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:
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.
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.
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.
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!
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?
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.
I just bought asusn a50ij and of course I installed ubuntu, now I have few problems: when I try to add CPU frequency scaling monitor to panel it says: CPU frequency scaling unsupported Next problem:my cpu temp is 49 without any reason.and I cant see my graphic card temp,when I go to Harware Drivers I doesnt show any drivers at all,so I dunno whether its nvidia or raedon it doesnt say anything! Also I installed jupiter and each time I turn on my computer it goes to Maximum Performance how can I turn it off?
The CPU frequency scaling monitor won't stay at 800mhz after reboot or a certain period of time. My goal is to always have my dual core CPU locked at 800mhz to have it run cooler. I'm running Ubuntu 10.10 on my toshiba u300 laptop.
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.
I am using Intel Xeon X 3440 processor. The processor has 11 frequency steps to chose from. I have used cpufreq-selector for choosing a frequency and it worked fine. But, all of a sudden it stops working out of the 11 steps i can change to only 2 frequencies and rest fail to work. I am clueless as to why it stopped working suddenly.
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?
I had it in mind that Ubuntu ran disk checks every 30 boots, but mine are more frequent - running between 10 & 25, which is an irritation. Records show checks after: 12-21-10-20-10-20-13-25-16-21 boots. Should I worry about either the frequency or the variability? I found threads suggesting how to change the frequency using tune2fs, so I suppose I can try that to stretch the interval to maybe 50 or weekly? Will it have any effect, since there is so much variation already? Is there a GUI for setting this frequency, instead of fiddling in terminal?
I don't know how this happened, but my keyboard copy and paste functions have stopped working. Oddly enough, I discovered that I can only copy and paste by using the third mouse button. Pressing down on the scroll wheel after highlighting text copies the text, pressing it again pastes it Ican still use the Edit-copy and Edit-paste menu functions.
I'm sure it has something to do with all the tinkering I have been doing with my desktop. I have been experimenting with CompizConfig and Cairo dock, changing my themes and things of this nature.
I want to be able to disable CPU scaling, whenever I want. The reason is that I run some timing tests, and I want the results to be reproducable (ie the CPU running at the same frequency). 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:
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.

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

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
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?
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!
Since the new Unity in Ubuntu 11.04 doesn't work with applets, like GNOME, I've lost an useful applet to choose the operating clock of my CPU as well as power profiles (Performance, Conservative, On Demand etc.).
I've looked into Ubuntu Software Center but couldn't find anything similar.
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
