Scaling = Centered"
Option "FlatPanelProperties" "Scaling = Centered"
