Debian Hardware :: Disabling Intel Turbo Boost On All 4 CPU
Jul 21, 2015
Due to some reason every-time I boot the laptop the power governors reset themselves to "ondemand". Which causes my laptop to overheat until it shut-downs. I tried adding this line to grub Code: Select allGRUB_CMDLINE_LINUX_DEFAULT="intel_pstate=disable" which kinda worked, but only on cpu 0.
Code: Select allcpufreq-info

I've got a dual Xeon 5570 (Nehalem) server. It clocks down properly, but never, under any circumstances that I've found, clocks up past its TSC. Even when running basically nothing but cat /dev/zero > /dev/null, nothing gets clocked higher than the TSC. Below is the turbostat output, which clearly knows what the hardware is actually capable of, but it never actually achieves it. I'm running Lenny, with backported kernel 2.6.30-bpo.2-amd64. I tried the 2.6.32 backport and there wasn't any difference. know where I should look next? BIOS settings? Do I need to change some kernel option and recompile?
# ./turbostat Nehalem multiplier 22, TSC frequency 2933 MHz Nehalem 4 cores active: 24 mult, max turbo frequency = 3200 MHz Nehalem 3 cores active: 24 mult, max turbo frequency = 3200 MHz Nehalem 2 cores active: 25 mult, max turbo frequency = 3333 MHz Nehalem 1 core active: 25 mult, max turbo frequency = 3333 MHz
I just installed a new HP DL360 with 32 GB of RAM and a Intel Xeon X5550 which supports speed stepping and turbo mode. I've enabled turbo in the BIOS, but cannot seem to get CentOS 5.4 to make use of either of these features. I've been googling for a solution for a while now, and tried various things, such as installing cpufreq. However, when I type cpufreq-info, I get this:

I'm trying to cross compile something and it requires a recent version of Boost. I'm using squeeze and gnome and my updates are all up to date. I could not get through the 'configure' stage with Boost dev packages from the debian repository, so I went to the Boost web site. I thought the package requires boost 1.44 or later, so I downloaded 1.45.0 from the site and proceeded to build and install it. I think I installed it right, using /usr/local/ as the prefix. Back at my main project, I try to configure my build and I get some of the following text and then the configure stops.
Code:
checking for Boost's header version... 1_45 checking for the toolset name used by Boost for arm-none-linux-gnueabi-g++... configure: WARNING: could not figure out which toolset name to use for arm-none-linux-gnueabi-g++ checking boost/date_time/posix_time/posix_time.hpp usability... yes
[code]....
I cannot get past the 'date_time' thing. Does anyone know what is meant by 'flags to link with Boost date_time' ?
I'm a Debian testing user (not an experienced one) on laptop Dell Latitude D531 and has encountered a problem: I've often got my laptop slowed down very much and the message appears in a console: Disabling IRQ #19 I've searched for the solution, but failed finding the answer.
dmesg showed:
Code: [ 21.064461] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready [ 21.067790] cfg80211: Calling CRDA for country: GB [ 21.160654] padlock: VIA PadLock not detected. [ 23.545837] fuse init (API version 7.13) [ 24.354533] tun: Universal TUN/TAP device driver, 1.6
Let me quickly state that I am returning to Debian after quite a long break. I am trying to relearn some things. I suppose I'm somewhat old school. As in I originally installed from rawright, back in the days when you had to do practically everything by hand. I was quite happy with config and make. I actually learned a ton back then, as I started out knowing nothing. I guess I can learn to catch up with the modern linux world.
Anyway here is my question? In the old days if I wanted something not to be mounted I would simply comment out the entry in /etc/fstab. I notice that my USB drive is mounted but does not appear in the fstab. It is in mtab, and lsusb does show it.
If I wanted to secure a system, but not totally remove usb support from the kernel, how would I prevent the automounting of USB drives? What are the configuration files that govern their operation?
Whenever I open a folder with the default browser (Nautilus), it does a quick scan of the contents. This is not a problem for normal folders, but it becomes one when a music folder contains several thousand files (I haven't yet tried with folders containing large amounts of non-music files). In such instances Nautilus sits there scanning and I can hear the hard drive seeking for a good while before it presents me with the contents of said folder. My music folder, for instance, contains some five thousand ogg files, and I have to wait *counts* a full minute before it displays its contents. I tried telling it to never count the number of files in the options, but it didn't help. So far, the only solution I've found is to use pcmanfm instead, which apparently does no scan and displays my music folder practically as soon as I click on it. Still, I like Nautilus more for everything else, so I'd much rather use that instead.
