Ubuntu :: 1 Of 2 CPUs Always Stuck At 100% Acer Asprire 5738G Dual Core?
May 1, 2010
I have fresh install of Ubuntu 10.04 LTS Added Wine from Software Center but have no any Win apps loaded or running yet. I have also enabled visual Effects and the system installed and enabled NVidia's driver for the video-card after which the picture quality improved.
Here is the screen of my CPU monitor (sorry labels arre in Russian but the charts are quite intuitive) As you can see this 100% load "jumps" from one core to another periodically. On the Processes tab there is nothing fancy:
Less than 10% processes load. I have tried to play with CPU Clock Gnome widget, it doesn't really change the picture whether I use MAX CPU clock of 2Ghz or reduced power-saving 1,2 GHz. I have found couple similar cases on forum but see no solution so far.BTW, I have already launched the update manager and currently Ubuntu does not offer any new updates.

PS. In the attachement - Report of some built in System Diag Tool
I have a question that has been partially answered in other posts and forums but I am still unclear. Please can someone help me out? I was previously using an Intel Atom 1.6GHz, 1GB RAM and the onboard Intel graphics adaptor for use as a media center PC. This was running Lubuntu and I could use Flash at full screen without any issues.
I have since decided to upgrade to an Acer Revo R3610 (Dual core Intel Atom 1.6GHz, 4GB RAM, Corsair SSD and Nvidia ION grpahics). I thought that as this machine was more powerful than my previous one, I could get away with ditching Lununtu and go for Ubuntu 10.10 (x86).
I have updated the machine and installed the latest Nvidia drivers. When I browse to a Flash based site all runs fine until I go to full screen then I get about 10FPS (sound remains fine). The video is unwatchable. I rebuilt the machine using Windows 7 Ultimate (x86) and tested again. Under Windows the video plays perfectly.
I have also tried using the 10.2 beta version of Flash under Ubuntu and this gives the same terrible results. I am at a loss as to where the issue lies. Is it with Nvidia's driver, Adobe's Flash under Linux or is it my Ubuntu build?
I have just purchased an AMD Phenom II 1055T 6 Core CPU to replace my aging CPU. The problem is only 1 core is visible to Ubuntu, Does it actually support 6 cores?
I'm using Ubuntu 10.04 x64, and I have an AMD Phenom 2 x4 940 CPU. First I have to underline that four cores worked perfectly in previous versions of Ubuntu as well as Windows.
When looking at system monitor it tells me that I have two CPUs/Cores, it should be four.
This is the output of CPU info:
Code: processor: 0 vendor_id: AuthenticAMD cpu family: 16 model: 4
i am running gigabyte GA-M68M-S2P and AMD sempron 2.7. the problem is when i try to run dual core. it will boot and run for 2mins then it crashes. single core runs perfect.
I have now installed Wheezy on two different hard drives and in each case it seems only one CPU of my dual core CPU computer is recognized. System Monitor, Gkrellm and lscpu show just one when prior to the new install the old Wheezy showed both CPU's. I have put the hard drive into two other computers with dual core CPU's and all show just one CPU.
Interestingly System Profiler and Benchmark (hardinfo?) > Devices > Processors now show a large amount of processor infomation when with the old Wheezy I would only see both CPU's listed and nothing else.
I recently read in a forum that by default the Linux kernel only activates one of two cores in a dual core processor. Searching online gave one option to find out and that was the mpstat command. I therefore ran the command and got the following output.As the result says, it shows only 1 cpu. I was wondering what I could do to activate both cores in my machine, and whether doing so was going to cause me any problems.
Im running 64bit centos 5.6 and using virt-manager.On one of my guest OS's, Windows 7, The max Physical CPUs is 2, you can have unlimited CPU Cores however. (like my machine i use for work has 1, 4 core processor).The issue im having is xen only allows you to set the vcpu arguemnet in your xen config file. How can i set it so that 1 CPU has several Cores just as windows would recognize this machine if i were installing directly to the hardware vs via a VM.Ive searched for 2 days staright trying to address this issue, very little progress, Does anyone know where a XEN support forum is? all i get is the citrix xen support forums.
here is the best info i have found on this, but i dont know how to change this for my CPU to work, when i enter this in my xen config it essentially ignores it and just takes the value of vcpu= so windows shows 2 CPUs each with ONLY one core. Id like 1 or 2 CPUS showing Several cores.The physical Hardware is 2x Xeon 5300 Quad Core CPUs.

I have a dual-core computer that I just upgraded to lucid lynx. when looking at the system monitor, one of the cpu's is always running at 100% and its not always the same one. Is this normal or do I have an issue? I would really like some info.
Interested to find out if this is normal or not. I am running a Intel Core 2 Duo processor and the system monitor keeps showing one of the cores at 100%, and the other fluxuating normally. Is this normal or a bug with the system monitor. I am running Compiz, but that is pennies to the comp. It seems that about every 1.5 minutes the cores "swap" the 100% usage, but it always ends up with one core at 100% and the other core doing normal stuff.
my laptop fan was blazing like crazy for a while with only firefox and pidgin open. and even after closing firefox, it still continued. i took a look in htop, and appears that python is sucking 100% of 1 of the two cores all the time. it occasionally swaps core, but it always keeps 1 core completely occupied. i'm currently on lucid x64.
Now this is a fresh install of Ubuntu 10.04. I have done nothing but follow the steps on installing flash and ati driver from the main site. I have this problem on my desktop too which also has ATI graphics but with a AMD cpu. The desktop was upgraded from Ubuntu 9.10 and the driver installed from ATI site like my laptop. This is really troubling because while the video is in full screen its using over 90% of my cpu?? Then my laptop gets really hot so I just switch back to Windows 7(which only uses 15%). Last time I had this problem was with the FGLRX proprietary drivers on Ubuntu 9.10 with the desktop.

