Ubuntu :: CPU Frequency Scaling Monitor Won't Stay At 800mhz After Reboot Or A Certain Period Of Time
Oct 26, 2010
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 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.
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.
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.
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 am useing a PC as a simple display and I need the monitor to stay on for long periods of time. I have set the power saving setting to "presentation" mode and it is not supposed to turning the monitor off. Is there somewhere else I need to adjust this??? I am running OpenSUSE 11.1.
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 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:
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.
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.
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?
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 know that this has been a frequent discussion post and I have read a large portion of the posts but none of them have fixed this problem for me. My computer seems to default to performance upon reboot (and yes I have waited the 60 seconds it should take to switch to ondemand). I have tried a number of the ideas posted throughout the web but have been unable to set the default upon reboot. Here is my current /etc/init.d/ondemand script:
Code: ### BEGIN INIT INFO # Provides: ondemand # Required-Start: $remote_fs $all # Required-Stop:
I installed ubuntu 10.0.4 TLS version and my desktop freezes after a period of inactive time: the screen doesn't change and the apps do not response. It will resume after any key-stroke or mouse action. Is it a feature of 'power-saving' or something else? I need my ubuntu keep 'alive' all the time.
Now i am writting one bash script. in that my requirement is i need to create one directory and that the directory details to be stored in one file Ex. date/time and all in one file. after that i need to delete the folder automatically exactly after 3months. between these time period in 2month itself i need to send one mail to admin "regarding this still one month only more to delete the folder" . is it possible to do like that date calculation in script.
I'm using Ubuntu Netbook Remix 9.04 in Acer Aspire One together with Windows XP (both on different partitions). The trouble since installing Ubuntu has been that my keyboard has scandinavic layout which includes "" and "" keys. When I assign the layout in Ubuntu's as "FI" instead of "USA" everything is fine. After reboot for some reason the changes made won't stay and I have to change the keyboard layout manually. If I remove "USA" from the list after reboot it'll appear to the list again!
I've tried to create /etc/X11/xorg.conf file with the keyboard configuration code, but it has no effect for the situation. I've tried also command:
Code: sudo dpkg-reconfigure console-setup This has no effect also.
I'm starting to be frustrated for the situation. I really enjoy using Ubuntu instead of XP but this just doesn't make sense that the keyboard layout won't stay on.
I'm using Nvidia's driver from their website and Kubuntu 8.04. I tried Debian 5.04 kde on the same computer and the resolution stays. Of course I prefer kubuntu. After shutdown the video resolution goes back to 1024x768 but I want 1280x800 instead. I have a Dell IN191ON lcd widescreen monitor and geforce fx 5200 video card. I'm using the latest video driver from Nvidia for this card version NVIDIA-Linux-x86-173.14.25-pkg1.run.
Here is my xorg.conf.

I just reinstalled, and can't get the setting set right so that my display does not shut off after a certain period of time. It is shutting off after a while of inactivity, and I do not want it to.
I currently have fedora 15 installed along side windows 7 on my acer aspire d250. So far it runs great, however I was wondering if there is a way to make fedora 15 hibernate after being in suspend for a period of time, just like windows 7 does. This make sense to me as there is no point in wasting battery life if i can hibernate, but I don't want to hibernate all the time, just suspend for a period of time, like 2 hours, in case I need my netbook again i have quick access to it.
I'm trying to block a site for a certain time.How to Block(deny) perticuler website in certain times of the day , by using squid ? and it seemed promising.I added the lines to my squid.conf
acl office_time time MTWHF 3:00-21:00 acl bad url_regex "/etc/squid/block.acl http_access deny bad !office_time
created a block.acl in the same directory and restarted it.
