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 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.
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.
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?
I finally got everything installed and then slackware setup prompted me to reboot. then i did and it just took me back to windowsxpx64. so then i tried booting off my usb, and it worked, however when i login as root, i just get the bash commandline and not interface or programs or anything. i cannot login as any other user and the setup did not prompt me to make another user account. so how would i activate lilo or make it so i can boot with it to slackware? i rather use grub but for now i would just like to get slackware working right.
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 just installed debian Jessie (8) and find that the system cannot resolve URLs. Checking with the "hosts" command confirms this. I am connected to a comcast network in my house. I have looked over some of the documentation and it seems like there are several conflicting ways of setting up the resolver. It is not clear if the install process did this for me. I am assuming that DHCP was installed as the computer had no problem defining IPs for its wlan0 and eth0 ports and I can telnet in from and in-network PC. I have a few questions :
1) I see /sbin/dhclient/,,,,, running so i assume this is the DHCP deamon in use? 2) Before I dig too deep I wonder if an internal firewall is involved. Is there a command to shut it down temporarily? 3) what would I look for to determine if a resolver was installed and which one?
I see from my windows machine an apparent comcast DNS server but I don't believe I can code it into resolv.conf on debian as the OS now overwrites this(I already tried and failed!).
I'm running Fedora 12 and the last couple days I have noticed my screensaver will not start anymore. I did a yum update a few days ago don't know if there is a connection between the two. I've just started to Google the topic. Found different culprits ranging from dbus problems to buggy code.
I'm using a x86_64 PC running kernel 126.96.36.199-170.fc12.x86_64. My Gnome version is 2.28.2. The Gnome-screensaver version is 2.28.3-1.fc12.x86_64.
SSH is initially installed and activated. What are the steps in activating FTP and Telnet on Fedora 10. I know they are non-secure and probably shouldn't be used at all, but I need to know or at least pointed in the right direction.