I have installed Ubuntu10.04.1LTS in my Desktop amd64 computer. I also downloaded the same version for i386 processors and tried to install the OS for my HCL Pentium Dual Core T4300 @2.1Ghz 4GB RAM laptop, details of which are given in the following two screenshots: dscf0105.jpg and dscf0106.jpg I already have Debian Lenny 5.0.4 installed on the laptop dscf0104.jpg and the laptop works fine when I run the Debian OS or Knoppix liveCD image stored in the HDD of the laptop. We all know that the Ubuntu LTS live CD leads to the following option: Screenshot.jpg However, in my laptop the operation freezes before we can reach the above option. The screenshot explains the situation: dscf0107.jpg I know I could always use one of the alternate downloads and install the OS from it. But my point of contention is: where is the matter going wrong? Can't we use the graphical installer CD to do a CUI installation?
I'm a Linux Mint user, but I'd like to cross over to Debian. I used the x86 architecture for the Mint install, but I couldn't find that anywhere on the Debian site. what the architecture for the Intel Pentium D dual core is?
I just installed Windows 7 Ultimate on my computer and I want to install Fedora Core 11 and dual boot my system. I have been on the net looking around, but I can't seem to find any suggestions on how I would do this. Can someone help me or give me a URL(s) that will give me a step-by-step guide on how to install Fedora Core 11 on a Windows 7 computer?
I have the latest everything (kernel, nvidia drivers and kde) and there seems to be a problem in that if I click on the K menu, or grouped windows in the taskbar, or anything in the notification area which causes the computer to freeze for 7 - 12 seconds. Anyone have any ideas what could be causing this?
It's an AMD 64 dual core with a GeForce 210 pci-x graphics card. The issue happens either with out without compositing.
I just got a new acer laptop that came loaded with Win 7, and I want to dual boot with Ubuntu. Naturally the laptop didn't come with a Win 7 disc, but instead has the stupid recovery partition. I've made the recovery DVDs from the eRecovery program but....
From what I read the acer recovery setup is extremely picky and will refuse to work after the partitions have been messed with. Apparently the ALT+F10 to start the recovery process on boot won't even work if acer's MBR is overwritten. What's worse, even the recovery DVDs won't work without the MBR! (At least from what I've been reading... I guess if you install a different HD you are SOL) So how does one get around this? I couldn't care less about acer's stupid recovery partition, but if I ever need to send the computer in for service I think they actually charge extra to restore their crap.
I have dual monitors that I have set up with two separate X screens with the nVidia control panel. For some reason at times when I move my mouse between the two screens, the cursor will start flickering rapidly between the adjacent edges of the screens and the system will become completely unresponsive, forcing me to do a hard reboot (the keyboard doesn't have a SysRq key).
I installed Fedora 15 on my relatively new Laptop machine and stumbled upon an odd thing:Even though my CPU is an Intel i7-640M dual core (2x 2.8 Ghz) it somehow seems to be recognized as a quad. System monitor shows 4 CPUs (all of the used to some extend) and even "cat /proc/cpuinfo" gives me 4 processors:
Code:
processor: 0 vendor_id: GenuineIntel cpu family: 6
[code]...
At the same time the system (while relatively stable) is incredibly slow when it comes to complicated calculations (I do neuron simulations on a custom C++ framework).
I have an Acer 1200X with an Nvidia 8200 graphics GPU integrated on the motherboard. I have an HDMI and VGA output. I have downloaded the Nvidia graphics driver using envyNG and the old fashioned way. I have tried configuring the monitors 15 ways from Sunday in the configuration and I cannot for the life of me get dual monitors to work.
When I go into configuration with the Nvidia wizzard it blanks like its going to work then just stays black with the mouse cursor. I also cannot save as I get a "parsing" error. I am using Ubuntu 9.10 and have even tried using envyNG to get the monitors to work on twinview... NOTHING Hope someone can help!
My dad who is a Linux nut came over to help and he left 3 hours later because were tempted to chuck the computer out the window...I need to figure this out as this is going to be my work computer and I need dual screens.
I'm thinking of buying an Acer Aspire D250 loaded with Win7 and then adding a version of Ubuntu.
The netbook will come with the Acer recovery facility to reinstall Win7 from a recovery partition in the event of OS failure. This means that the MBR and subsequent loaders need to be preserved for this function to remain (I don't have a Win7 disc and don't want to have to buy one).
I'm happy with a basic Win/Linux dual boot setup but I'd value any comments/suggestions as to how to preserve the recovery function when I add Ubuntu.
Compiling a kernel on this machine first time and get upset with which processor family/type/options to select for my Intel Pentim Dual Core T2390.Does sombody know how to configure kernel better for this processor?
I have a command line OCR program called OCR Shop XTR (Vividata corp) that I am using on a system with a 6-core AMD chip. I changed the bios so that the 6-cores were activated, but htop shows me that while the program is running, I am only getting activity on one core (the program maxes out the one core with consistent usage between 97% and 100%).
I have read that many programs are not written to take advantage of multiple core cpu's. However, I am just hoping that there is some way to get this program to take advantage of the extra cores. Does anyone know of a way to invoke programs from the command line which would spread the workload out among additional cores?
