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.
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 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!
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 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.
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.
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?
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'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 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?
I just updated my Wubi install of 9.10 to 10.04 last night. Everything went well until it required me to reboot the computer. I rebooted, loaded Ubuntu from the startup list, and then the screen went blank and I got "H.V. frequency over range" on the monitor.
I can load the GRUB options, but recovery mode using the most recent kernel does not work. I am entirely unexperienced with using the terminal and command prompt options.
Here's what I have attempted so far:
$ sudo dpkg-reconfigure xserver-xorg this did not do anything, the command was not recognized
$sudo nano xorg.config I don't even know what to do when I get to this screen
I have bought a new motherboard (MSI 785GT-E63). I already have an old CRT monitor connected to it. After I install a linux OS to it, my monitor will display that it is:
Out of frequency. Current frequency is 89Hz. The operating output of my monitor is (around) 60-70Hz.
I would like to get this thing work. How can I let my CRT display properly?I was thinking of lowering down video frequency output of my motherboard, but I can't find any settings on my BIOS setup. Additional info:
My monitor is attached directly to the built-in video adaptor of my motherboard. (No additional video
I certainly do not consider myself a Debian power-user, but I do presently have 3 Lenny systems and 1 Squeeze system running fine in my home on "older" hardware. However, for the past week I have been trying to get yet another system running, and I have hit the wall. This is on a new home-built system with an AMD Athlon II X4 and an ASUS M4A785-M motherboard. The Lenny installation was done with a net install of the AMD64 variety.
I always get a "Monitor frequency out of range" error whenever I boot. I can do a CTRL ALT F1 to get to command line, but I have no success getting to GUI. I have read numerous posts of similar monitor frequency problems with various distros, and most point toward HorizSync, VertRefresh, etc settings in xorg.conf. I have played with a myriad of options there, but I still get the "frequency out of range" error after a reboot. I have swapped monitors to no avail (monitors that work on my other Debian 32-bit systems). I really don't think the problem can be the xorg.conf file, since I have tried the exact same file as on the other machines. (Also, those systems seem to be more than happy without custom HorizSync and VertRefresh options in their xorg.conf files.)
On this new computer, I am using the motherboard's integrated video output (theoretically a ATI Radeon HD5200).I don't know if special options are needed in xorg.conf for this???I am able to successfully boot to GUI with multiple differentCD Linux distros; however, no such luck with the Debian installation. I would prefer to stay with Debian if possible, but I cannot live by command line alone on this system.Please let me know if there is something else that I should try before punting and moving to another 64-bit distro.
Some time ago I've opened a thread about ACPI - as it turned out - killing my server. You may read it here if interested.My question is how can I enable Hyperthreading support in my kernel without enabling any part of ACPI?(Boot flag acpi=ht causes the same issue as described in above thread, so enabling any part of ACPI in any manner is not desirable)My kernel:
[root@sheridan ~]# uname -a Linux sheridan.******** 2.6.35.11-83.fc14.x86_64 #1 SMP Mon Feb 7 07:06:44 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
I'm running Ubuntu Server 9.10 on a dual socket X5550 platform with hyperthreading disabled. There should be 8 cores available for running processes: dual-socket, quad-core. When I start 8 single-threaded, cpu-intensive processes running, top shows six processes running at 100% and two at 50% (presumably sharing the seventh core). No other processes are reported as having >1% cpu, and yet the 1-minute load average is listed as over 11.0?!
1) Why is it not running each process on its own core? 2) Why is the load average so much greater than 8? 3) Is there anything I can change in the configuration to fix this?
