Ubuntu :: Cpu Frequency Governor Stuck
Feb 4, 2011
I'm using the latest kernel and after I boot up my computer the cpu governor changes from the fastest setting (2ghz) to the slowest setting (800mhz), and gets stuck there. Theres no obvious way to change the setting, the gnome applet to change the cpu frequency doesn't work - I've also tried to change the setting manually through the /sys/ directory but to no avail.
There was a suggestion to fallback on an older kernel, but my older kernels suffer from the same bug.Does anybody have any ideas? I can provide more information on request.

Whenever I unplug my laptop it gets slugishly slow, and I don't understand why. I noticed that when on battery I cannot by any means make the cpu work at its full speed (1.7Ghz) even with the performance governor; it always stays at 1.2Ghz. When unplugged from AC, cpufreq-info also tells me the speed can vary between 600MHz and 1.2Ghz, even though it reports the max hardware speed of 1.7Ghz. Besides, I have tested the laptop on AC power at 1.2GHz and it seems a whole lot faster than when on battery at the same speed. Are there any more "power-friendly" reductions in... say for example, graphics card? It would impact UI redesign significantly (and it sure as hell looks slow). How can I customize (or at least disable) these inconvenient cpu speed reductions?

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

I want my computer to use the "ondemand" CPU frequency scaling governor when plugged in and switch to the "powersave" governor when running on battery power.

I have issue with cpufreq frontend in LXDE, I cant change governor. I am in powerdev group. Maybe I dont have permission to change governor with this plugin. I am using Debian Squeeze. Please what can I do, I can change the gowernor: cpufreq-set -g ... , but I want to do that like normal user in cpufreq frontend in LXDE.

On an asus p4C800, i have a, very old, pentium 4 3.2 GHz (HT, prescott). On which i installed an opensuse 11.4 (after some network quirks and some grub tricks)... First i saw that the p4_clockmod module was not compiled for the kernel. It took me one night to compile the modules, and it borked my whole installation, which i spent my day to remake, but that's another story. After loading all the appropriate modules (speedstep-lib, cpufreq-something, etc...), i run this command :

I have a n2pap-lite motherboard with a AMD Sempron 2800+. My host clock is at 133mhz when it needs to at least be at 166mhz to be a AMD Sempron 2800+... I installed the system on 100mhz clock not thinking that it mattered.
I tried the following
sudo apt-get install rcconf
sudo rcconf
*Disabled "ondemand"
It says on guides that it will ask me to reboot but it doesn't, so I manually did it and put the CPU Frequency Monitor on my taskbar. It does not have the options like it shows in the screenshots to set my CPU frequency..

I'm looking for a CPU frequency applet which monitors the frequency of ALL CPUs at once.
Does it exist such applet?

I'm running ubuntu 11.04 with a Pentium T2060 1.6ghz. Ubuntu only lets it go up to 1.2ghz. And no its not a cpu power saving feature. In Windows it gets to 1.6ghz fine

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 have edited /etc/logrotate.conf to include
/var/log/auth.log {
rotate 6
monthly
copytruncate
compress
}
To try and prevent auth.log rotating daily and change it to monthly but it doesnt seem to work.
Either im doing it wrong or i need to restart some service?

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'm a bit new in Ubuntu, but I am about to get a hang in it. I have previous use karmic koala and the version before that (cant remember the name for that) on my old computer and now I am using ubuntu 10.4 on my new computer. Ever since I installed Ubuntu for the first time, I noticed that the sound quality wasn't... the best. There isn't so much wrong with it, but like that this example. I played a FLAC file with some headphones (thru Ubuntu) and the sound quality sucked.. and then I played a mp3 file (with an ipod) and the sound quality was much much much better than the FLAC file.
I tired to play an HD movie over ....., where on Windows XP it sounds perfect, but with Ubuntu it kinda sux. The MP3 (Ipod / windows XP) is still better, than anything that is being played in Ubuntu. This is with almost every sound format I have tried. No matter if I play it with Rythmbox or vlc or some other player, the sound is wrong. I cant describe how it sounds.. but it is like it is going with a low frequency... or it is compress some how... Ever since I tried Ubuntu for the first time Ive noticed that something was wrong, but couldn't never really put my finger on it. I have dual-booted with windows XP and the sound in XP is really, really good compared to Ubuntu.

