Ubuntu :: 10.04 - BIOS Does Not Support CPU Scaling
Jun 26, 2010
I've been trying to get lucid to work on my gateway netbook. The major problem I've seen is that it would overheat (to about 63 C or a little higher, and then the display would go crazy and crash. My BIOS doesn't support cpu scaling. Somewhere in a google search, someone mentioned the 2.6.34 kernel. I had no ideal what I was doing, and I installed this kernel. (could not install headers -- a dependency issue I didn't understand). Tried it, and it booted.
Saw some errors, like timer or something not found and something about a soft reset. However, it boots, and it works, and the temperature is much better (at least for the last 42 minutes: I've not been able to run it that long before). Are those errors likely to cause problems? Are there any issues I should be aware of using a non-standard kernel like this? I am dual booting with 9.10, which works well, and all my serious work is on the 9.10 partitions.

As I write, temp is still at 56, but I am getting some intermittent display problems. Should I give up on lucid?
Is there a way to install Linux over the network without support in the BIOS (PXE if I'm not mistaking)? Something like the USB thing (boot from CD for drivers and after that the USB). 10x!
I'm trying to install ubuntu Linux on a Pentium 3 computer which does not support booting to the CD-ROM drives. What are my options on other ways to install? Could I either use a 3.5inch floppy disk to get it started or install on another computer and just switch the disk back over right before configuring all the hardware?
Well, after installing the 64-bit RTM release of Windows 7, I finally became too fed up to stand it anymore. My BIOS does not recognize more than 3 GBs of RAM and therefore even my 64-bit Operating Systems (Windows 7 and Fedora 11) can't see or use the extra gig. Is there any way to get another BIOS or to add the support to my existing BIOS?
Oh, before I forget, I am using an Acer Aspire 5630 incase the model is required.
i just downloaded Ubuntu10.10,i used to burn the .iso file to a cd and then boot using the CD. recently my cd/dvd writer crashed and i was wondering could i boot from my pen drive in such cases,i also prepared a bootable pen drive but in my BIOS settings there is no option visble for such booting.
i just downloaded openSUSE 11.4,i used to burn the .iso file to a cd and then boot using the CD. recently my cd/dvd writer crashed and i was wondering could i boot from my pen drive in such cases,i also prepared a bootable pen drive but in my BIOS settings there is no option visble for such booting.
I recently started to build a new box based on this board: [URL] All is going well enough except for very poor sound, and before I go any further trying to sort it out,it seems smart to update the bios as I am 5 or so releases back. The readme with the bios flash utility/file says to use a win98 boot disk + bios/utility floppy but the bios file itself is much too big to fit on a floppy anyway so I haven't been able to create a floppy-emulating cd as most discussions seem to suggest doing. I'm sure I'm missing something, but there has to be a way to take a win98 boot disk image, plus 2 files and get that to either boot from cd or better yet usb drive.
I'm about to install the Smart Boot Manager rpm so that I will be able to boot from my usb. My bios doesn't support booting up from the usb port. Will this cause conflict with grub?I currently have Fedora 14 installed and about to install CentOS 5.5.
i'm currently using windows vista and want to boot opensuse11.4 from my usb drive but my BIOS doesn't support it. please explain steps to install it on vista hard-disk,i'm getting confused following steps posted on theris website
I'm trying to boot an SD card on a notebook that does not have BIOS support for booting from the SD slot. Using various how-to's I've figured out how to add additional SD card modules to the initrd.img file on a bootable USB drive such that I can boot Linux installed on the SD card.
However, best I can tell, it loads the kernel and initrd.img from the USB and everything else from the SD card. What I really want is to load the necessary SD modules from the USB and then chainload the SD card such that whatever kernel is on the SD card is loaded instead. Is it possible to chainload to another bootable device after the kernel (with the SD module additions) has already been loaded?
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 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'm running ubuntu 10.10 64 bit. CPU speed scaling says my CPU (AMD PhenomII 1090T) is not supported, and shows full speed on all cores, regardless of load. I've read that those issues were solved in kernel 2.6.34...
How can I make it work? or do I have to wait for an update?

i face problem with Firefox 3.6.11: smooth image scaling doesn't work. When i zoom in websites (ctrl +), images are not anti aliased, but appear pixelated, which is very ugly.
What I found out about so far, this seems not to be a FF problem (FF3 should support smooth image scaling), but a problem with the video driver, who tells X it could do smooth image scaling automatically but it cant. There is also a "bug" fix for the FF:
launchpad.net/~firefox-smooth-scaling/+archive/ppa I putted this to my package sources and made a system update. But smooth image scaling still doesn't work
I am trying to set up my cpu freq. scaling to ignore BOINC. From what google has shown me this is done by setting a value of 1 for ignore_nice_load. However the location of said value does not seem to be the same in 10.04 as in the results from google. How do i set this or is there a better way to keep idle processes like BOINC from increasing the my cpu frequency?
Basic Info: Ubuntu 10.10, AMD RM-70 2GHZ Processor, HP G60-120US, Bios F54. I'm unable to scale my processor (either core) using the applet in the menu bar. Every time I try, I select 2GHZ, and re-open; then it's displayed that 500MHZ was selected. I'm unable to pick any speed, the computer has a mind of it's own in that sense. It's essentially stuck at 500MHZ for 98% of the uptime, which makes it impossible to do anything more than web browsing. Ex: I tried watching an HD video, I watched 5 min, and 1,400 out of the 10,000 or so were dropped!
Since the new Unity in Ubuntu 11.04 doesn't work with applets, like GNOME, I've lost an useful applet to choose the operating clock of my CPU as well as power profiles (Performance, Conservative, On Demand etc.).
I've looked into Ubuntu Software Center but couldn't find anything similar.
I managed to half fix my earlier problem of being unable to clone my desktop monitor to my TV. I set the configuration to TwinView, and the resolution to the same as my desktop (Doh) and that seemed to at least get my desktop the way it used to be.
The problem now is the TV. It's cutting off a lot of pixels, and I can get it almost to fit if I enable flat panel scaling and set GPU Scaling Method to "Centered". However, when I restart the X server, it always returns to "Stretched". I've tried saving it from nvidia-settings (nothing seems to happen to the xorg.conf file,) and ala [URL] s have tried to put some version of
I have a Core 2 Duo T9600. I noticed video playing performance has been really bad lately, and videos that used to work fine now stuttered. I would say it started happening 2-3 weeks ago. I discovered the culprit is that the CPU is scaling down to 800Mhz and sticking there. Running cpufreq-info yields:
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 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:
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 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:
In order to save power and to cool down my Debian system a little bit, I installed cpufregs the other day and changed it the cpu gonever to on_demand.
Well I came back to the box today and powertop tells me that the cpu has been running at 2.66ghz (max freq) for 99/99% of the time.
Running cpufreq says this: Code: analyzing CPU 0: driver: p4-clockmod CPUs which need to switch frequency at the same time: 1 hardware limits: 333 MHz - 2.67 GHz
In Lucid I cannot get CPU scaling to work anymore, in previous Ubuntu releases this was not a problem with the same hardware (AMD Phenom 9500 Quad). I used to load module 'powernow-k8' and 'powernowd' to make it work, but it seems 'powernow-k8' is not available in Lucid. Anyone who has cpu scaling working in Lucid?
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.
