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 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.
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.
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?
would ask how to fix this warning that comes when i start my centos 5 virtual machine that run under windows 2003 std, previously it run smoothly with linux centos 5.
currently Centos 5 Virtual Machine ____________________ VMware workstation 6 for windows ____________________________ Windows 2003 STD
previously Centos 5 Virtual Machine ______________________ VMware workstation 6 for linux ___________________________ Linux Centos 5
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.
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.
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!
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?
My laptop is a unibody macbook and has an intel core 2 duo processor. The CPU Scaling Utility never drops below 1.60Ghz. Is this normal? Also. in the ferquency governors, powersave does not appear. Can I install it?
I just update the system, and the cpu frequency applet stop working. I can no longer lock the cpu frequency. Once I click the cpu applet icon, The whole applet just freeze right there. Does not matter if what I do with it. Well, at least I hope some one just offer me a bit help on how to lock the cpu frequency in terminal. Other wise I can not run Folding@home due to cooling issue.

In the Firewall case, once I type in my password, the whole window just went blank. For the cpu applet case, nothing happen, the window ask for password does not show up. nothing. The system log did not have any entry...neither does the crash log. Which there are lot of entry there since I install F12
how to lock the CPU frequency under Fedora 15. I try to run cpufreq comand but the terminal tells me the comand is bad and ask me if I want to install the program. When I click yes. It says the program has already been installed. While I try to use software manager under GUI, same thing happend. Software manager clearly tells me I have not install that program. But once I choose to install, the system tells me all package has been install?
My Notebook CPU has variable speeds from 600MHz to 1.6GHz but since I upgraded to F13 it has not budged from 600MHz.I have already installed the gnome CPU speed widget and even if I set it to "performance" or "1.6GHz" it stays resolutely on 600MHz
The only indication that I can see that there is something odd is the output of acpitool tells me the min/max cpu speeds are 600MHz/600MHz. I don't know enough about the guts of Linux to know if acpitool is defective or if it's just repeating what it was told by something lower down.I will post some hopefully useful listings of some commands run under Fedora 13 and then the same commands on the same box with an F12 live USB.
Code:
Fedora 13 $ acpitool -c CPU type : Intel(R) Pentium(R) M processor 1.60GHz
If I boot my system with default BIOS settings (no overclocking), the CPU runs at 3.3GHz and powernow-k8 enables a maximum speed of 3.3GHz, as can be seen from the following:
[Code]....
Clearly, for some reason, powernow-k8 is mis-calculating the pstate 0 or maximum speed and this is reflected in the files within /sys/devices/system/cpu/cpu?/cpufreq/ I have tried to update /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq, however despite the file being writeable by root, the change is not maintained. Other than setting the CPU policy to "Performance" rather than "On Demand", is there any way I can force the correct pstate 0 (maximum) CPU speed?
My desk-pc has an acer AL17AL17. I've tried to install fedora 12 (windows XP works perfectly) and -just starting- it gave me the message: "frequency not supported". I suppose I have to change it, but I don't know what I should do. The installation began, I selected to do a new installation and then, suddenly, the message. Should I change it in windows? Which frequency do I have to use?
--> On fedora 12: I'm going to install the "Long Term Supported" 6.0 version, as knudfl told me. Anyway, now it doesn't give me that error.
The Wikipedia says that the frequency of the Athlon 64 X2 3800+ is 2000 MHz.
For that processor, on FC 12 64 bit cat /proc/cpuinfo shows: cpu MHz : 1000.000 for each processor.
Is that supposed to "add up" to 2000 MHz for both? My old GA-K8N-Ultra SLI motherboard has its BIOS set for "top performance", so I hesitate increase any clock speed or multiplier.
I have just upgraded my system to Fedora 14. One thing I noticed after running some applications on it is that it is not possible anymore to figure out on what frequency a wireless interface is using. If I set a wireless interface to monitor mode and perform the iwconfig or iwlist command, in the past, I could see the frequency used on the interface, but now, this information is not present anymore. My wireless interfaces are in monitor mode.
Has the frequency information been removed from iwconfig or iwlist commands? If it has, is there another way to report this information?
i have an hp pavilion dv7 and am using f13 64bit. my laptop has a built in woofer underneath that i have never been able to get to work. after the latest kernel update today my laptop now has woofer sound. there must be some new support for my laptops audio card. the problem is that it is a little overbearing. how can i a) disable this feature b) tweak the parameters like crossover frequency or gain? edit: i checked the changelog for 2.6.34 and couldn't find any info on any new audio support features.
Just installed Fedora 13. How do I tell the new "PolicyKitOne" that I should be able to scale my CPU frequency without admin auth? In F12, there was a tool called polkit-auth, but it no longer exists. In fact, when I type in "polkit" and hit tab, nothing shows in the completion menu. Where's this thing hiding?