I am doing a project on how power consumption of a CPU can be improved by underclocking the lower P-states and overclocking the highest p-state.In this way you can increase both the performance of the chip and it's average power usage (assuming you don't run the chip at 100% 24/7).
To do this project I need to be able to change the voltage and frequency of the chip for all of the different p-states of the chip. On Windows I can use k10stat, RMClock or AMD Overdrive.
What can I use in Linux? I found k10ctl, but it always complained about not being able to find /dev/cpu/0, so I looked in /dev and noticed that their isn't even a cpu directory in there!
I have a moderate amount of experience so I don't mind changing kernels or doing other hard tasks to get this to work.

A week ago, after some daily update, my cpu frequency monitor stopped working, i'm stuck with 800 mhz now Yesterday i upgraded to 10.10 version, but this applet still doesn't work. or maybe there are alternative programs that change cpu frequency as well? I was looking in software center, but found only monitors so far.

I'm not sure if this is an issue with Ubuntu or with the BIOS. Basically when I start up my computer, the ondemand governor seems to work just fine (ranging from 800 MHz to 2200 MHz). However after some indeterminate amount of time, it will get stuck at 800 MHz and I'm not able to figure out how to get it to scale properly again.
When I restart my computer, it acts normal again for some time before locking in at the lowest frequency.
It seems like it may be related to this post: [URL]. The last post in that thread mentioned that it could be related to the temperature, that may be the case in my situation. Even if the temperature is low after it locks to the lowest frequency, it won't increase the speed as needed
My question is, is there any way to override this and let the CPU continue to run at higher frequencies once it locks down to the lowest frequency? My computer doesn't feel like it's getting that hot (it's a laptop), and I'd like to not have to be able to restart it every time this happens.

I've recently reinstalled a computer with 10.04 for my parents to use, and it worked fine at mine, but after transporting it to theirs and hooking it up to their existing monitor it doesn't seem to work anymore!Well, it boots and I hear it login but I don't get a splash screen and at some point between the bios and the login sound it comes up with Frequency out of Range. On the warning message it displays a frequency of "72.9 kHz / 90.2 Hz" but in the monitor settings its reporting that its operating at horizontal 64,0 kHz and vertical 60.0 Hz. I also don't get any splash screen when starting up, just a flashing _ before the monitor stops things
What I can do however is drop into a the tty console (alt+ctrl+1) and login to the shell but don't really know what things to change from there.Having googled things a bit I've found references to xorg.conf but there's no such thing on my system so I can't edit that to fix this. Likewise I also have found references to fiddling with grub to get into the recovery, but grub doesn't even appear when I boot and I don't know what to press to get it to drop into its menu...
This is really urgent as I need to go home tomorrow at the latest and I want to get my parents system working before then. I also have no spare monitors here and I didn't think to bring with me a liveCD to fiddle with things (only a UNR netbook which I'm posting this from), so the console is the only access I have to the machine.Some specs: Ubuntu 10.04. ATi Radeon 9100 IGP, no proprietary drivers are installed. The monitor is an old CRT that still works beautifully and whose replacement is not an option.

I havent used ubuntu since intrepid, but came back from arch linux excited to try lucid
After I've burned the live cd, I can get to the menu (try ubuntu, install etc), but whenever I try to start ubuntu the frequency goes out of range.
I have tried adding vga=771 to the end of the boot line, this had no effect.
EDIT: Am downloading the alternate now.

I am running Ubuntu Netbook Edition 10.04 on my netbook.
I noticed this version has the ability to switch between desktop environments such as Gnome Desktop and the Netbook Edition UI. When I am in Gnome, I really love using CPU Frequency Monitor available for the Gnome top panel.
My question is: Can I use the CPU Frequency Monitor in the Netbook Edition? If so, How?

So, the only way to have bass is to use PulseAudio and edit daemon.conf to enable-lfe-remixing? Well, damn, but alright. how do I fine-tune low frequency reproduction (since my satellites can't handle anything below 150Hz)?

I am a sound engineer trainee and I'm desperately looking for a Linux version of the Simple Feedback Trainer [URL]. It's a rather easy but very good program that provide info to sound engineers train the detection of feedback frequencies. Do you know if such a thing already exists? I haven't been able to find it in the Ubuntu Software Center.

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.

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