I have an ATI Radeon 5850 card with 2 17" monitors, plus a 46" TV via HDMI (disabled, except for BD plaback under windows) under Debian 6.0/Squeeze. When I first installed this system, it worked fine with all 3 screens (only 2 enabled at a time). Sometime in the past few weeks though, it's decided to revert to a single-display setup. I can't find any errors in the logfiles, and it works perfectly fine when I re-enabled the secondary display via the ATI Catalyst Control center.
The auto-generated xorg.conf isn't configured to use the second display (even after re-generating one using "aticonfig -initial=dual-head"), and it is not being modified when I change settings in the Catalyst Control Center.Updating display settings after every boot is just a bit annoying.
I have a Debian computer with 2 network interfaces. Ath0 for wifi and eth0 for cable. They're configured as dhcp and are getting their ip from different routers. When I shut down one of the router, it takes 5 minutes for the ip address to "Go away". I would like this to take a shorter time. I figured it must be a setting, but my attempts so far have been unsuccessfull. Is there a way to do this?
I'm trying to stop all boot time messages from appearing -- basically I'd like to have a simple blank screen from grub to xdm.
I tried everything -- used the "quiet" option in grub's config, added dmesg -n 1 to rc.local, changed console=ttySx, set kernel.printk in sysctl.conf to 4 1 1 7, and even eradicated rsyslogd altogether... to no avail. I still see all sorts of messages on my screen.
Dell Latitude C610 laptop with Debian Squeeze.I am using the computer as a print and file server, accessing it with ssh, so I don't need the display (which is busted anyway). I want to close the lid without having the computer suspend. Could not find a way to make it happen with gnome-power-preferences or the BIOS settings. There is a script, /etc/acpi/lid.sh, that runs when the laptop lid switch changes. Part of the script is shown here:
Code: Select allgrep -q closed /proc/acpi/button/lid/*/state # this is a file of 1 line like "state: open" or presumably "state: closed" if [ $? = 0 ] # The brackets evaluate to True when the lid is closed. then if [ x$LID_SLEEP = xtrue ]; then [ -x /etc/acpi/sleep.sh ] && /etc/acpi/sleep.sh # i.e., if this file exists, then run it. exit fi ... there's more ...
The stuff that gets executed after the if [ #$ = 0 ] is the stuff that suspends the computer. So I just replaced the brackets with something that is certain to be false, so it will never happen:
Code: Select allif [ 1 = 2 ] I admit this is FAR from an elegant solution, but it seems to work and it doesn't fubar the system.
i am running some programmes on gcc compiler and i have to check same programmes on turbo c compiler. But i do not have this c turbo compiler.i have done some searching and found that it is not possible to install turbo c directly ,for this i have to use dosbox.ok now the main question is that for this i must have c++ setup which i do not have.
I know that I can use the GUI (gnome-volume-properties) enable/disable the USB sticks/disks automount features, by checking/unchecking the pertinent options.My question is: how can I obtain the same results from the command line (that is, without using any GUI frontend)?
I have used TurboTax online for several years to do my return....this year they are refusing Firefox running on a Linux OS!Anyone know of an alternative that is Linux friendly?
I'm building a Debian Live system, [URL], and I've pared it down to a very light distro. It is using the IceWM, has the basic linux commands, and very very little else.
When I run "top" and "ps aux", I see that I have multiple terminals and logins waiting to be used. It's a small amount, but I'd like to make that RAM usable elsewhere. The indicated commands are: "/bin/login -f" and "-bash", and I have one of each associated with each tty[1-7]. I may want to keep tty1 and tty2, just in case, but I can't imagine wanting 3-7.
So, what I'm looking for is a way to stop tty[3-7] from even starting in the first place.
I saw on one forum the suggestion of modifying the /etc/init/tty[1-7].conf files, but these files aren't present, I presume because it's a "Live" system.
In Debian 8.1 with KDE, I don't find how to disable the automatic resizing of windows when the mouse drags a window to screen edges; seems that this function is called "aero snap".
I have a HP Pavilion Dv71245dx Laptop running Debian Wheezy, which has been alright so far except for the mouse wheel built into the right side of the touch mousepad. It's positioned in such a way that makes my thumb hit it all the time by accident while typing, and it's been a total nightmare. I would just like to disable the scroll wheel feature on this mousepad entirely, but I would like to do so in such a way that I can still use the scroll wheel on my USB mouse whenever I have that plugged in.
I have Phenom II X6 1055T. If Turbo Core kicks in, the speed should go up to 3.2GHz.
Problem is, it never kicks in. My kernel enabled Turbo Core already.
dmesg :
I am guessing, TurboCore depends with the P-State reading and cpu frequency thingy. As you can see, P0 are not 3200MHz (if my hypothesis are correct). Or perhaps i am wrong. I tested by not doing nothing and running folding program on one core with conky monitoring. Conky reads 5 cores at 800MHz, and one core at 2.8GHz.
TurboCore is enable on windows xp. I can see the core sometimes goes up to 3.2Ghz occasionally.
I have installed Ubuntu server 10.10 on my new computer which uses AMD Phenom II X6 1090T. But I have noticed that my CPU cores were not able to run at 3.6GHz at any time, even when I only have one CPU-intensive computing job. They are either at 3.2 GHz or 800 MHz, like this
Code:
$ cat /proc/cpuinfo | grep -i "cpu Mhz" cpu MHz: 800.000 cpu MHz: 3200.000 cpu MHz: 3200.000
[code]....
My maximum CPU frequency seems to be locked at 3.2 Ghz:
In our college all the systems (running on windows xp) have TURBO C/C++ installed on them which we use for C programming. I recently installed ubuntu 10.04 on me laptop (DELL Inspiron 14R (N4010) with some modifications) i read somewhere on the internet that Gedit can be used for writing a programme in ubuntu which can be compiled using gcc. Well if i use Gedit rather than Turbo c will i experience any differnce?, i mean is there any problem in doing so?? Or i should prefer running turbo c using DOS BOX?
I've clean installed over a friend's win98 with Mint 7 (disc from lab a year? or so ago).
My Optus modem prompted the wizard and now always works fine,ok speed, and I updated Mint with 300 new files etc.
But my friend's new Telstra Turbo modem,[Sierra brand] although it shows a blue light flashing, doesn't get the wizard connection process started, and there's just NO sign on Mint that it's plugged in.
If I can get it to work, it will increase the number of people I know who use linux to 1.
I have an acer 532h aspire one, running ubuntu 10.04.
Basically, I bought a Telstra Turbo USB broadband stick and I've been having a bit of hell getting it to work. First I couldn't get the computer to recognize it had been plugged in at all. I downloaded the modeswitch packages to no avail. I tried a few other terminal tweaks but they didn't change anything either. I left the card in and restarted the netbook and it finally recognized the wireless card. I was able to surf the internet for an hour or so a couple times. But after stowing the computer away for a couple hours and turning it on again, I found that this work around was no longer effective. So now I'm back to the blue light never blinking and I have to tether my phone and pay ridiculous data charges because I'm in the middle of nowhere.
I'm really new at troubleshooting things that don't work right out of the box.
It's a telstra turbo prepaid wireless broadband. The stick isn't even recognized as removable media.
I could't find the 64bit Debian Lenny OS for Intel architecture.Hence I have installed amd64 and it is working fine.Does both intel and amd have the same 64 bit OS amd64 ?
I'm trying to build boost on a 64-bit CentOS 5.4 install. I have Python 2.6.4 built and installed at /opt/Python_2.6.4/, and I've appended the user-config.jam file with:
The standard system Python is 2.4.1 but the tools I'm using require 2.6, so I've built this version and installed it independently of the system version 2.4.1 to avoid any conflicts.
As I'm sure you've already imagined, I get the error:
LONG_BIT definition appears wrong for platform (bad gcc/glibc config?)
I see that this is a long standing bug, but I have yet to find a fix. I've tried various CCFLAGS, CXXFLAGS, etc. to push for a 64-bit compile or a 32-bit compile (-m64 or -m32).
The offending file is pyport.h - is there a 64-bit friendly version that I don't know about?
